Easy to fit replacement
Friday, 16 September 2016  |  Peter

This pump was a direct replacement for our hot tub. No problems fitting - it had the right form factor. Just one small point, the input pipe leaked when first connected. Had to make a washer as the seal provided was not quite big enough to cover the pipe. Otherwise all good and working well. Thanks!

ok but problem fitting the top hose due to shorter pipe coming out which we have resolved by fitting several seals....the gap is approx 15ml difference.
