120W Water Pressure Booster Pump 115VAC,396 GPH,21.7 PSI Household Automatic Home Booster Pump with Water Flow Switch for Home Kitchen Bathroom Irrigation(H15GR-15)

This water booster pump was very easy to install. We used it at our condo. It has helped with adding more pressure to our water especially during showers. I like that it has an automatic button and will only run when you turn on the tap. I found the price to be reasonable. It is a bit loud when you turn it on however you get used to it.

This water pressure booster pump works perfectly and delivers strong, consistent water pressure throughout my home. Installation was easy, and the automatic flow switch turns on and off smoothly when water is in use. It’s quiet, efficient, and ideal for the kitchen, bathroom, and irrigation needs. Great quality for the price—highly recommended!

I ordered the KolerFlo H15GR-15 and received a mangled box of incorrectly packed pump and missing parts. See attached photo. I immediately reordered a replacement pump. I received it yesterday in good condition and properly & neatly packed. I unpacked it and got it installed around 8:30pm as a backup pump for our gravity fed water system. Our main pumping system is currently broken and we’re waiting on parts, so I purchased the KolerFlo as a backup system. After installing the KolerFlo, I turned it on to the “Move” position and proceeded to purge the lines of air bubbles. Afterwards, I came back and switched the KolerFlo to “Auto”. The pump would switch on then off, then on, then off, for about 5 minutes. Around an hour later, my wife went to take a shower and told me there was no water pressure. I went and checked the pump and it was still set to Auto, but would not turn on the pump. I switched it to Move again and it started pumping. My wife took her shower. Afterwards I set the pump to Auto and it started the surging, on, then, off, then on for about 10 times. I checked a faucet and there was no water coming out. Obviously, the pressure switch is garbage. This is almost exactly as described by another reviewer. Do NOT buy this junk! I’ll be sending it back.

Received pump quickly from Manufacturer and installation was not difficult. The time consuming process is re-route of piping that I had to sweat on. Running Pex would have been simpler however I do not have tools for this so decided to sweat it with copper. It is important to run a bypass in case you want to pull the pump for whatever reason. Install a shut off valve prior to pump ( which you need to anyway) and then run a line that bypasses pump with another shut off. Bypass line will have valve in closed position unless need to remove pump later. No leaks using standard 3/4 copper female fittings and pump unions with provided rubber gasket. I am using the switch setting to I which will turn on when hot system calls for it. Setting II is always continuous on which I am not sure why there is that setting as leaving it on will likely cause the pump to fail and burn out over extended periods. This pump directly feeds my hot water tank cold line into tank. Check valve installed prior to pump inlet. I have added just under 10 psi to my hot water system. I used 3 elbows from the pump outlet to the cold in on the tank which is probably why I am not getting full advertised PSI. If i had to run it again, I would have installed it in the horizontal position directly before the tank cold in on a vertical copper run. This would have eliminated elbows. The unit is noisier then expected. I can hear the pump turn on on the second floor however bathroom on second floor is just 14 feet directly above where pump is installed. If you install it further down the line somewhere, it would be less audible however it would lack the power to provide any additional PSI that far down the chain for a whole house system. I also did not want the pump turning on simply when using cold water for any branch off cold lines I would have if pump installed down the chain. Overall, increased pressure in shower which is noticeable. Eventually , Ill buy a 700 dollar Davey pump and never think about it again. I do question the longevity of this unit, not including rubber seals which will eventually breakdown and leak. There is also a rubber seal around the pressure sensor that has the potential for failing down the road. I would not install this pump if you do not have a floor drain in your mechanical area. I don't believe the durability of this pump will last more then a couple years and adding it into your system is only providing a week link. If you have a floor drain in your mechanical area, you can feel better knowing your basement wont flood. There is a "model 20" unit which I could not seem to find. I would have rather put that model in since I was already doing the leg work. I do not like how the inlet and outlet step's down 3/4 to 1/2 inch. The "20" model is 1 inch and likely steps down to 3/4. Thank You,

This 120W Water Pressure Booster Pump has made a huge difference in my home! I installed it to improve weak water pressure in my bathroom and it works even better than I expected. Right out of the box, the build quality feels solid and well made no flimsy plastic parts and the motor feels durable.

My plumber plugged it in and the motor seized immediately and smoke came out of the pump. It does NOT work and I cannot get the seller to return my money. DO NOT BUY THIS UNLESS YOU WANT TO GET SCAMMED.

I installed this pump to increase hot water pressure to the upstairs shower. the pump was installed with an access door in between the closet and bathroom wall. it works very well! we have excellent hot water pressure all of the time. the pump turns on/off automatically and after 3 months, it's still working great. the only reason I gave it four stars is because it's really noisy. I don't care what the reported db levels are, it's noisy. that being said, we're used to the noise and it really doesn't bother us. I'll take great hot water pressure over a quiet cold shower any day!
