I may have mentioned this before but our CH boiler is situated in the bathroom airing cupboard on an internal wall with the flue coming out the top and through the roof. Currently the Pressure Relief Valve outflow just disappears under the floor and vents into the floor space. This has not been a problem so far with the only venting occurring when I accidentally over pressurised the system.
I believe that it is a requirement now to be able to see if the PRV is venting. Short of creating a convoluted route lifting floor boards to get it outside which is not going to happen. To avoid freezing issues I have re-routed the condensate pipe so that it runs through a running trap before it connects to the stack which again is internal. My question is can I also vent the PRV outflow into the 40mm section of the condensate pipe which runs just below the PRV pipe which to me seems the logical thing to do?
Just asking in case there are any gotchas.
