Hi folks,
Have had a problem with a power shower for some time. When we start the shower, it will occasionally start to whine in increasing volume and pitch until the flow stops. If we turn the temperature dial all the way to cold, the shower pump (I'm assuming) returns to its normal sound, flow starts again. We adjust the temperature back to normal, pump starts to wind up again, flow stops, rinse and repeat. Eventually, it will work properly and we can finally get a shower.
Have had several plumbers attempt to fix this problem. Two have been adamant the shower is faulty, so we've had 3 power showers at this point. One changed pipes and the hot water cylinder, one said it was fine (because maybe half the time it works fine) and charged us for nothing. The problem is exactly the same after all this expense.
So we've had another plumber look at it, and he's suggesting the shower should never have been plumbed as it is. It's currently plumbed up from the hot tank, across the attic (less than 2m), and down to the shower. His suggestion is the hot water is getting airlocked and needs to be plumbed down, under the floor and up to the shower. Airlock sounds possible I guess, but he's quoting roughly £1000 to correct this, since it means ripping up floor, tracking wall, removing shower enclosure etc.
So I was wondering if we could get a broader opinion on the problem before going to more expense? Sounds like it could be possible. Have attached an artwork masterpiece trying to show the current layout.
Many thanks,
Baps.
