Bypass Valve on S-Plan Installation CH system

[RayPooley]

Just a quick one folks.

Should there be a bypass valve at the ringed location in the attached picture?

Between the pump and the CH/HW valves?

Thanks

Depends on boiler manufacturers instructions.

Ok. I will check. Thanks

There is no explicit mention of bypass exclusion. There is an arrow on the pump that indicates flow from right to left from the boiler. But that boiler connection at the rear of the boiler that the pump is connected to is described as the Heating Return which would suggest the opposite flow. Confusing. So there doesn't appear to be a bypass valve. I'm guessing that the gate between the white Reliance valve and the HW tank is just an isolator.

Found it......

It's between the CH and HW control valves as opposed to before them. So it's all good.

If it has pump overrun yes should have an auto bypass

It does have pump overrun.

Need an auto bypass fitting then else the one you have is always open
