Discuss Cowboy victim? Wrong flow direction WUFH in the Water Underfloor Heating Installations area at PlumbersForums.net

Hello all. Thanks in advance for any help you can offer with this.

Recently had an extension put on the side of the house for a new living room with wet UFH. Rest of the house is on rads running from a gas combi boiler.

I have a feeling that the pipe work has been connected to the UFH pump the wrong way around. This would not surprise me as the sub contractor my builder used was not far from useless.

I've attached a pic showing the direction that the water is trying to flow through the system, but it seems odd to me that the pump would be situated where the water exits the system. The pump makes no noise at all, so I assume it's not activating, either that or it's really bloody quiet!

The 'return' is never more than luke warm, but the flow pipe is too hot to touch.

Am I seeing a problem that isn't there, or was this plumber actually more useless than I thought he could be?

All advice appreciated.
