I purchased this Grunfos S.T.N-3.0 B on the 29-10-2025 after a prompt delivery. It was fitted yesterday replacing an old pump that had been fitted in 2007, very happy with the results.

The pump arrived promptly and works well
This was a like for like replacement for an existing pump that sprang a leak from the pressure dome actuators The pump works well and is relatively quiet. A longer than 2 year warranty would be good
