Hot Water Problem

[pisteman]

Hi everyone, greetings from French Alps.

Please can you generous people help with a problem I'm having with the hot water system on my Sunlight MH - air/water is just spitting out of the hot water tap ( frost control ok + not venting outside ) . After refilling boiler + waiting for yellow light to go out on the Truma CP (E) classic control dial the same thing happens. Following Truma's advice last week they reckon it was the pressure release elbow on the boiler and fair play they sent one out free of charge in the post to me, I've duly fitted same today but problem still the same. Following some fault finding tests of my own I think there must be a non-return valve that's bust because after lifting the submersible pump out of the water tank immediately after use a flow of water exits the pump via the intake chamber.
My question is - where is the non return valve if installed in-line with the pipework or does the Reich 12v pump have one that's integral??
We are fairly new to this stuff but still having a brilliant time.

thanks in advance Peter+Cress

Is there an 'damper' fitted close to the pump? It will look like a large diameter pipe with an inlet and outlet. It might be faulty. Its job is to help seperate air out and make the flow even and not pulsing due to the way water leaves the pump

looks a bit like this me thinks

example fitted to top of pump. they do one with and one without a non return valve, fitted seperate to pump

Apologies guys what with getting access to tank + modern tech. I'm assuming the "dampner" is sitting above the pump

Thanks Phil - any idea what they are called/description. The flexible water pipe is 10mm or just google non-return valve for Reich 12v sub. pump?
