A Better Water Pump! - Overview First, sorry, this is a long one, but skip over any parts that bore you. If you have a marine diaphragm water pump that has started to act up and either doesn't run or sounds sporadic when it's running, this may be a pretty easy and inexpensive fix to repair it, just by replacing the pressure switch. We have a Pentair SHURflo pump that starting acting up after a year and this repair has been tested out for about 6 months and is working great! If you want to prevent this problem from occurring again, there are also instruction on how to upgrade the pump so that the switch doesn't wear out again.
