Good afternoon, Hope the sun is shining with you all.

I would appreciate some advice regarding my connections to my UFH manifolds.

The pump and mixer valve are an Emmeti TM3 R Pump Set. There are 2 x 1” BSP connections for 22mm the supply and return pipes. The pump has isolation valves to the right on the manifold. My question is, should I put inline isolation valves in the 22mm supply lines, so if I ever need to change the pump set? That would save me having to drain down the supply lines that go all the way to the plant room, some 20m away.

Any advice would be appreciated.

  

Yes definitely fit isolators in flow and return, will save you a lot of grief if you need to change or replace anything.
