  1. In a previous post I was dealing with a Cat pump with reduced pressure. As often happens the simple solution was to just swap it out with a stock electric pump. Then the new electric pump would run great for 10-15 min and shut off. After 3-5 min it would come back on. The more nozzles were open the longer it would run. Since this seemed like a heating problem - I checked the pressure relief valve to see if it was returning water to the tank. Which it was. More investigation revealed that the Cat pump uses a 50 PSI relief valve, whereas the electric pump uses a 25 PSI valve. So I was getting too much back pressure causing the pump to overheat. Now with the proper 25 PSI relief valve - everything works great. Hope this post saves someone some time.

    Cat Water Pump - reduced pressure?

    2016 Tymco 435 w/ Cat Water Pump - Pump just went to about 1/2 pressure. I say pump, but the pressure at the nozzles is 1/2 of normal. Did the normal filter check and confirmed good gravity flow into the pump. This model has the addition of a pump on/off switch by the valve bank for use with the auxiliary water wand. Is this a pump issue or is there a check valve or other choke point to check first?

    Yes, that video would be amazing. Have done this solo several times and 45 min would be a good day. Better yet, I have one due. Come on up to the OC and I will film you doing it. :)
