4/ 5

Pros: Pump very simply to fit. , Very quiet in operation.

Delivery was very timely and within days of ordering.
I picked this pump as I wanted to provide additional water supplies to 2 showers. One in the main bathroom and the other in the ensuite bathroom.

Installation instructions very clear.

I installed the pump in the airing cupboard next to the hot water cylinder, so the hot water inlet supply from the cylinder was easy to rig in 22mm copper pipe.
The cold supply came from the header tank above, via a straight run down the wall. The discharge pipes from the pump were vertically up to the loft space and over to the bathroom shower. I installed 2 off 22mm "tees" to branch off to the ensuite shower.

Cold to pump and hot and cold from pump all in 22mm speedfit piping.

This pump certainly makes a great difference to the showers as we now have "power showers" in both bathrooms.
I can most definitely recommend this to anyone seeking a similar solution to poor water flows/pressures.

4/ 5

Pros: QUIET AND SPACE SAVING.

Cons: I used this product in Ireland in Dublin found it very difficult to purchase metric fittings for the pump connections and found the parts very expensive. Only complaint which is trivial.

Compact very effective pump ideal for the 2 bar shower that it was fitted to. Easy installation would use this product again

5/ 5

Pros: Quiet. Reputable brand. Solid build. Good performance.

Cons: None

Really fast service from the web purchase. Well packaged delivery. Pump is so quiet! Bigger than our old cheap pump so needed to replumb the install to fit the old pipe configuration but no doubts we made the right choice!

5/ 5

Pros: Well made, very quiet running, great shower pressure.

Cons: Not entirely sure if this was from the pump or a connection but after it was fitted, for about a week after each use there was a very slight wetness under both impellers. I checked everything was tight, subsequently it stopped and is all dry now.

I wanted to change my old 1.5 bar salamander pump serving a single shower to an uprated pump to serve two showers. Having compared the specs; reviews and prices of various pumps I decided to go for the Grundfoss watermill Amazon 2 bar pump.
I was not disappointed, I could see immediately this pump was a well engineered piece of quality kit.
