Central Heating

Have I got a faulty PRV or expansion vessel?

Anonymous user 03/03/2024 - 3.18 PM

Shortly after the heating comes on, you can see water drip through the Tundish. I am suspecting a faulty TRV or maybe it could be the secondary expansion vessel?? FYI, this is a Potterton Promax HE Store 115 boiler.

Are you a tradesperson and able to answer this question?

Could be either a faulty PRV or an expansion vessel. From experience, I would check the expansion vessel first.
