Fit and forget

I had gone through so many different brand pumps until I bought the Grundfos.
I now have 3 on the farm. One 10yo, one 6yo and just got a new one for the shed.
Fit it once and forget. Never had to do anything else.

Purchased in for $1,391.44.

Hoping this lasts a few years

So far, good. Other pump (a different brand) lasted only four months beyond warranty period. Hoping this one lasts considerably longer. Show details

Pump lasted 6 months, Grundfos were no help

Paid $750 for a Grundfos cmb 3, thinking I was buying a quality pump. Within 6 months it was dead, as water had got into the electrics. Despite a 2 year warranty Grundfos would not repair or replace the pump. Apparently, their water pumps are not supposed to get wet! How about putting proper seals on your products? Meanwhile, we had no water to our house. We went to our local pump specialist, bought another brand instead and got some actual customer service.
Avoid! Show details

Reliable Pumps

This is my second Grundfos pump which I purchased as a spare. The first pump is still going strong but wanted a backup over Christmas. Very happy with the reliability of these pumps!! Show details

So Quiet!

Pump was in-stock & delivered the same day as the old one broke. Straight forward installation and its so quiet & smooth running. Great "lift" performance and pressure throughout the house. Could not have hoped for more. Show details

Reliable Pump

Our Grundfos is reliable and quiet. We often turn the power off to the pump, and it always starts again without issue when power is turned back on. The pump is quiet. The water pressure is great. We are using the pump for tank water to our 3 bedroom house. Show details

This is the perfect pump for our hot and cold water supply

We run off Gravity fed hot & cold water. This makes showering slow and unenjoyable. The pump has allowed out system to deliver hot and cold water at a better rate for enjoyable showers Show details

Solid and quiet !

My old water pump gave up and I was recommended the Grundfos CM Booster to replace it. It's a solid, reliable and quiet replacement and I'm very pleased with it. Show details

This pump is ideal for our domestic needs, both inside and for garden. Easy to install and requires minimal maintenance. I have been running two of these for over 20 years and only replaced once.

Hello, I have a new Grundfos CMB 5-46 installed on a new house. Every 10 minutes or so, the pump comes on without any taps being turned on. I cannot find any leaks. Could it be the pump settings need to be adjusted?

Hello, we've recently run out of water in our rain water tanks the pump was attached to and ever since they have refilled the pump the water pressure has dropped significantly. Any help would be greatly appreciated.

Would the fact that we get a quick burst of good pressure which quickly turns into low pressure when we use any taps the pump is connected to change anything?
