Hi guys. got a problem with a water pressure leak whenever my central heating is on. Central heating was laid and installed in 2012. To fill you in, a year ago I had a slow pressure leak and had to repressurise the boiler every few weeks until eventually it was once a week. I had a gas engineer a year ago put sealer into the system and that held the pressure fine for a year.
Now the bar pressure goes down from whatever I set it at, usually 1.5 bars, to 0.3 after just a couple of hours of heating along with an F22 message flashing on the screen saying 'safety switch off, no water pressure'.
I had a different gas engineer come over a couple of weeks ago to service the boiler (Vaillant Ecotec Plus 831) and he inflated the diaphragm in the expansion tank as he said it was flat. He reckoned that should fix it. Well it made no difference. He came back a few days later, re-checked the boiler, said it's absolutely fine and put some sealer into the system. While he was here he went into my front room to check the radiator and we had a catastrophe, the valve broke away from the radiator followed by flooding from the radiator and water peeing out of a crack in the upright copper connecting pipe that the valve sits on. Fortunately I have laminated floor and not carpet. He stopped the flooding though.
Then I had a plumber come over couple of days ago to replace the radiator as he was unable to get the broken bits out of the old rad. The heating is all working but the pressure is still going right down to F22 after less than 3 hours heating. I wanted to try a process of elimination. I turned off all but one radiator today and just ran that rad. Pressure still went down and the F22 returned, so I repressurised again.
I could continue with the process of trying each radiator, but I think this leak is affecting all of them. I called the plumber and he suggested I get a company in with a thermal imaging heat detector to pinpoint where under my floor the leak is. And then he said he could come back and fix it. But of course it looks like flooring will have to come up.
It's a ground floor flat with concrete floor under porcelain tiles in the kitchen and adjoining bathroom, and then floorboards under laminate flooring in the hall, bedroom and front room.
I've already spent £460 with the gas engineer and plumber and haven't really gained anything. I need to get this sorted but wondered if you think I should get a thermal imaging company in?
I called my buildings insurance broker last week and was told that I'd be covered for repairs and making good on floor replacement, but I have to pay the first £400 excess. What do you recommend I do? The whole thing is really ******* me off now because it's expensive and I'm dreading pulling flooring up.
It's easy enough for me to repressurise the boiler, takes a second, but every time I do that, I'm washing away the rust inhibitor.
