Re: Priming you water pressure pump

Certainly you should check for leaks, but have you checked the suction in your pump? Based on the age of your boat, you may have an older Jabsco, which will last a long time, but might be getting tired. If so, you might look into a service kit. I have a 23 yr old (original diaphragm) Jabso for my shower sump and it self-primes easily, but I am thinking it's time to rebuild as preventative maintenance.

Several years ago I changed out my original fresh water pump from the older style to the Sensor Max version, which doesn't need an accumulator. It is much quieter and has also been very reliable. The new pump is in the $300 range, whereas the service kit for the older one may run you $75. If your pump is really old, this may be your choice, as a replacement older style Jabsco will probably be in the $400 range.
