New Truma pump fitted but no water flow to taps and no pressure.
It comes out of the drain valve ,which is past the NRV and hot tank makes a bubbling noise ...
Any suggestions please ?
You don't say what caravan you have so following can only be a guess !
You say that water is coming out of the drain valve which suggests that the valve is open. It should be shut when filling the hot tank.
The water will keep on "bubbling" for quite some time until the tank fills.
Suggest you shut the valve and have another go but let the pump run for several minutes.

I managed to get it working by shutting off and then draining the system and refilling.
( the water flows through the drain valve proving pump is working)
Not sure if that’s a fix !
Many thanks for responding DaveS1
