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.

The water pump runs smoothly with minimal noise. Its power is more than sufficient, and everything is just right to meet my needs.

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.

I bought 2 pumps that I had to return before I found this one. The SEAFLO 55 Series ECO-WORTHY 33. These pumps had some sort’s of problems like plastic tubing adapters that leaked or motor working sporadically. So when I saw this pump with brass adapters. I thought, wow that looks like a good quality booster pump. They 3 time is the charm. Well let me tell you this pump preforms very well and it quite when compared to the other 2. It’s the only booster pump that mention the height this pump would push upward. Aka head pressure from the previous 2. Which I believe can handle up to 50’. I was pushing 20’ to the upstairs shower. Finally we have good pressure when taking a shower. I added a strainer before the pump which will help with the pump’s longevity.

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.

This booster pump is highly practical and easy to install. It delivers excellent pressure, performs superbly, and operates with minimal noise—living up completely to its claims.

I got the pump and I installed it last night. It was a little harder than I had anticipated as the hoses that I had available were not the proper fit so be sure that they are 1/2" female side to whatever connection you have in the boiler, and 1/2"female as well for the water supply. No fault from the supplier there. The package comes with a very cheap Teflon tape. It is appreciated but I definitely recommend for you to get one from Home Depot or a similar hardware store. I tried to use it and it started to leak water in two different places. I had to redo it again using a better Teflon tape with much better results. The instructions booklet is essentially useless. The instructions are very unclear so you have to figure everything out by yourself. It would not hurt for the manufacturer to invest a few bucks on making a more detailed instructions booklet considering that this product is not cheap. The water flow improved, no doubt about it, to the point where the pass-through boiler is no longer failing to start on demand. Do not expect to see a huge improvement, though. It will change from a trickle to a decent water flow but it will not do miracles. The final point is the noise. I mounted the pump to the wall in a vertical position. I secured it to the wall by tightening screws on the side plates of the pump. I selected the position with the two bars ( || ) and not the ( I ). The booklet does not mention it but this position ( || ) is for the valve to control the pump while the ( | ) position is for the continuous function of the device. It is enclosed in a service room and it can be heard all the way to the kitchen so it is a little noisier than I had expected. My only complaint really is the manual. If you are not savvy about plumbing it is not a true DIY product. Edit: Not so much related to the quality of the pump but I ran into an issue last night The hot water hose started leaking a significant amount of water. It was already in a very bad shape and when I replaced it with the one that I had previously removed from the cold water side, it broke as well. To make matters worse, when I installed the new hoses this morning, the valve for shutting off the water flow started leaking as well. Bottom line: The increase of water pressure will most likely affect the old system so make sure that you need to replace them as well when adding the pump. It was not funny to be soaking wet in the middle of the night trying to at least do damage control to the situation. You have been warned :)

It significantly increased the water pressure in my home. It automatically starts and stops via a flow switch, runs smoothly, and its high power and efficiency are perfectly sufficient for simultaneous use in the kitchen and bathroom. Installation is simple, and it operates with very low noise. It's an excellent product that meets my needs.

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!
