Pressure Booster Pumps 115V/60Hz 3-Speed Cast Iron Booster Pump 1 inch Outlet 46/67/93W Circulator Pump for Home

The pump most definitely increases our water pressure to a much more satisfying spray. We love our showers and love that we can run multiple fixtures with little difference in water flow. We experience a pressure boost of literal 8-12psi. The down side.... one of the threads are starting to seep water even with a bunch of tape on the threads and a godly turn. It drips at a rate of roughly a drop a minute now. My husband noticed that the threads were a touch different than the standard threads and thought he accommodated with 8-10 wraps of plumbers tape. The other downfall is that with the pump constantly running it is getting warmer and warmer to the point where if you touch it it will burn you after 15 seconds. We don't know if its normal, but its nerve wrecking wondering if were going to have a fire or a water leak.*update almost a year later*Pump doesn't create pressure anymore. It turn on and you clearly feel when its on vs off but my pressure gauge says not a single difference. I am filing a claim so we will see what happens.*update 2x*I called Amazon and they ordered a replacement for me. The pump functioned perfect again for a month until my wife smelled something burning while I was at work. She traced the smell to the pump that was on for only 45mins that was so hot that it melted the piping! These pumps are a HUGE safety issue! We have ours hooked up to a smart plug controlled by alexa and turn it on when were looking for the little extra pressure with our showers or running the sprinkler if we do. I am astonished that everyone isn't experiancing these issues like we have.

Muy buena la bombita tiene 3 velocidades, sube el agua a más de 5 metros a donde la tengo puesta para recircular el agua a un calentador solas que se encuentra en el techo de la casa funciona perfectamente

The pump casting itself has threaded of an unknown size. The nipple adapters are required for connection use as the pump body has proprietary size connection with washer. The nipple adapters fit the pump fine - but the nipples are a very thin extrusion and the "pipe threads" for connection are so shallow I didn't even try to use them. Rather I used braided tubing that fit snuggly over them and a hose clamps. Working great, quiet with good flow. So 1 ding for the useless pipe nipple threads.

It is more of a circulation pump, not a pressure booster
