Known hard water locations are also far more likely to have government programs that are intended to help homeowners pay for these upgrades. This is probably also an issue of volume, and it’s likely not just low water pressure in the shower only, but throughout the house as well. When a toilet flushes, it draws cold water from the house’s plumbing to refill the tank. The water heater that supplies the shower with hot water draws in cold water as well and then heats it before sending it out into the home.
In many homes, there are two major shutoff valves controlling water to the home. The first is the water meter valve, located right next to the water meter on the main city supply pipe serving your home. Normally, you will not use this valve, as technically it belongs to the water company and is typically used only by water company personnel. But if your water pressure is low throughout your house, especially after some work has been done on your plumbing system, it's possible that this valve is not fully open. In many homes connected to a municipal water supply line, two main valves control the water flow into the house.
Water Valve Issues
In this case, a local well and pump expert can come to remove the pump, flush the well, and clean or replace the screen as well as any other components that are causing problems. Having a clogged well screen may indicate your well needs a better seal. Of course, fixtures aren’t the only things that can become clogged by mineral deposit buildup from hard water.
Turn off washing machines, sprinklers, refrigerators with ice makers, and dishwashers. When you test the pressure with a gauge, you are measuring the static water pressure; if water is moving anywhere in your plumbing system, it may result in a false low reading. There could be a gravity issue, which means that a booster pump is most likely necessary. Also, check to make sure that any control valves are completely open, as a half-shut control valve can reduce flow, which ultimately kills water pressure. Whether it’s installing a home water pressure booster or simply opening a half-shut valve, the tips in this guide will help increase water pressure in your home. While extreme cases require that you replace sections of pipe, you can handle some clogs on your own.
The Most Common Problem – Obstructions
In any of these cases, the pressure loss will be temporary. But when the water does come back online, it will definitely kick up sediment, which can clog supply valves and faucet aerators. Be prepared to flush them if the pressure seems low when the water comes back on. Fire hydrants can freeze or fill with sludge, so cities typically flush them semi-annually to ensure they’re clear. This can cause serious, though temporary, water pressure issues in the houses down the line.
To determine the problem, you first need to know what type of system you are connected to. Namely, if you are on a municipal system, and you experienced a sudden loss of water pressure, then there’s not much that you can do.

Low Water Pressure in House All of a Sudden – Causes and Fixes
However, if it’s one or a few fixtures that seem to have a low flow, you may want to check out the fixtures. Low cold water pressure with normal hot water pressure is uncommon, but tracking down the issue isn’t difficult. Because the hot water pressure is fine, you know that the cold water must be working properly up to the point where the water supply branches off to the water heater.
Low or inadequate water pressure can be caused by an array of factors. Some, such as faulty fixtures, are pretty easy to identify even for novice homeowners. While others, such as corroded piping, are massive issues that require professional intervention and a full remodel of your house’s entire system. In some instances you may have to consider replacing your water service line going out to the street.
Get Better Water Pressure with Soft Water
But if you don't have a permanent gauge, it is very easy to do a periodic test with a standard water pressure gauge. For one, your well could be running dry, or the well pump could be on the fritz. Also, a half-shut supply valve or leaks could be robbing potential pressure.
You can probably find the meter valve in an underground box between your house and the street. Otherwise, it may be located in an interior area like an attached garage or basement or outside on a wall. Since there are different water pumps, it would be pointless to explain how to reset the pump. And, therefore, fixing this problem requires a professional.
Check for closed water valves, open valves that should be closed , and other issues that might affect pressure. If a specific sink, shower, or appliance is involved, the problem probably has to do with the control valve or supply line that feeds the fixture. Replacing a shower head might be the best option, particularly if your home has water flow issues to begin with. In a home with otherwise adequate water pressure, it’s not uncommon for one or two fixtures to trickle weakly when they should powerfully cascade. Here’s what you can do when you notice water pressure trouble with your shower, sink, or toilet. If the oomph has gone out of your plumbing, there are several things you can try before calling in a pro.
Again, replacing any valve on your main water supply requires the service of a licensed plumber. The plumber will coordinate with the water department to shut off the water further upstream. There can be other causes for a loss of water pressure or water flow after you have closed and reopened the main water valve of your home. These usually involve some mechanical failure somewhere in the system and should be diagnoses and repaired promptly. Determining the cause of your water problem is the first and most important goal.
Check the faucet if you only have low water pressure in a particular location. In this case, the source of the low water pressure is likely a clogged faucet or aerator. Run water in all faucets and showers in your home to identify if there is are one or multiple problem problem areas or to determine that all locations have low water pressure. There are a lot of reasons why the water pressure in your entire house could be low, and some are totally out of your control.
It’s important to have your water tested and your plumbing inspected if you suspect this is what is causing your low water pressure. If you specifically notice reduced pressure when using hot water, it could be that your water heater is struggling to produce enough for your home’s usage requirements. Unfortunately, fixing these pipes may require replacement depending on how much damage has been done. It’s important to catch this problem early, so if you visit friends and family and notice they have much better water pressure, it could mean yours needs to be examined. Get your water tested and invest in a water softener if your water needs to be treated. Most water pressure booster pumps run $200 to $400, though some are considerably more expensive.
