Hi im looking to make a 7 outlet manifold for radiators if that makes any sense, the rad pipe is 10mm and I've bought four, 4 port 22mm closed end spigot. Can i i connect two of them by open one of the closed end, capping one of the ports and would It need supporting as its under the joists and would be floating from the copper pipe otherwise.
All budget TRVs and lockshields seem to be 15mm.
Would a Push Fit Single Socket Spigot Elbow 90 15x10mm (HD4A/15W) allow me to connect a 15mm TRV to my 10mm feed/return pipes? (dropping down from the ceiling and emerging from behind the radiator)
Also, I'm guessing the TRV would come with a brass olive that I'd need to replace with copper?
Yes. Acidic value of this waste is not enough to affect the HepvO valve.
Yes, you may perform a 38mbar air pressure test for 3 minutes.
No, we would suggest that you install a pipe system called Trigon, which is used for this application.
No. Our suggestion would be to use a leadlock fitting (readily available in builders merchants), which is a compression fitting to connect lead pipe to copper pipe.
No.
No, as it may damage the pipe wall. If you need to cut into pipe without draining the system, it is recommended you freeze the pipe.
Yes, although you must ensure you use a minimum pipe size of 22mm. If you need to make a right angle, it is best you use a cold form bend rather than a 90° Hep2O elbow for less resistance.
Yes, this will have no detrimental effect on the pipe.
