Booster Pump Works Great!
By Roger M
South Carolina
Purchased 01/28/2025 |
Review Posted 01/31/2025
Purchased the booster pump to increase city water pressure which was currently at 40psi at the meter. After installing, pressure increased to 85psi. Highly recommend this pump for anyone who has low water pressure going into the home.

Works Great So Far
By Bruce L
Washington
Purchased 08/12/2024 |
Review Posted 09/04/2024
Only had it running for two weeks but it seems great so far. No leaks. It boosts our city water pressure from 40psi to 80psi. It is quiet. I had a Grundfos Scala II and it started leaking after a year and could not be fixed. I hope this one lasts a whole lot longer than that! The increase in pressure make the lawn sprinklers work like they are supposed to and it's nice when taking a shower.

Pump Used On Sand Point Well Sysyem
By Dave D
Wisconsin
Purchased 05/03/2024 |
Review Posted 05/24/2024
Pump works great, and the folks at waterpumps direct were very helpful at getting my configuration set up. The pump is a little noisy, but well worth the pressure increase. I did put a pressure regulator on the discharge side.

1 Month After
By David D
Virginia
Purchased 01/30/2024 |
Review Posted 02/22/2024
Easy install with my existing well system. Max working pressure is 80psi. Since this pump boosts to 40 PSI over input pressure input pressure had to be reduced by using a 30/50 PSI pressure switch. 1 month no issues and outstanding water pressure in 3 story farm house. Just waiting to see if there is any noticeable increase on the power bill.

Expert Response
Based on what you described, you may want to check your plumbing system for a leak. Due to the functionality of the controller (pressure switch), a leak will cause issues for this pump/controller. For warranty support, Simer can be reached directly @ (800) 468-7867

Water Pressure Booster
By Ron
Maryland
Review Posted 06/17/2023
I've had my Simer 4075SS for a few weeks now. It was a replacement for my Simer that lasted about 12 years...so no complaints at all. The hook up was pretty simple since the basic pipes were already in place. The results have been very good. The 4075SS can support our household needs along with our 11 zone sprinkler system. I would absolutely recommend this unit along with going through Water Pumps Direct. The process was simple and without issue.

How To Replace Your Leaking Grundfos
By Captain Pete
North Carolina
Review Posted 12/20/2022
While the fittings are the same, the outlet of the pump is facing upward. If you used flexible connections it will not be a problem. Both solutions for increased water pressure is expensive, to avoid twice the cost choose the Simmer over Grunfdos.
