Hello, I am looking for some help please.
One of my Wife's clients has an issue with a leaking rad, He is receiving end of life treatment at home and he has a large medical bed that appears to have been pushed into the TRV, snapped the head off and damaged the pipe work. I went round yesterday to replace the TRV for them as their plumber cant get out for 3 weeks - His wife was really worrying as he needs the heating due to really feeling the cold.
Problem is that the pipe is all bent and dented from the impact of the bed and would seem that there is a hollow spot behind the olive causing the leak. I whacked off the boiler, locked all the other rads off in the bungalow and began to drain down, Assuming it was a combi..., only 10 mins later im still getting full chat pressure.
I am not a plumber, im a chippy that isnt scared of plumbing and would like to help this couple out.
What i want to know is this.
"How do i depressurise a Greenstar Ri system"
The Greenstar Ri, im now guessing is a heating only boiler and regulates its own pressure from a constant mains cold feed? - I cant see any filling loop nor a pressure gauge; as i am draining down the mains feed is topping it back up? I need to take the pressure out of the system to change the TRV and copper tail (need to get under the floor, niceeeeeeeeeeeeeeeeeeee) How do i do this?
I could whack the mains off to the house? but surly there has to be an easy way? I cant see anything under the boiler other than a grub screw type valve on a 15mm copper pipe - i suspect thats nothing and the mains feed IN will be on a header tank in the loft?
I assume there will be a header tank in the loft but cant confirm, just yet.
Please, no "get a a plumber in" comments.
Cheers muckkas/.
