Circulation Pump Parts

Circ pump parts for the "heartbeat" of your spa.

The average life of a Hot Spring circulation pump in our area is eleven years. These circulation pumps get a workout, circulating 5000 gallons every twenty four hours. The human heart pumps one fifth of that at a 1000 gallons every twenty four hours.
We have taken spas in on trade that were over twenty years old with the original circ pump. However, we have seen poor water chemistry ruin circ pumps in less than three years. Most premature circ pump failures were the result of tablet dispensers (floaters).

Bad DispenserBeware...
Dispensers have been sold as low maintenance remedies to water care. They always over dispense shortening the life of all hot tubs.

The problem:
Floaters often end up in the filter area, where the circ pump gets its water, dispensing concentrated amounts of chlorine/ bromine around the clock. This high oxidizing concentration moves slowly through the circ pump and heating system eating away at those components.

The remedy:
The best alternative to tablets sanitizers is a granular chlorine (sodium dichlor) or a granular bromine (sometimes called Brominating Concentrate) This powder is added to the spa after each use.

Does your existing circulation pump look like one of the pictures below?
