Well, my fresh water pump has developed a hiccup. It pumps just fine in use but after I close the faucet, in about 10 to 15 seconds, the pump will come on for a second then shut off for another 10 to 15 seconds. Just a little "burp," but it is annoying. I know it is losing pressure past the check valve, but I don't know how hard it would be to repair. I can get a whole new replacement pump for about $90.00. So, is it worth it to try to repair a 5 year old pump, or should I just bite the $90.00 bullet. Thanks!!
