How to make a Priming Manifold on top of my pool pump lid


Making a connection between dissimilar materials (hard/brass and soft/plastic) is difficult. For the best result, it is helpful to transition with one or more materials with in-between stiffness, and/or attach the valve to a wide plate and use a rubber gasket to prevent leaks/failure.

I believe that a good place to start would be to look for water heater pressure relief valve parts. Maybe it would be cheaper to get an old one from a scrap yard that you can cut apart. Or, try looking for some rain barrel parts or study the rainbarrel construction methods. As for the glue, once again, in-between stiffness is the best. Epoxy, silicone, calk, and silicone-caulk blends might all be...

When a system is fully primed, the system components, pipes, pump, filter etc., are filled with water and the pool pump is able to suck water from the pool and push it back into the pool through pool returns. Priming a pool pump involves purging air from the pumping system and filling the water lines and pump with water. The number of steps required to prime your pool pump depends on the amount on water in the suction side of the lines - water coming from the pool to the pump. If you are installing a new pool system, there is no water in the lines, and you may have to repeat these steps several times. If you are adding or replacing components into the pumping system (like a heater), there will still be some water in the lines and priming will be simpler. The following procedure assumes that you have no or little water in the system. Visible indications of low water are no or little water in the pump strainer box, and a low pressure reading on the pool filter pressure...

Many pool pumps nowadays are self-priming, meaning that they can automatically generate water flow after turning on, even if there are significant amounts of air in the system. Some pumps require you to manually prime your pump before turning it on. The follow steps will allow you to do so.

1) Turn off the system. When working on any pool equipment, your system should always be turned off.

2) Find your diverter valve that determines if your water comes from your main drain or skimmer. Take note of the position, and then move it so water will only come from one of the locations.

3) Open up your air relief valve on top of your filter to help remove any excess air pressure in the system once it is turned on.

4) Open up the lid covering your pump basket and remove any debris in the basket that may hinder water flow.

5) Check your pump basket lid for any cracks, and make sure the corresponding O-ring is still in good condition and...

Priming a pool pump can sometimes be a difficult process. If there are any deficiencies in the pump, the installation, or the plumbing lines themselves then this will make it much more difficult to prime your pump - maybe even impossible.

Pool pumps are centrifugal pumps and are referred to as "self priming" which is a misnomer. The pumps require manual priming to make sure the pump has water running through it. Running a pool pump without water will cause it to overheat and likely fail. Self priming refers to a pump that is able to evacuate air from the system. A swimming pool pump is able to draw air, however they are much more effective at moving water than air.

Fill The Pump Resevoir With Water
The process of priming a pool pump begins with adding a full strainer basket of water to the pump. You then tighten the lid on to the pump, ensure all the valves installed on the system or in the open position, and turn the pump...

The pool pump is the heart of the swimming pool. Sometimes the pool pump will be on but it is not moving any water. Pool pumps are designed to pump water and can handle a small amount of air in the system. If too much air enters the system, the pump may fail to move water or "Looses the Prime". Air can enter the system in many ways. It is important to determine why the pump lost its prime before you try to get it circulating again or you may not succeed. There are two kinds of pumps - "Self-Priming" and "Flooded Suction". The majority of swimming pool pumps are Self-Priming however; most pool cleaner pumps are Flooded Suction type. Basically, if your pump has a strainer basket on it then it is a self priming pump.

Be sure to keep the O-Ring on the pump lid lubricated with petroleum jelly to help the lid seal correctly and to allow easier removal of the lid. When the pump is operating correctly the pump lid is under suction and the pump will naturally squeeze the lid tight....

Your swimming pool pump must be "primed" in order to operate properly. When your pool pump is on but the pool water is not moving, the pump has "lost its prime". This means that air has entered the pump. Be sure to determine why the pool pump has air in it, instead of water, before you prime the pump again. Follow these steps carefully, to ensure you have covered every contingency. The safety of swimmers using your pool depends on the pump working in optimum condition.

Step 1- Figure Out How the Air Got In

Air is often present in the pump the first time you start it up in early summer, especially if you "winterized" your pool by disassembling the pump. Be sure you have reinserted and resealed all the parts you took out of the pool pump. Check that the water level in the pool is as high as possible and that it is flowing into the skimmer inlets. Inspect and clear any clogs and debris in the skimmer and the primary drain. Remove decaying leaves and hair from the pump...

Turn the pool pump off. If you can, shut off the the power to the pump.

Relieve air pressure. Turn the air relief valve on the top of the pool filter counterclockwise (anticlockwise). The gauge should read 0 psi. Leave this valve open.

Close all the suction valves. There should be one for the main drain and one or more for the skimmer lines.

Open the lid of the pool pump strainer box. Depending on your box, you may need to turn a knob counterclockwise (anticlockwise) and possibly do some unscrewing.

Check the basket in the strainer box for any debris or objects. If you see anything, take the basket out of the strainer box, clean and replace.

Fill the strainer box with water completely.

Replace the strainer box lid carefully and ensure a good seal.Check the lid of the strainer box and its seal. Note if there are any cracks or any other signs of damage. Apply petroleum jelly or a similar lubricant to the O-ring. Tighten...

The pump is an integral part of the swimming pool filtration system. Most residential swimming pools are expected to have enough pumping capacity so as to turn over the total volume of the pool in every six hours. In an average swimming pool, this means a circulation of 36 gallons per minute. This is quite a heavy load on the pool pump and other components in the system.

When your pool system is completely primed, the system components, pump, filter and pipes are filled with water and the pool pump is able suction water from the pool and gets it back into the pool via the return. Priming a pool pump involves pushing air from the pumping system and then filling the pump and water lines with water. Depending on the level of water in the suction side of the lines, you will have to follow a number of steps. If you are putting up a new pool system, it means there is no water in the lines and you may be required to repeat the steps several times. However, if you are replacing or...

The pump is the heart of a swimming pool filtration system. The Association of Pool and Spa Professionals publishes standards for swimming pool circulation. Residential pool pumps are required to have sufficient pumping capacity to turn over the entire volume of the pool every six hours. In the average residential pool, this requires a circulation rate of 36 gallons per minute; that’s a heavy load on the pump and other system components. It’s no wonder malfunctions and system shortfalls occur.

Pool Pump Theory

Pool pumps are installed below the upper water level of the pool in pump pits or underground compartments. Water is gravity fed to the pump inlet when the pump is off. Once the pump is energized, the inlet line is under suction and the pump outlet, including the filter and return line to the pool, is under pressure. Anything that disrupts that harmony may result in loss of circulation, even though the pump is physically operating.

Usually at the beginning of the pool season, when you open your pool, your pump might need a bit of priming. Priming is the act of giving your pump enough water so it will start pulling from the pool. Basically, it’s like giving your pump a motivational pep talk to get it in gear.

And now, let’s get started on how to prime a pool pump with these 3 easy steps!

1. Turn Your Multiport Valve to Recirculate

This will bypass the filter system, so that the water comes into the pump, through ONLY your multiport valve, and right back into the pool — never touching the inside of your filter.

NOTE: Remove any plugs you have in your skimmer(s) or return jet(s) so that water can flow into your pump.

2. Fill The Pump With Water

Open up your pump by removing the lid (make sure all the drain plugs are in place so that your pump doesn’t leak water).

Take your garden hose and fill...

Most types of groundwater pump have a piston that moves back and forth inside a two-valve cylinder (a valve allows water to pass in only one direction - in this case, upwards):

Suction pumps have the cylinder situated above ground or near the surface. This means that they can only be used for shallow wells. It is called a suction pump because pulling up on the piston creates a low pressure ("suction") in the cylinder, causing the atmospheric pressure outside to push the water up to the surface. Because atmospheric pressure is fairly low, the pressure difference between inside and outside the cylinder is only large enough to raise water from a maximum depth of about 7 metres.

Figure 1: How most types of pump cylinders work

It should also be noted that if a shallow-well is used too much, the water-table may fall as the underground reservoir of water is reduced. If this level falls below 7 metres, the pump will not...

There are times when you will need to drain your pool – to prepare it for the winter season, maintenance or simply to change the water after several years of use. Every pool owner at a certain point in time faces the question of how to drain a pool. Over the course of time, the TDS* level will reach a point, when you will notice mineral stains on the walls and floor of your pool. If left untouched, this high TDS level will cause surface deterioration. It is very unlikely that the level will reduce if you don’t drain the water from your pool. In many regions, pool owners also have to drain water from their pools to keep them as clean as possible for the next season and due to cold winter temperatures, which cause water to freeze and damage the pool surface and pipes. This article will show you a way of draining your pool with a pool pump and garden hose.

How to drain a pool

Here is a brief guide to how to drain a pool:

On older pumps removing your pump is pretty simple, there is a clamp with a way to tighten it. You simply loosen the clamp and it pops off. But on new pool equipment the lids usually slide onto notches that hold it in place. Even when tightened to a reasonable degree they can be very difficult to remove. So here is an easy way to pop it off.

Leave the pool equipment ON Smack both sides of the lid in a counter clockwise direction, it should budge and come loose. Turn OFF the equipment, now the lid will pop up and off the pump and water will overflow from the pump for a few seconds. Do whatever you need to do with pump and basket, replace lid and turn the equipment back ON. If you are having trouble getting the pump to prime, open the lid and check the gasket and make sure the lid is on tight enough.

This is a simple tip that can save you a lot of time if you have a difficult piece of equipment. If you are still having trouble with your pump, or any other part of the pool,...

There are lots of reasons, and some of them depend on the type of pump. If all the right valves are open, and the pump and piping are in good condition, then the most likely cause is that the pump is not primed. Most centrifugal pumps require priming. This is simply filling the case with water. Depending on the pump and the setup, you may be able to prime by causing water to flow backward through the discharge pipe. Alternatively, many pumps have a priming plug on top of the pump case. Remove the plug, fill the case with water, and replace the plug. If none of that works, then the next most likely cause is an air leak in the suction piping. Given a choice, your pump would much rather suck air than water (it's a lot easier). So, if the suction line from the pool to the pump has an air leak anywhere in it (cracks, loose fittings...) then it won't suck water. After those two things, would need more detail to diagnose.

James McGuire: Trying to find out what to do. I have a 3 way Jandy valve on my pool supply side, one for each skimmer and the bottom. The valve has gotten very hard to turn. Is this something i can "fix"? Also is it ok to change positions while the pump is going? I have no problem with the prime, just moving the lever.

Mike Murray: Thanks man....$20 for rings and lube, fixed my problem.

Tony Bunch: My brand new pool pump is on a timer and it turns off at the time set for and it comes on in the morning that the timer is set for but it will not prime. I go outside and set it for spa and it will prime and work on spa mode and then when I put back in pool mode it will prime and work with no problems, any ideals? Please help!

Bludika: For some reason my pump prime goes down when my vacuum is connected to the skimmer and I do 100% pool suction, but it goes back to normal when I make it 80% pool/20% spa suction, any ideas?

Every swimming pool pump will break down at some point, and when it does it can have a huge impact on your pool that you may not be realizing. The good news is that most of these swimming pool pump problems can be troubleshooted within a few minutes to prevent further damage that can cause even more repair work on the pump.

This troubleshooting guide will help you repair & troubleshoot many brands and models of pool pumps including such brands as Hayward, Pentair, Sta-rite pool pumps, and many others. The only difference is that some pumps will have different horsepower, name brand, but no matter what brand of pool pump you have they all will have an impeller and so on so this guide should work for you.

There are a few common reason that you pool pump will break down. Things like running the pump with a pool prime can burn out the seal and even over heat the pump fittings to a point where the pump won’t pull a prime at all. Other things include things like leaking...

We carry the other brands, but Hayward pumps and filters have always been our flagship line.

Reliable & durable, Hayward pumps will still likely need some type of troubleshooting at some point during your relationship.

Often what appears to be a pool pump problem is actually a filter problem or a valve problem, so the first step is to rule out any mis-aligned valves or obstructions in the filter or pipes.

Barring problems with other pool equipment, a pool pump problem will either be an electrical issue or a plumbing issue. On the electrical side, problems can occur with the electric motor, timeclock, breaker or wires. On the plumbing side, you can have problems with air leaks, water leaks or just getting the water to flow properly.
