Would it hurt my water pump if installed a second water pump on the output of the first?


Installing another pump after the primary pump may damage the primary pump, but even if it doesn't it won't solve your problem. The bigger issue is that if the line between the two pumps has any leaks, even microscopic, then you'll be creating a very low pressure in that pipe, which may lead to contamination. You would have to make sure the secondary pump is lower pressure, and this would defeat any possible benefit anyway.

Consider installing a low flow shower head. These are designed for a lower volume of water, and if you can reduce the volume requirements, the apparent pressure will go up. It will provide for a more powerful shower, without having to increase the actual volume or pressure of the existing system.

Beyond that, the only way to get more volume through an existing pipe is to increase the pressure. I don't suggest that you pursue this, though, as you may create or enlarge leaks in the piping you don't want to replace.

As others have indicated,...

Let your car sit overnight, parked in a garage with a clean concrete floor. If it's not possible to park it inside on a clean concrete surface, place a piece of light-colored cardboard underneath your car directly under the motor. Be mindful that water pumps are more likely to leak while the vehicle engine is running, so this is a poor reference for finding a leak.


Examine the cardboard the next morning. If it appears to be wet from coolant, you have a leak somewhere, possibly in your water pump, but other sources of leaking coolant could be radiator hoses, heater hoses, freeze plugs, gaskets, or the radiator itself. To narrow the search down, try to place the cardboard directly underneath the water pump itself. If you notice green liquid on the cardboard, it's antifreeze. This means you have a coolant leak somewhere.


Check the water pump pulley. Find the round part at the front of your water pump that the belt is around. Attempt to...

they're 2 distinctive areas, -- ninety 9% of the time you purely repalce the waterpump! The "housing is kind of the "decrease back of the pump assembly"! analyze this to having a flat tire- you could might desire to throw the tire away,-- yet you utilize the wheel lower back! As for the leak, it relies upon in basic terms what's inflicting it, - this is repairable, - or it could no longer, -- possibly there's a discrepiency interior the instullation additionally. this might purely be desperate by using an experienced mechanic that takes the time to look and see what's inflicting the leak! working example a chip or intense scratch in "mating surfaces might enable leak! -- often no sealer is needed while installation a waterpump, - the gasket usually compenstates for any "minor' discrepiences of this style (so sealer might desire to no tbe mandatory)! yet this same concern must be relatively solved with a sprint silicone "RTV" sealer, - it could fill the scratch or chip and...

Installing a water pressure booster pump is important if you want to increase water pressure and the volume available to your system, or increase the pressure but at a lower flow.

Testing Water Pressure

To find out how much water pressure is in the home, you should test your water pressure first. Attach a pressure gauge to an outside spigot. If the pressure reads below 30 psi, the water pressure is low. For most domestic situations, increasing volume is not an option and pressure boosting pumps are used.


A pressure booster system attaches to the main water line. A pressure switch turns on the pump, which pushes the water through a tube into the tank. One side of the tank has pressurized air, which pushes the water up and out of the tank into the plumbing system.

The installation of a booster pump on a city water system, or even a rural water system, that uses gravity-fed water, is quite easy. All you need to do is take the main...

Solar Water Pumping Guide


This guide is primarily about DC powered pumps, as used in typical solar electric systems. Information is also provided on using AC powered pumps on systems that have an inverter available. DC powered pumps are used for deep and shallow well pumping, stock tanks, irrigation, water pressure systems, and many other areas. This guide is recommended reading for installers, users, and well drillers - especially those that are new to solar electric pumping systems. DC pumps are different in many ways from the AC pumps that many people are used to.

Capabilities & Limitations

DC pumps come in a variety of types. One of the most common is the small pressure booster pumps (Shurflo) commonly used in RV’s to supply water from the onboard water tank. Others include diaphragm and piston positive displacement pumps for wells, booster (pressurizing) pumps, circulating pumps, groundwater sampling pumps etc.

Hello All,

I am putting this out there for anyone who may have a definitive answer for my problem. I am currently trying to install a U.S. standard 3 Phase water pump for my living facilities, But our site is powered by a European standard (220v / 50Hz) generator. The generator has a Bus bar setup with an output of 220v. The pump is a (208-230v / 440-480v / 60Hz) Pump.

When I wired the pump for Low "Y" Voltage Transmission the pump started to smoke immediately but the pump was moving for a short period of time. I am curious to find out if there are any alternatives or suggestions that might help me understand why 220v will not work on this pump??

the wiring diagram for "Y" or low voltage transmission is below:

Phase1 to 1 and 7
Phase2 to 2 and 8
Phase3 to 3 and 9
leaving 4,5, and 6 tied off...

Hi mates,

Im planing my first 110v project and im very worried about my safety.

I got this relay module from Itead:

At relay piece (HK3FF-DC5V-SHG) says clearly 10A - 250v.
I see a zenner diode and a transistor to activate the coil (check the photos at site).

I want to drive a water pump motor (110v-7A).
Turning it on 2 times per hour - 5 minutes on

Can I trust in this module for this task? Im worried
about pcb tracks thickness and spaces. The motor
will melt the tracks, pcb, connectors? Some eletric leakage
can happens?

The bottom is the same of this module from DX.

Another question. The splited wire going into relay module
is the positive? Is better the positive or negative?

This zenner diode will protect...

One of the biggest and most potent weathering forces at work in the world is water. It seeps into foundations, floods basements and works as a silent destructive force. A basement flooded with water is a breeding ground for mold, creating unhygienic conditions. Seeping water also weakens the house foundation, which makes it all the more important that this water problem be dealt with as soon as possible. If your house is built near a water source like a river or a lake in a geographical depression, you are bound to face the problem of water flooding in. The most effective way of dealing with it, besides sealing your basement is to install a sump pump, which can carry all the water away and drain it elsewhere.

Sump Pump Working

For those of you who are installing one for the first time, it would be instructive to know how sump pumps work. It will make it easier for you to choose the right pump for your house. All pumps are installed in or near sump pits which are dug...

Solar Energy is a giant leap in the field of science which has enabled humans to produce clean energy. In this step I am going to give you a brief introduction into real economics, viability and applications of this Instructable.


Agriculture in developing nations isn't as efficient as it really should be. One of the main problems of agriculture is water management. Even developing nations which receive a good amount of water through rainfall fail to be efficient in the field of agriculture.

The initial investment of solar energy is high. Buts lets put it in a developing nation's agriculturists/farmers perspective. I have chosen my country India as the perfect example of the best beneficiary from the use of solar energy. EXAMPLE based on past experience:

The common farmer over here has to pay approximately Rs 50,000 to setup an electrical connection to his/her farm depending on how far the nearest village transformer/power distributor is from...

The pump is literally the heart of your pool’s circulation system. But just like our own hearts, we have a tendency to neglect the health and well-being of the pool pump and then freak out when it’s not working properly. There are probably dozens of pool pump mistakes out there. . . here are our top 5.

Not Cleaning Pump Basket

Let’s start with the very basics. The pump strainer basket exists to catch debris but it can’t clean itself. You need to reach in there and get the gunk out. If you don’t, the pool will have decreased water flow which means reduced filtration and ultimately, the dreaded algae bloom. The pump basket should be cleared out weekly and even more frequently during the fall and spring when there is more debris in the pool. Learn more here about how to clean your pump strainer basket.

Running Pump Too Little or Too Much

If you've just installed a new water heater and find that the water pressure is lower than you expect, a series of tests can help you isolate the problem, which may not be the result of replacing the heater. A heater input or output pipe could be blocked, or the main pressure to the house could be low. If the problem happens only at a particular fixture, that fixture may be blocked or defective.

Water Tank Hum

New water heaters often are equipped with heat traps to improve energy efficiency, and you may hear a humming or whistling sound from one of the traps in a newly installed heater. The sound is produced by water flow being restricted, and that restriction also can cause low water pressure. The solution is to turn off the tank, close the water valves, unscrew the heat traps from the pipes and replace them with dielectric nipples that don't restrict water flow. Dielectric nipples have an internal plastic coating to prevent metal-to-metal contact between copper and...

If you have a basement in Indiana, then you know all about sump pumps. The problem is that these things fail all the time. While it’s not to say that we have a fool-proof method for preventing 100% of failures, there are certainly some tips you can follow to better your chances of a properly working sump pump.

For years, sump pumps have been a pretty common fixture in homes, especially in lower-level areas of the country or in places where the rapid melting of heavy snow can cause flooded basements. The popularity of sump pumps have grown exponentially in the past couple decades, largely in part to a legal amendment to the US Federal Clean Water Act in 1987 that requires certain homes to have a sump pump, even if they are not necessarily high-risk for floods.

The American Society of Home Inspectors actually did a study that showed more than 60% of American homes suffer from underground wetness or water damage. And there’s a liklihood that an ever large percentage will...
