Quick question: can a flowson pump be replaced with a grundfos 15-15? They look the same size but the manufacturers instructions make the flowson about 2-3mm difference. Will it be OK? I believe that most pumps, Terrier/Flowson/Wilo/Grundfos, etc are stadard sizes for direct replacement, but I want to be sure first...

Assuming you mean replace the whole pump ther providing you have normal tolerances in the pipework then you can change it.
Be aware that Flowson is the cheap name for Wilo.
Presumably you want to use the Flowson because its the cheapest pump in B&Q ???

The heading implies its the other way round! Thanks for pointing that out Alan.
The same answer applies though.
However, one might question the reason for replacing with a pump which is about twice the price when they both do the same job!

They both pump!
Grunfoss have a ceramic bearing which is very hard. It copes better with dirty water for a little longer. They do fail more often from burnt out windings though.
The Flowson ( Wilo ) have a plastic bearing. They are fine in clean water and work for 10-15 years no problem. They virtually never fail from electrical faults.
However the plastic bearing being softer wears faster in dirty water.
I would fit a Flowson at home but then I only have clean water!
