Rated 5 out of 5 by Pricey but good Bought this for use as a destrat pump in a DHW system. It's a good quality well designed pump thats also ok for potable water (non corrosive parts inside). Runs lovely and quiet so i'm pleased with it, but it was quite expensive for what it is. 25 May 2015
Rated 5 out of 5 by Great Value Secondary Return! Great value pump for use on a secondary return system. Pump was purchased to replace a faulty item and it fitted a treat. No hassle, no problems! 10 Apr 2012
