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.

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.

Highly recommend. Works great. Never had any issues in last 3 years. Better than other expensive pumps like Grundfus which stops working after 1 year.

Easy to install, works just like it's supposed to. Awesome boost in water pressure. Wish I had installed this pump several years ago!

This is my second purchase. My first one survived a number of years but began to leak around the seal. I had been happy with it so I purchased it again. This time the upgrade model from the Amazon warehouse. And at a discount supposedly because it was a damaged box. The new one arrived in about 3 days Took about an hour or less to install and sure enough I had my high pressure back again. BUT.... it would not shut off. I asked about an adjustment for the pressure controller but no answer. The pump is supposed to shut off when the pressure rises and the water stops flowing. But it ran constantly. I had to unplug it to get it to turn off. Not sure if the pump was bad or the pressure controller was not working. I purchased a pressure gauge (from Amazon of course.) So 4 days later I check the pressure. The house pressure without pump is 60 psi. With the pump running an the kitchen tap open it is about 90 psi. Shut off the kitchen tap and the pressure rises to 98 psi. But the pump keeps running. So now it is obvious that the pressure controller switch is faulty. I replaced the pressure controller that sits on top of the pump. That fixed it and now I am finally happy. AMAZON, you owe me $39 for the pressure controller I had to replace. As far as the discount for the damaged box...There was nothing wrong with the box other than someone had removed a mailing label.....I am now believing that this was a customer returned unit that was placed back into Amazon stock without testing it.
