Mains booster pumps.

[Dangee]

Right, I’ve never fitted one (except breaktanks). House refurb to start this week. 25 mdpe incoming but 1.5 daytime pressure. No room for accumulator & pumpset. Single person. Very fussy (not a problem. Done all the families houses for years) 1 bathroom, need pressure. Salamander any good?? Cheap but is it worth getting something better?
Grundfos now do something similar. Double the cost but if it works / sounds better, all good. Advice please.

What's the incoming flow rate? Direct connection mains pumps will only pump to a max of 12 litres per minute

....... At a max of around 1.5 bar dynamic.
