Additional notes: This pump is also the direct replacement for the discontinued GC150 with the blue wet end.

This pump will perform at its best with 2 inch plumbing. This pump does not always perform at its best when plumbed in to 1.5 inch plumbing combined with running through a water diverter valve.


This pump was originally supplied with a grey wet end which is exactly the same as this newer black version. If you are replacing your old pump that looks the same but has a black wet end with an o'ring fitted to the discharge outlet, you will need to alter the plumbing on the pressure side of the wet end. In some cases if there is enough play on the pipe you can simply use a thick gasket to overcome this small problem.
