CH pump adaptors

[Brightonguy]

I do not like the idea of using the off the shelf combined isolator and pump adaptors. These always leak and rarely shut off when replacing pump. They also restrict the flow quite a bit as well.

Can someone point me to adapters that go from 1 1/2" (the pump size) directly to 22mm copper with integral isolators. I intend to use 22mm full flow ball valves as pump isolators.

The ball type pump valves leak and do restrict the flow.

Use gate type pump valves and u won't have a problem

The gates never shut off properly. The aim is to use two in-line full bore valves to isolate a pump, check valve and flow switch. At a push, I could get the gate valves and tighten them up so they are not used or leak.

Just use plain pump unions with a MI x Cu and lever ballvalves

That is what I have in mind but can't pin them down. BES do not appear to have them. Or do they?
