Simer 4075SS-01 3/4 HP Pressure Booster Pump

The Simer 4075SS-01 boost pump caught my attention because it was compact and the its performance fit my requirements. I chose to install the pump after my water filter system as to protect the pump small debris, and put check valves before and after the pump to keep the flow going in one direction. Doing this also keeps from pump full with water during maintenance work with filter changes, and water softener servicing. What I observed with the water pressure regulated to 40 psi, the pump will maintain a steady output of 80 psi. Noise level is quiet, like a soft humming sound (heard from upstairs), and the pump runs smooth, so it never vibrates at all to warrant using flex lines as other installs have recommended. I think with the check valves I placed accordingly there is a 7-10 second delay before the pump starts up. I have the pump mounted on two L-brackets attached to the wall that keeps the pump 12-inches off the floor, its small size freed up space in my small utility closes. The monitor panel is easy to read, there are no numbered fault codes to decipher, it simply tells you power on, pump on, failure, and reset. The power cord with 3-prong plug makes the Simer boost pump plug & play. Overall I am happy with my purchase. Highly recommended.

Reasonably price and does the job so you can take a shower and get the shampoo out of your hair. It is actually pretty quiet when it runs

Just hooked up my pressure booster pump, this is such a huge difference. I used it to test the showers and faucets. The pressure is unbelievable. This is well worth it. Once the pressure fills up, the pumps cuts off at 55psi. I was able to have a long hot shower to test the system and it never dropped pressure. I would definitely recommend this product. ****UPDATE*** I ordered this in March 2022. It’s not October 2022 my booster pump stopped sending pressure into the house. I went to check and found out that the pressure gauge was at 5 and noticed all the water leaking out. I turned off the water and inspected the pump thinking it was a seal. Found out the plug (drain plug probably) underneath the housing was no longer screwed in, it was just hanging; I took it out and tried to screw it back in. The threads had somehow worn themselves out and the plug was now just a push in. So I switched the top plug with the bottom and it screwed in. Now I have to call the company to replace the top plug and probably get a few to keep on hand. The threads on the plugs are very minimal making to only about three turns by wrench and it stops. Pressure pump is now working great again. So beware of the failing plugs. Not sure if my water was that bad that it corroded the plug or if I had a faulty plug that was just wearing away.

So far works extremely well. Low noise level. Truly excellent pressure. I had to install reducer to get pressure from 100 psi to 60 psi in our mountain home. We have private well and after installing all filters the water pressure was week on second floor. Got cheaper pump and the noise was unbelievable : it sounded like someone would drill into the wall. You need pressure reducer on outflow for sure possibly intake. I purchased adaptor for pex tubing x2, pressure gauge , and pressure reducer. Plugs into 110V recepticle. Easy install for an average handyman. Very satisfied. The plate to fix it to support is rather flimsy and came bend on arrival. Something should be fixed considered that this is not a cheap unit.

It boosted my pressure from 35 to 75psi. Easy install, be sure to put plenty of teflon on the 1” fittings. We put the pump under the house on one end. You can hear the hum of it kicking on from the opposite end of our home. It is noisy. I can’t speak on the build quality since I have only had it in for a week.

This unit works great,but after about 5 months. It started spreading water everywhere. I called the manufacturer and was told to contact the seller. I ordered a new gasket kit because I didn't feel like waiting for an answer from everyone, then as I took it off of the basses I had made, I realized the lower drain plug had rusted completely off of the machine. I finally got a response from the seller who has told me that they were submitting a warranty claim, but that was 3 weeks ago. I've tried to find any top of plug that would fit, since I measured it as a14m 1.50, but that doesn't work. Can't find a part anywhere. The seller has told e that they have been working with the manufacturer about the warranty claim for months. The only contact I have with them is if I write first. If you have to have one, read the reviews and make sure it’s SS. Buy from a different supplier!

So far pump works great. My pressure from my well is 45-65, with this pump it’s 55-95. You can hear it run but it’s not loud or distracting. It’s made in Italy which I prefer. Hopefully I get years of use out of it.

I'll say this pump definitely does what it's designed to do - this will add a good 35-40 PSI to your water pressure. The listing says it provides "up to" 40 PSI of addition pressure, which made me think this might be a variable speed pump. It's not variable speed. So if you're already getting 50 PSI and you're looking for just a little more, this will bump it up to 90 PSI, which is going to be too much pressure. That's not the end of the world, since you can just install a pressure regulator to limit the pressure to what you want or need. The deal-breaker for me on this is the noise. We had it installed in our garage which is attached to our house - the garage shares a wall with the kitchen. When the thing kicks on, it sounds like an air compressor or something, and we can even feel a bit of vibration. Bottom line, I would say this is a great option if you are at 40 PSI or less and need 35-40 pounds of additional pressure; and only if you have a remote place in which to install it that is nowhere near the main living area of your home because it's LOUD.
