Removal of the Old Pressure-Balancing Valve

Removing your old pressure-balancing valve from the faucet is the first step in replacing it with a new one. Before you begin, make sure that you have turned off the water supply to your faucet.

Start by removing any decorative caps or screws that may be on the faucet handle initially. Then unscrew the retaining nut and pull out the valve cartridge. Be careful when removing the old valve as there may still be water present and some parts of it are delicate and breakable.

Once removed, take note of any markings or positions that were on the old pressure-balancing valve as this will help you install your new one in the same way.

Detailed steps on how to remove the old pressure-balancing valve from the faucet

The pressure-balancing valve is an important safety feature, as it prevents dangerous fluctuations in the water temperature when one faucet is opened and another is closed. If your pressure-balancing valve has become faulty, it will be necessary to replace it in order to maintain reliable temperature control. Here are the detailed steps for safely removing and replacing an old pressure-balancing valve from a faucet:

  1. Turn off the water supply valves connected to your hot and cold water lines and also turn off your main house water valve in order to prevent damage from uncontrolled bursts of high-pressure water.
  2. Using an adjustable spanner or wrench, remove the handle nut located beneath the faucet head by turning it anti-clockwise until it becomes loose enough to pull away easily. Once removed, you can then gently pull away both the handle itself, as well as its associated escutcheon plate which will be underneath it.
  3. Then using a Philips head screwdriver or drill bit, unscrew the clamping screws which will be located around the rim of your old pressure-balancing valve at its connections point with each of the hot/cold pipes leading up into your faucet head – these should come loose fairly easily so ensure very gentle removal is practiced here so as not to damage any adjacent system components such as other plumbing hardware or even pipes themselves. Once free from its connections point proceed by manually lifting out and away from your system with minimal force used only if absolutely necessary at this juncture.
  4. Gently scrap down/off any old pipe sealant located around each of its coonectiva points – taking care not to drip any debris in/around other system components here.
