Rmichie Posted May 31, 2023 Author Share Posted May 31, 2023 Thanks Tony - is that normal to have that then? Link to comment Share on other sites More sharing options...
BotusBuild Posted May 31, 2023 Share Posted May 31, 2023 It's part of the safety features for closed hot water systems - yes, it is normal (and looks different depending on which plumber fits it 🙂 ) Link to comment Share on other sites More sharing options...

TonyT Posted May 31, 2023 Share Posted May 31, 2023 It’s been fitted with round head screws. Clearly a decent install, as it’s not the gold screw countersink 1 screw does all brigade. Link to comment Share on other sites More sharing options...
SteamyTea Posted May 31, 2023 Share Posted May 31, 2023 Staining bar, used to be very common in Morrocan toilets. Or was that just my experience. Link to comment Share on other sites More sharing options...
ProDave Posted May 31, 2023 Share Posted May 31, 2023 It is correctly behind a cage as when it blows off it could be near boiling water coming out. Link to comment Share on other sites More sharing options...
saveasteading Posted May 31, 2023 Share Posted May 31, 2023 Explain please as I have never seen this. A primitive safety valve where the joints are weak so that it comes apart? Link to comment Share on other sites More sharing options...
TonyT Posted May 31, 2023 Share Posted May 31, 2023 No like a gas boiler flue,l with a cage at a certain height there to stop damage/ potential vandalism Link to comment Share on other sites More sharing options...

A primitive safety valve where the joints are weak so that it comes apart? The safety valve (actually two, over pressure and over temperature) are on the hot water cylinder . This is where the discharge pipe leads to, it is just an open end of pipe, in this case turned back to face the wall. If the blow of valves open, then it may be very hot water existing this pipe, so it is put behind a cage, and it must be somewhere visible. 1 Link to comment Share on other sites More sharing options...
saveasteading Posted May 31, 2023 Share Posted May 31, 2023 Ok I see that. The bottom outlet is a few mm off the wall, so it splatters scalding water against the wall, safely and visibly. I recall now seeing them in copper. An oversized pipe seems wise to reduce the pressure. Link to comment Share on other sites More sharing options...
