How do I release the pressure on my Baxi boiler?

How do I release the pressure on my Baxi boiler?

If the pressure goes above 3.0 bar, you will see water coming from the pressure relief valve (usually on an outside wall). You can reduce the pressure by bleeding a radiator or draining some water out of the system using a drain point, usually found underneath a radiator.

Where is the pressure relief valve on my boiler?

#3 – Check the safety discharge pipe This is called the Pressure Relief Valve Discharge Pipe (or commonly called the ‘P.R.V. ‘) It’s a small pipe, which can only be seen on the outside wall of where the boiler is installed.

How do I fix a leaking pressure relief valve?

Use a pipe wrench to unscrew the old pressure relief valve. Wrap Teflon tape around the threads of the new valve, and screw it in until tight, orienting the overflow pipe opening away from the tank. Reattach the relief valve drain pipe using Teflon tape on the threads.

Why is my pressure relief valve leaking on boiler?

If the system pressure is 30 psig and the relief valve, rated for 40 psig, is leaking, the relief valve is most likely defective. The most common causes are leaking gauge glass fittings above the water line of the tank, excessive system pressure, undersized tank, or the tank has a leak above the water line.

How do I adjust the pressure relief valve on my boiler?

The lock nut can be loosened if you remove the fast fill lever cap. Slowly turn the adjusting screw clockwise until the system gauge shows the pressure required. The adjusting screw has to be turned counterclockwise to lower the pressure.

Why is the boiler pressure relief valve important?

The pressure relief valve of your boiler is a very important part of your heating system. This is because it is a safety valve that protects your heating system from building up too much pressure. When that happens, you are faced with leaks or even the possibility of your heating system blowing up.

What causes a pressure relief valve to leak?

3. The Expansion Tank Is Water Logged. This part allows water in the boiler to expand. Over time, it becomes logged with water or air starts to leak out of the tank, and when this happens the pressure relief valve will start to leak.

What can I do to lower boiler pressure?

The best way to reduce the pressure in your boiler is to bleed the radiators. Before you start, make sure your central heating system is switched off. You’ll need the radiators to be cool enough to handle. Some modern radiators can be bled with a screwdriver.
