The pressure-assisted toilet is an innovative unit that many home owners choose to install in their houses or apartments. Compared to traditional toilets, these units do not use only water to flush the waste, but instead, work under pressure. This method is effective because the pressure speeds up the flow of water and facilitates flushing and cleansing. However, as with all mechanisms, these toilets might get broken. If your toilet is not functioning properly, the culprit is often the pressure regulator inside the toilet tank. Don’t panic, however. Diagnosing and repairing a pressure assisted toilet is comparatively easy in contrast to most plumbing projects. Here is a simple guide on fixing your pressure assisted unit with just a handful of instruments.

Step 1 – Identify the Problem

Make sure that the problem really exists. Just because the toilet doesn’t flush right away, it does not mean that the unit is broken. Wait for a few minutes until the pressure gets back to normal before you flush again. This check will eliminate the need of buying a new pressure regulator, wrongly presuming that the toilet is broken.

Step 2 – Remove Water from the Tank

Shut off the connection to stop water from flowing into the toilet. Perform this action by closing the shut-off valve.  Flush the toilet to release pressure from the tank, emptying the water from the toilet bowl. You may place a wash-basin under the shut-off valve to prevent water from spilling all over the floor. Stopping the water flow is important as you don’t want to work under pressure.

Step 3 – Break the Water Supply Connections

Disconnect both water connections to the supply source by unscrewing the nuts that hold them in place. Remove and lift the tank off the bowl to get an idea of what went wrong.

Step 4 – Remove the Defective Pressure Regulator

Use the pliers to remove the spud nut and once again to unscrew a second connection at the bottom of the tank. Once the nuts are unscrewed, remove the pressure assist unit by sliding it out of the tank. You can perform that easily; just abstract it by pulling the power regulator down. Then, cut the pressure regulator close to the hose clamp using utility knife. In most cases, the pressure-assisted toilet is not working because the pressure regulator is defective and the pressure is too low.

Step 5 – Install the New Regulator

Install the new pressure regulator once you have removed the faulty one. Place the new stainless steel clamp and tighten using a screwdriver. Next, attach the pressure-assist unit, bolting it to the toilet tank, and you are almost done.

Step 6 – Bring Back the Water Supply

Turn on the water supply and flush to test the performance of your new pressure regulator. You can flash once the tank is filled up with water.
