suitable pump replacement

JonathanJonathan Registered Users Posts: 1
Hello. I have a cabin that is built on a large rain water tank that fills from collecting water from the roof. To have a shower water is taken out of the tank to a pump located next to the tank about 1 or 2 feet above the usual water level. It is then pumped to a gas water heater located about 6 feet above it and then to the shower head that is a couple of feet higher. It has been using a shurflo extreme smart sensor 5.7 for the last 8 years or so. Sadly it seems to have now died so I am looking for a replacement. The recent reviews of the shurflo looks like their quality control isn't what it used to be so I am looking for something different. The old pump self primed would produce 60psi with a max flow rate of 5.7 gpm. It replaced a 3.8gpm pump which wasn't able to keep the gas heater lit so it needs to be at about the 5+gpm. The cabin has a 24v battery bank and has no options for gravity feeding so the work needs to be done by the pump.

I haven't really been able to find a suitable replacement and have been thinking of using a mains pump. It doesn't get a lot of use and the battery bank has some spare capacity so the power loss isn't too much of a factor if it gives me what I require.

Does anyone have any suggestions?

    Check these out:

    They reportedly are more reliable than Shurflo and Flojet pumps and made in the USA. I just ordered one to replace a failing 2 year old Flojet when I could not get a response from their tech support.

    I am a big believer in Aquatec pumps ( own 4 at Present ) and have had great service with them. While the smart pumps are nice one should be selective in their placement. They have a higher amp draw than the same pump with a On & Off pressure switch. The On & Off pressure switch versions the switch is adjustable with a allen key from 20 psi to 80 psi. If you have something you fill that has a constant volume and flow, I think your better off with them, I have a small pressure bladder tank I fill on a water jet toilet and the smart pump had problems filling it because of the back pressure. The smart pump is fixed at 65 psi.

    If the Shurflo smart sensor got eight years of service before it failed you did not do that bad. I would just rebuild it if I had the time.
