Pumps, pressure reducing valves and showers

It is a quick fix, personally, would go for a separate pump down at 1 or 1.5 bar and just a low to medium flow rate - you don't need one that can push out 35 litres/minute

 

I'd run this past Salamander first - tell them you want to reduce the pressure to these two items, and whether a PRV set to, say, 1.5bar and located in the supply from the pump to these bidets will affect the operation of the pump in a not good way.

If they say it's ok, I think that's the route I'd take - try and avoid adding extra pumps if possible.

What happens if you just turn the 'tap' on the bidet down? Can't you adjust the flow that way? Or does the Salamander not fire up unless it has a decent flow first?

(Lawd - I hate pumps...)

If the pump does fire up cleanly with the bidet tap only opened a touch - enough for a gentle cleanse... - would a simple solution be to tweak down the isolating valves that feed the bidet? Assuming there are valves fitted? Eg - turn these isol valve down to a half flow, and then the bidet's own taps can adjust the rest.

I have a horrible feeling that such a powerful pump will be less sensitive to such gentle flows, tho', so the taps need turning on quite a way before they fire?

 

Cool - thanks for the feedback

(If you need to, these pumps sell easily on eBay - especially if you state how new it is (and still under warranty) and the genuine reason you were replacing it (too bludy powerful!)

That's if your plumber doesn't do the decent thing - it was his mistake after all...
