How do I get the water pressure back?


I have what seems to be a strange, but hopefully easily solved problem. I have a Rheem Warrior series electric hot water heater in my mobile home. My husband is installing a new shower and we could not find the shut off on the heater, so we had to shut the main valve off under our home. Days later, we have plenty of hot water, but the cold is, lets say at half pressure. We have shut the main off and on a couple times, hoping that would do the trick, but no luck! I'm going to try cutting the power to the heater next to see what that does. I feel like this should have an easy solution and really don't want to call a plumber for something so silly! Any ideas would be...

Inspect the Pressure Reducing Valve.

Homes on low ground often have a PRV installed where the line enters the building. This valve, usually shaped like a bell, reduces the supply of water to a safe pressure for your building. On a typical model, you can turn the screw or knob at the top of the PRV clockwise to increase water pressure.


It's best to turn this only a couple times, keeping track of the number of turns. Going too far can damage your plumbing.

[5]If adjusting the PRV doesn't make any difference, shut off the water supply and disassemble the valve. You may need to replace a part or the entire valve, or just clean the parts. Finding manufacturer instructions is recommended. Not all homes have a PRV, especially if the city water supply is low pressure or the building is on high...

Ear pressure may feel like one or both ears are muffled, as though hearing is slightly impaired. It may easily resolve on its own in some cases, or it could require treatment, depending on cause. When ear pressure is caused by air pressure changes, it can usually be resolved chewing gum, swallowing, or yawning; if you have a cold or allergies, taking decongestants or antihistamines may help. For other conditions, like ear infections, a trip to the doctor may be needed. There are a number of things that may cause ear pressure, so before you attempt to solve it on your own, you may want to have a medical professional examine your ears to see if there is an obvious solution.

One very common cause of ear pressure is changes in barometric pressure. When people change altitude quickly, problems can occur in the Eustachian tubes and the ear can feel blocked. Many people have this sensation when they're on airplanes, and some will even feel it if they quickly climb a mountain in a...

I have the same problem, but there's really no answer for mine since I'm in a rental home (military housing), but I just thought I'd chime in all the same.

When I confronted a housing maintenance guy about the low water pressure problem when watering the lawn with my impulse sprinklers, which is even worse when water's running elsewhere, he told me it was normal & to look for low-pressure sprinklers.

After posting here about such I had my suspicions confirmed that the guy was feeding me a load of BS. I decided to ask around some more anyhow & checked out Home Depot, Lowe's, Target, Shopko & the Base Exchange & I think the average was 60 PSI to get impulse & oscillating types to run at maximum output, if it was even listed!

The problem lies therein, you see, with no water running elsewhere the approximate PSI/burst on the back of the house is 39/200-plus & the approximate PSI/burst on the side of the house is 36/168. Of course this goes down when water runs...

Low water pressure is a common problem for homeowners with a well, but it’s not a problem they have to put up with. There are many reasons for low water pressure; some can be resolved with a simple, low-cost fix, while others require significant work and money. The professionals at Skillings & Sons are experts at troubleshooting the causes of low water pressure. If you know for sure that low pressure is the problem, there are some easy fixes you can do to get the water flowing better.

Homeowners should understand, however, that increasing the water pressure when low water pressure is not the cause can damage a home water system and enhance the likelihood of a catastrophic water system failure. That is why we advise our customers with water pressure concerns to get a consultation from a professional first before taking any action.

If you’re like me, you enjoy having good water pressure. You might take it for granted, but having lived in a place where the water pressure was really low, I have come to appreciate the value of good water pressure.

There are really only two practical ways to pressurize water at your cabin. You can either pump the water up to pressure, or you can elevate the water source and let gravity provide the pressure. In fact, these two methods are the ones used in homes all around the world to provide good water pressure to residents.

The fact that you can take a shower on the second floor of your home is due to the water pressure provided either by the city or county where you live, or due to a pump you have on the water system at your house. Let’s talk about how you can use these methods at your cabin whether it’s off the grid or not.

Ben in Montreal is having trouble getting wet in the shower.

Often water pressure will decrease in a system when you have old pipes that are slowly collecting calcium and other minerals on the inside, closing down the diameter of the water flow. In a serious case, simply putting in standard new piping will make a world of difference.

If you already have good 1/2inch copper pipes and the flow works everywhere except that upstairs bathroom, many plumbers will recommend installing a special 3/4" line to that bathroom. This basically gives this room priority over the rest of the house. The primary draw back to this technique is that a 3/4 inch pipe holds more than twice as much water than a 1/2 inch pipe -- hence requiring much more hot water out of the hot water tank just to get to the shower, and then much more water in the pipeline that will eventually cool down wasting energy....

Turn off the water to the shower.

Remove the handle cover (it should pop off)

Remove the center screw (usually phillips head)

Remove the retaining clip holding cartridge in - you can use a pair of long nose piers or a small screwdriver

Grab the cartridge with a pair of pliers and pull straight out. It may require a little force - there are O-rings around the cartridge to keep it from leaking.

Check the cartridge bore (the hole where the cartridge was removed)

Clean any debris or scale - lime away or CLR will work

Apply a little bit of soap around the new cartridge to help it slide in easier. Push it all the way in and make sure it is seated. Re-install the clip (you should have received a new clip with the replacement cartridge)

Turn the water back on a check for leaks

If OK, reinstall the knob screw, and...

Low water pressure can be one of the most annoying, though not truly critical, problems a homeowner has to deal with. It can make proper rinsing after showers difficult and cause a number of other inconveniences. To increase water pressure, a number of steps can be taken. However, trying to find the root problem is recommended.

The first step needed to increase water pressure is to determine if there are any major plumbing problems. These could include leaks or blocks in the pipes. This may also be the most expensive step in the process. If no leaks or blockages can be found, it may be that the municipal system simply has weak flow in your area and the only option may be to treat the symptoms.

In some cases, the water pressure problem may be limited to a particular sink or shower, especially those with aerators. Over time, sediments can build up on these aerators and clog them, making the flow weaker. In these situations, the best option is to take off the aerator,...

Believe it or not it is very common that the Plumber doesn’t have enough knowledge of what the water pressure should be in the house.

To give you an indication and a little more knowledge of how the water pressure works. We have taken it upon myself to give you an insight of how the water pressure should be.

Water Pressure

Here is one of the theory’s of why the water pressure is strong or poor. It is known that the more the weight of water, the higher the pressure as shown in the picture above.

If you are a Plumber then you should know, when finding a storage tank in an airing cupboard for example, an apartments or standard houses. You will find that fillling a bath can take about half an hour sometimes.

If you live in a house where the tank is in the attic above the 1st floor and the bathroom is on the ground floor, then your bath should fill within 5 minutes.

The saying goes, the wider the pipe, including the outlet, then the quicker the...

Ever taken a bath or tried to fill up the sink to wash dishes with low water pressure? It’s the worst. It takes forever and you know it doesn’t have to be that way. What can you do? Here are 5 tips to increase water pressure. If these don’t work, well…it might be time to call in a professional. Learn more about how a constant pressure system can help.

Check the water meter. – Yes, you would assume it’s all the way on, but things happen. Be sure it’s operating at full strength capacity. Check your main shut off valve at the street. – It’s not unusual to have work done and then slowly let water back into the pipes to ensure everything is okay. Sometimes it gets left in that position. Make sure it’s full on. Check the pressure regulator. – Each home has a pressure regulator on its pipes to ensure water isn’t rushing into your home too quickly. If too much pressure is built up it can harm or blow our fixtures and faucets and possibly pipes. Pressure regulators make sure the 100 PSI...

If you've recently moved out of the city, where a home's water pressure is typically 60 pounds per square inch (psi), it might be disappointing to find a drop in water pressure in your new country home. When you turn on the shower and have to run around inside it to get wet, increasing the home's water pressure takes center stage. To improve the well water's pressure requires a few quick adjustments to the pressure tank and pressure switch.

Turn off the circuit breaker that supplies power to the well pump and pressure switch. This critical step ensures your safety as you work on the system. Both the well pump and pressure switch usually operate on the same circuit.

Locate the air-fill valve atop the pressure tank. The pressure tank sits adjacent to the well pump. The air-fill valve is similar to the valves found on tires for adding air, though the air-fill valve on the tank is metal.

Attach the tire pressure gauge to the air-fill valve to get the pressure...

Hello, everyone. I'm Joshua Clement, and today I'm going to talk to you about how to fix no water pressure in your hot water heater. Now there's only a couple things that will prevent the water from flowing through your water heater and reducing that water pressure. One of those is your shut off valve. Your shut off valve is designed so that way you can shut off the water and work on your water heater. A lot of times there's corrosion that is created because of the walls on the shut off valve that actually slow down your water pressure. One thing you can do is actually move your water shut off valve back and forth to break loose all that sediment and corrosion that's on the inside of the pipes. Another thing you can kind of knock it a little bit to help vibrate that stuff loose. Something else you want to check is all of the main lines coming into your water heater. Make sure that there's no shut off valves there, that have been twisted a little bit or have...

Have you ever had your shower reduced to a trickle because someone started the washing machine or turned on the dishwasher? This nuisance happens because your private water well system or utility pipeline doesn’t have enough water pressure.

You don’t have to coordinate your shower with household tasks. Constant water pressure is attainable, and it not only makes life more comfortable but also helps water softeners, iron removal devices, and other equipment work more efficiently to provide safe, potable water.


Water flows out of taps because of pressure in the water system. For most well systems it is a well pump that provides the pressure that makes the water flow. Different pumps have different flow capacities, as the overall rate of flow is directly related to the pump capacity. If your household has a 10-gallon per minute demand, there will be trickling water if the pump will only supply five gallons per minute. A pressure tank in a water system is...
