With water, you have different valves to troubleshoot with. The first thing is to determine whether a valve is fully open. Depending on your location in the country, some valves, like the main house shutoff valve, can be the largest valve in the house and go all the way under the sidewalk. Call Rooter Hero Plumbing of Mesa to analyze your valve problem and any other problems you may have with your water pressure. When you need a plumber in Phoenix, we can be there quickly.

Is the Water Meter Valve Fully Open, and How To Fix It

The first thing you should do is check the water meter valve. This valve controls water flow into your home and regulates how much comes out of your faucets.

If the valve is closed all the way, this will restrict the water coming into your home, which will cause low pressure when you use appliances that require more water, like a washing machine or dishwasher.

To check this, open up the main water valve (usually located near your water meter) and see if there is an arrow on it pointing toward “Off” or “Open.” If there isn’t an arrow on your main valve, look for another indicator, such as an arrow painted on it or an arrow printed on a sticker. If there isn’t anything like this either, just try turning it until it clicks into place, indicating that it is fully open now. If it needs to be fixed, call a plumber immediately.

Is the Main House Shutoff Valve Open, and How To Fix It

The main house shutoff valve is open. If the main house shutoff valve is open (or partially open), no water will come out. This is an easy fix — simply close the valve. You’ll get immediate results! If your water pressure increases significantly, you may have a leaky pipe or other plumbing problem inside your home that needs to be addressed by a professional plumber.

Is the Pressure Regulator Failing, and How To Fix It

A pressure regulator is a device that reduces the water pressure in your home. It does this by slowing down the flow of water and then releasing it at a lower rate. This allows for consistent water pressure throughout your home and prevents damage to your pipes and fixtures.

A faulty pressure regulator can cause low water pressure throughout your home. If your shower head doesn’t feel like it’s giving out enough water, or if you can’t get enough hot water from the faucet, there’s likely an issue with your pressure regulator. To fix this, turn off all the valves in your home that supply hot and cold water to faucets, showers, tubs, and toilets. Then turn on one faucet at a time until you find where the problem is located (this may take some time). Next, shut off all valves, except one that supplies hot water to a shower or tub; then open all other valves again.

Do You Have Old Steel Water Pipes and How To Fix It

If your home is more than 50 years old, there’s a good chance that its pipes are made of steel. And if you’re like most homeowners, you don’t know when they were put in or what kind of steel they’re made of.

Steel pipes can be relatively flexible but tend to rust over time. This can lead to leaks and other problems that damage your home and make it difficult for water to flow through the pipes quickly enough. If you have old steel water pipes, consider replacing them with new PVC or copper pipes soon.
