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.
Pros: Much quieter than my previous pump (Salamander). Great water pressure. Seems very sturdy and the plumber who fitted it said these were very reliable. Also quite a bit smaller than the Salamander pump I had before.
Cons: Quite heavy if you have to transport it anywhere (I had this delivered to work and had to lug it home on the train).
Neat, solid whole house pump. Quiet performance and great water pressure. Very happy with this, especially as managed to buy while on sale.
Pros: High quality, Very quiet, Good power, Great Price
Cons: Only comes with 22mm fittings so be prepared to re-plum your pipework if you are replacing a pump with 15mm fittings.
Pros: Very quite
Cons: None at present
Old easi-boost pump broke down reviewed this pump and so relived I did as now have quiet pump needed a little bit of re pipe arranging but well worth this
Pros: Easy to install, Functions well, Looks the job!
Cons: Lack of in-built isolation valves might be enough to make someone go for an alternative unit
This pump was straightforward to install, it looks good, and functions very effectively.
Even the Grundfos packaging is well designed!
It comes with 4 push-fit 22mm flexible adapters. These don't have integral isolation valves, but this wasn't an issue for me because my installation already had adequate means of isolation and drainage.
The brass construction and continuous rating make this unit more expensive than plastic alternatives, but hopefully this will pay off in the long term.
Pros: Quiet. Reputable brand. Solid build. Good performance.
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!
Pros: Easy to fit
This pump was purchased to replace a Bristan HYPUMP100 which is no longer available, it is the same size and and was fitted without having to alter the pipework.
The pump is very strongly built and should last for years. It is very quiet in operation unlike the pump it replaced and provides a good pressure for a shower. An excellent product
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
