Low water pressure is an issue that plagues many homeowners. It can affect old and new houses and can be difficult to remedy. The good news is, you don’t have to put up with it. Installing a water pressure pump can significantly improve your troubles. This article discusses what a water pressure pump is and how you can easily install it in your home.

What Is a Water Pressure Pump?

Also known as a water pressure booster, water pressure pumps to increase the pressure of incoming water from your well or city water supply. As water flows into the tank, compressed air pressurizes the output, giving it the boost needed to flow throughout your house.

While shopping for a water pressure pump, there are a few key features you should consider. You will want to make sure the tank and the motor are large enough to make an impact on your home’s water pressure. Consider how the water pressure pump operates, such as manual and automatic shut-offs. Some water pressure pumps come equipped with different modes, allowing you to choose how much water and energy you conserve. Finally, you may want to consider a water pressure pump with quiet noise ratings, depending on where your water main is located.

7 Tips on How to Install a Water Pressure Pump

Tip 1: Determine the Source of Low Water Pressure

Before purchasing a water pressure booster, you should make sure your home’s low pressure is not caused by more serious issues. Clogged pipes are a common cause of lower water pressure in older homes. This can be caused by years of use, pipe corrosion, or sediment. If low water pressure only affects a small section of your home, you may have clogged pipes. Other factors, such as leaks and building height, may attribute to your low water pressure as well.

If you live in the city and your neighbor’s house has low pressure, the issue may be with the city’s water distribution. The city can usually provide a reading of your home’s incoming water pressure. If the reading is below 30 PSI, purchasing a pressure booster pump could be very beneficial.

Tip 2: Check Municipal Plumbing Regulations

Before installing your pressure booster, you should check with your city for local plumbing laws. Some cities require work to be completed by a certified plumber. You should also check to see if the city requires any additional fittings for your installation, such as a dual check valve or pressure reducer.

Tip 3: Prepare for the Installation

Before beginning the installation, ensure that your water is shut off. Drain all the water in your pipes, even in your water tank. Leave your faucets open, though. You will need to release air before and after the installation.

Tip 4: Reroute Water Main Pipes

Installing your new pressure booster will require a few cuts to the water main. If you have a water softener, be sure to position the pressure booster somewhere between the softener and the water meter. Most water pressure pumps also require indoor installations, away from inclement weather.

Line the pressure booster into its permanent position to measure where you should make your cut on the water main. Before making your cuts, be sure to clean off the pipe with emery paper. This will ensure that the fittings can adequately grip the pipe. Be sure to make the cut into the exact fit, taking into account any 90-degree angle joints. Make an additional cut where the booster output pipe reconnects to the water main.

Tip 5: Make Sure You Install Or Reinstall Your RPZ Valve

I don’t know of any municipality that doesn’t require some sort of backflow prevention device on a home are commercial building attached to it. Make sure you reinstall the RPZ. If you don’t you’re putting the city water supply at risk.

When you install the pipes and fittings, it’s a good idea to install a pressure gauge in the outlet pipes, if your unit isn’t already equipped with one. This allows you to check the PSI going into your house and adjust accordingly.

When you’ve installed the pipes and accessories, either wrap the threaded ends in Teflon tape or pipe joint sealant before soldering. Since you’ll be soldering the fittings, you may want to use compound instead of tape.

Tip 6: Call an Electrician (If Necessary)

Check your owner’s manual to determine the electrical requirements for your new pump. Most units require a dedicated GFCI circuit. It’s best to employ an electrician to install the circuit accurately. If your unit comes with a ground cord, and you already have a GFCI outlet, you can simply plug in and move on.

Tip 7: Test the Water Pressure

Once you’ve completed the installation, turn on the main water valve. Let any excessive air run through the pipes for a few minutes before you turn the faucets off. Check the water pressure with the gauge you installed or the gauge that came with the unit. Depending on the size of your house, you will want to be around 50-69 PSI. The absolute maximum should be 75 since 80 PSI could wear down your pipes.

Bottom Line

Low water pressure doesn’t necessarily mean you can’t take the perfect shower you’ve been craving. If you’re suffering from an unsatisfactory well pump or city water delivery, a water pressure pump can end much of your inconveniences. With careful preparation and cutting, it’s easy to install your own water pump. Go to your local home improvement store today and make the best out of your water supply.
