You need to 1st check whether you have any water in the tank and check the bilge for excess water a good sign of a leak. If you are drawing water from the storage tank you should be getting it out of the fawcett. If you are not you are drawing air into the system, this is probally occuring before the pump. You need to check each and every connection in your system for tightness and leaks. That means every single hose clamp must be physically checked, Starting from the water tank to the pump to the accumlator tank through each sink fawcett. There is no big deal in doing this however you may have to crawl and look in some tight places. A couple small screw drivers, long and short, a hose clamp tightener and a small mirror to observe around corners is helpful. Consider this a good time to become familiar with this system. If you had the pump installed and don''t feel comfortable checking this out I would take it back to where the pump was installed and have them trouble shoot the complete system for you. Really this is a simple job and something we all should be able to do on our own boats. Good Luck
