Hoping someone can guide me.
I fitted a new shower cubicle with a Salamander pump yesterday. I incorporated the pump because the header tank is only about 600mm above the shower rose.
The pump is situated at the foot and at the side of the hot water tank, which sits on the same floor as the shower cubicle and is about 1.5 metres away.
When I commissioned it yesterday afternoon, going through the instructions as per Salamander pump, I cleared out any debris on hot and cold side of pump by flushing water through from supply, catching in a bucket. Then refitting filters.
Then fitted the feed pipes to the shower and hot and cold water ran fine to shower although slow.
Then ran shower on full cold, then full hot for about 6 seconds each, three times, with pump running, using the electric feed to stop and start the pump and change the temp setting each time.
Then I ran the shower as normal, checking main rose, hand-held rose and massage jets. everything was working hunky-dory. Temp/on-off tap working fine also.
After a couple of hours, after clearing up, etc, I came to use the shower - no cold water! It wouldn't flow without the pump, it wouldn't allow the pump to run, and if I turned to hot water only then slowly turned back to central position or cold the pump stopped.
So the hot water runs without the pump, albeit slowly, and starts the pump OK and then decent pressure, but the cold water: nowt, nothing, with or without the pump. The pump doesn't run, obviously, if the temp regulator is turned even slightly onto the cold.
I'm hoping to take a look later today, otherwise it'll most likely be Monday.
I assume, that either, there's some dirt blocking the cold, perhaps at the filter on the pump, even though it was flushed out.
Or I've somehow got an airlock in the cold water supply, but it's difficult to see how.
Or somehow the cold water flexible pipe has been crushed when I pushed the cubicle back to the wall, even though there is plenty of space and it's difficult to see how.
I have connected the hot and cold to the correct sides of the temp mixer valve as indicated by the instructions.
