Shower pump blues

[Drippydan]

Hi - I replaced my shower cubicle, its the same pump (dual) - gravity supply - just the cubicle has changed. For some reason the pump isnt engaging at all and Im not getting any flow.

Any ideas please? If its an airlock how do I find out and what do I do?

All best and thanks for looking.

Which pump / does it have a priming screw / do you have a vent anywhere / does your shower have a hose?

Hi - thanks for getting back to me. Its called a "newteam deluxe" and I cant see any kind of primer screw.

*UPDATE* - I can get a trickle to flow through the shower head, cold only, and the pump actually engaged for about 5 seconds last night. By the time I got my socks off though, it had stopped again.

It has a hose, all in tact and theres no vent. Both tanks are massive and about 30 foot above the shower (I live in an old mortuary), with dedicated pipes and no junctions.

If I disconnect the whole shower gubbins before the pump and valves, the water gushes out of the shower pipes. The valves are brand new.

I checked the elecrics and all wires/fuses are ok.

It could be that pipework between pump and shower takes a route that traps air. There are ways of drawing it out.

One is to use a wet vac (at the shower end).

If you have a bath filler, then another is to use the cold flow to that to push hot water through the pump and out of the shower.

Yet another is to cross-connect the hot and cold washing machine appliance valves (if you have one) - to do this you'd need to cap the DHW vent over the cold storage cistern, and open the shower valve before allowing the mains to pressurise the hot supply.

Hi - I tried the cold flow through the hot and it worked!

Thanks very much indeed for your help, I owe you one. I better go and have a shower now, I haven't had one for a week.

all best - have a good easter
