Simer4075SS-01 3/4 HP Pressure Booster Pump

Does what it advertises, Pretty quiet

Quiet, great replacement

I’m on a 10 home community well. My initial pressure was 25psi, which made showers pretty unenjoyable. This pump boosted my pressure up to 65 psi and showers are now amazing! I also installed a pressure regulator just in case I get a pressure spike while boosting, I set it to 65 psi. One thing to take note of is must be mounted on a horizontal surface. I initially mounted it vertically on a wall and the pump wouldn’t shut off. I then went to the troubleshooting section of the manual and it said it must be mounted horizontal. Would have been nice if the manual said that in the instructions which I throughly read. You normally go to the troubleshooting section only if you have an issue. Other than that I’m very happy. I will be super happy if I get a lot of years out of it, time will tell.

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.

No follow through with waranty. Pump had major leak. I contacted the company Feb 12 and gave the info and photos as they requested. They said it could take 6-8 weeks to get me a new replacement. Its now May 21 and no pump... and no answer to follow up email May 1st. People just do what you said you would do.!!!!! Or give me a complete refund.

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 thing is indeed the ace in the hole. We wanted to get a water filter and softener but our house is about 100 feet up from the street, incoming water pressure was less than 45PSI. With a softener and filter it would have been even worse. Put this in and now we’re at 75-80, showers are great!

This is the third pump of this model I have purchased in last 12 years. Used in a vacation rental property so it gets hard usage. They tend to wear out in about 4 years though. I have seen the price almost double also but I guess that is to be expected. I have tried other pumps in the past and they are complicated to plumb in and require pressure tanks. This pump you just plumb in top and front inlet/outlet, plug in and you're good to go. I guess I'll keep buying unless something better comes along or someone brings a better model to my attention. Beware of which seller you purchase from, first pump I got this year looked like it was dragged behind a truck. Thanks to AMAZON seller made good and pump from second seller arrived intact and properly packaged. Thank you AMAZON!
