How to Correctly Change Water Pressure Regulators
Just like other mechanical devices, a water pressure regulator can break as time passes, and once it is broken, it needs to be replaced right away. If the pressure at the taps is so low or excessive, or if the pipes seem to bang and clang for apparently no reason at all, it is likely that the pressure regulator is broken. Fortunately, you only have to follow the steps highlighted below if you want to change a water pressure regulator.
1. Find the regulator. You can usually find water pressure regulators near the main water shutoff of the house. Switch off water to your home and open all the taps in your home to empty the plumbing system completely.
2. Squirt penetrating solvent to the pressure regulator threaded connections. Let it set for some time, preferably a few minutes, to make the connections loose. Put a bucket under the regulator so water does not pool on the flooring or ground. You can surround the bucket with rags to ensure that the flooring stays dry.
3. Adjust a pipe wrench to secure the pipe, and fit another wrench to the big nut that leads to the pressure regulator. Secure the pipe with a wrench and loosen the nut using the other wrench. Holding the pipe helps to prevent it from becoming twisted. Twisting splits the pipe, which forces you to shell out money for another pipe. You may need to tug hard many times to make the connection come apart.
4. Remove the regulator. To do this, loosen the regulator from the opposite end first by rotating a nut or the regulator. Clean up water that might have spilled out, and then apply some cleaning solvent to all threaded connections. Wipe away contaminants using a dry rag.
5. Tape the replacement pressure regulator and the threaded connections. Have your new regulator installed in the reverse order of the way you removed the old one. Secure the pipes with a wrench to prevent them from getting damaged, and make sure to securely tighten the connections.
6. Close any open taps and switch the water on once more. Check the connections of the regulator and tighten it if you need to. Adjust the pressure settings on the brand new regulator following manufacturer instructions. Wipe away water that has been spilled.
It is not completely impossible for you to find another problem in your plumbing system while you do these tasks. If, while installing a new water pressure regulator, you do find a problem you cannot sort out yourself, hire a plumbing professional to help you right away.
