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 booster was installed in-line after my shallow well pump. The shallow well pump puts out about 40-50- PSI in the house. I've been having issues with the pressure on the 2nd floor for some time and thought I'd give this a shot. As you can see by the pics, the install was pretty straight forward. I installed a Shark Bite check valve just before the Booster Pump. You can see by the gauges that I got just about a 20 PSI boost in pressure. This pump is not as noisy as some have said in their reviews - this one is quieter than my shallow well pump. So far very pleased with the quality and performance of this little booster pump.Update: 3-17-21 This pump still works as designed. One note to potential buyers - you do not need the GHT adapters for residential use. GHT is for garden hose. The fittings on both ends are 1/2" NPT and mate to female 1/2" NPT water pipe thread. Additionally, some have said the pressure switch has I and II indicating I for constant ON and II for when a drop in pressure is detected. My pump came with the labeling of MOVE - STOP - AUTO. I'm very pleased with this pump. If things change, I'll send an update.Update: 4-21-22 contrary to what some have said, you can put two pumps on the same line to increase your water pressure by about 40 pounds per square inch. I finished this project and my water pressure now at the second floor is almost 80 PSI. Just check out the pics. These pumps add about 20 psi each. Quite impressive.

The pump works well when installed. The fittings are a pain in the bum to say the least though. It took a couple of adapters to get the hose thread to pipe thread for PVC but in the end I got them there. BUT, both ends of this thing have rubber washers to seal with. And flatly they suck. It's very hard to get this to not leak. I'm still checking it daily because the first couple times after it run a bit it started dripping. Not cool. The second thing is this pump is LOUD. I have a dehumidifier that runs under my house and I can barely hear it. I hear this pump kick on every time a faucet is turned on or the toilet flushes and it's located in the crawlspace under the house as far away as I could get it. It also says in the paperwork not to run it more than 30 minutes at a time because it might overheat. So I suppose watering my outside plants using water pressure boosted by this is out of the question. That's ludicrous to say the least. I'm using it for now. But if it goes bad, I'll definitely be replacing it with something better.Edit: Lowered to one star. It lasted six months and died. Don't waste your money.

We live in a house on a well and like most wells, our water pressure isn't great. We normally run around 40psi on a good day and if the laundry is running, you can forget about taking a shower. I bought this on a whim and installed it. I have to say I'm very impressed - the water pressure goes up about 10psi when it's in use. We can now shower AND run the laundry at the same time! I've run the pump for eight hours while bringing up the level of our pool and, while it did get very warm, it didn't overheat which impressed me. I've read that people can run these in series and I will consider doing that to lift the pressure another 10psi. Really pleased!

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 booster is a lifesaver! Installed in minutes, it boosted our shower pressure from trickle to turbo. The auto-flow switch works flawlessly, and it’s whisper-quiet. Handles kitchen faucets and garden hoses simultaneously without strain. No leaks after 2 months—highly recommend for old plumbing homes!
