Bought one. Ran until it burned out. No operable thermal shutoff. It will run when NO pressure is against the pump, so you need constant pressure to have it shut off when the flow is stopped. So its' "garden" use is only for an end sprayer -- NOT sprinker system. It apparently will get too hot if running constantly over a long period of time and if spigot is turned off, (reducing pressure) pump will continue running a vacuum . Dont want to chance it also burning out, so best to have pump and spigot on timers.

I HAVE PONDS, so i pump water from the ponds up to a 250 gal. IBC tank next to a garden area. I sit the Wasserman on the ground and for the intake, i added a garden house about 8 or so feet and I start a siphoning process from the IBC tank. Then the outlet is set up to go to a regular Faucet. With just a Marine Hose and regular garden hose nozzle, it will shoot water 15 feet or better. No real need to do that, I just use that set up to water the garden and have done that for well over a year. SO the pump has some serious time on it and still working fine.

Im a RV Technician and I use this pump for water testing, fresh system flush, winterizations, works great have it running off a Milwaukee 12v battery with one of them adapters. This thing works great with water, antifreeze, this pump puts out plenty of flow and awesome pressure, shuts off when pressure is built, comes with a bunch of fittings and the strainer, can't beat the price and how much of a workhorse it is! Highly recommend for rvs and other uses such as off grid, or for liquid transfer.

Great pump. I bought a second one as a spare for down the road. Great value for the money and durable.

I bought this water pump about 8 months ago and it already stopped working. This is the third time I’ve purchased the same one, and the same problem happens every time before a year. Very disappointing quality. The seller never responds to messages and doesn’t honor the warranty, which makes the experience even worse. When the pump works, it does a good job but it just doesn’t last, and there’s no support from the seller at all.
