Pic not mine. but boiler is very similar.Landlord has dementia and overfilled the building's boiler. I have permission to do work on the boiler in his absence (for cheaper rent)Heat has not worked as far up as my floor since it was overfilled, due to water making it's way into the supply lines. I've only managed to purge one radiator of all of it's water so far because it's high up off the floor. The rest are moronically close to the floor and purging just results in water everywhere.I *could* spend hours soaking up water with a towel and wringing it out, but I feel like there *has* to be a better way to do this.I was considering disabling the boiler, opening the radiators at the top floor to vent, and then letting water into the drainage basin via the main return line's bung.But after thinking about it, I'm not sure if that works. and I don't think I can just drain the main supply line, especially since that means disturbing asbestos insulation.Any advice on the situation would be helpful
>>2870219>I was considering disabling the boiler, opening the radiators at the top floor to vent, and then letting water into the drainage basin via the main return line's bung.This is the common-sense way. I don't understand how you would disturb the asbestos insulation, you just pop the bung open and collect the excess water in a bucket or two. How much extra water has been put into the circuit?
>>2870346> This is the common-sense way. Okay so my initial guess was correct then> I don't understand how you would disturb the asbestos insulation, you just pop the bung open and collect the excess water in a bucket or two.The supply lines are wrapped in asbestos, while the return lines are completely exposed. I can safely open the bung on the return line, but to pop open the bung on the supply line I have to reach into a gap in the insulation that's about a hand-width in size.> How much extra water has been put into the circuit?All I have to say is that it's a lot of water.
>>2870219Just open the security overpressure valve until the pressure ist at a normal Level again.
>>2870596Doesn't have one. Closest I have is a little lever I push on with a heat-resistant glove
>>2870619Impossible. If it didnt have one, your radiators would look like picture related.
>>2870622> Impossible. The system never goes above 4 PSI, my research tells me that's because it's a gravity-feed system and relies entirely on thermodynamics to generate flow. Hot steam go up, cooler steam come down.> If it didnt have one, your radiators would look like picture related.I extremely doubt 4 psi is going to blow up a cast iron radiator that's two-times my weight, and four-times my age.
