Good day all, First and foremost i am not a boiler installer or gas registered, therefore i do not touch this element of plumbing, but i am after the correct advise regarding the following issue.
I have had a gas installer who has piped the PRV and condense discharge pipe from a combi boiler directly into a 35mm waste pipe which has been concealed within a false wall. Both of these connections are upstream of a basin waste connection, the condense flexi pipe is just pushed into the top of the 35mm waste pipe, and the PRV has been pushed into an elbow socket and siliconed in place! - all on the same run, and discharge outside into a gulley.
Now, my understanding is that the condense discharge should be run in 22mm plastic and if connected to an existing waste pipe, must be done so after the basin connection or alternatively direct to outside and terminate into a gulley of some form. The PRV must be 15mm copper and terminate on an outside wall with either a returned bend on it or one of those "button" type connections. I am currently in dispute with the guy because i am not sure if this meets regulations. He is saying that this is acceptable and conforms to standard. As i have NEVER seen it piped this way, could you guys please advise me of the correct way that these should be installed? Thanks in advance.
