If you have the original mechanical pump, call Then & Now for a USA-made repair kit and rebuild it.

If you do not the original mechanical pump, call THen & Now for a USA-rebuilt original.

There should be no reason to replace an original mechanical pump 3 times in 4 years. Generally, I get about 30 years out of one.

As to electric pumps, to each their own opinion, but here is some added information to chew on:
