Rated 3 out of 5 by poor instructions Easy to fit. However instructions very very poor. No clear cut diagram. ..just speels of gumpf! Pump must be fitted with spindle Horizontal, otherwise it'll run dry. Instructions do not stipulate or stress this enough. Flomasta looks like it's Screwfix own brand..... 27 Feb 2016
Rated 5 out of 5 by Replacement pump Pump runs very quiet and I am impressed by the low power consumption. The leaflet explaining the way the pump works isn't too clear as It's all from small picture diagrams. The pump has 2 options for running it. Standard 3 speed option or auto which works as a continuous speed increase as dial is turned up. Working out which side of dial was which wasn't too clear. Also the way to orientate the pump wasn't easily understood. The pump seems to output a higher flow than my old grundfoss 15-50 too. I know this as I run these pumps in the garden Koi pond for the last 28 years. I know guarantee is invalid but they last well. Overall a good quiet and economical pump which will hopefully last many years. 24 Jan 2016
Rated 5 out of 5 by Pump Replacement Had a pump fail on a sunday, screwfix had this in stock at a good price. Easily fitted as exactly the same size as existing pumps, comes with seals (not mentioned on site) quick connect electrical connections are easy to use and pump runs very quietly. Needed to rotate the pump controls for my application and easily done. 5 Jan 2016
Rated 5 out of 5 by Recmmended for DIY'er Just replaced my willow pump that I thought was quiet when I fitted last time and when I switch this pump on I could not believe how quiet it was and it self bleeds the air. When I went back to check for leaks I thought it was off but it was actually running, the willow you could hear running in the room and the pump is in a cupboard.. Wiring was so easy. spring loaded push in connection and on a plug connection to the pump. So easy to install. Best pump I have ever fitted over the years. Only time will tell how long it will last. So far I am well impressed 20 Dec 2015

Hi George75,

We would advise that you consult with a heating engineer and there may be slight variations within the two products.
