Pump install – Pump is really easy to install the multi coupling feature is perfect for any pit being able to adapt is a key function with the pump. The ability to pump and pressure from pumping is great from a smaller scaled pump Show details

Excellent submersible pump for home use – The original Divertron pump that came with my house gave up after 12 years. Researched replacement pumps and found the Grundfos SBA were recommended… Read more

for my type of residence. The Grundfos SBA was very easy to install myself and provides good power for the household water. The best improvement noted is that the water pressure remains more constant than previous and it is not turning on and then off all the time like previous pump. Highly recommend.

Amazing water pressure to house – We are not on reticulated water so rely on a water pump to our house. We replaced our old water pump of 16 years due to starting to fail. Our water… Read more

pressure has always been a bit low and we suspected issues with our dishwasher not working properly was due to the poor water pressure. It was super easy to install (thanks to my hubby) and OMG the difference in water pressure is incredible. Our dishwasher now works properly as well. Totally recommmend this product.

Not a straight forward pump solution – Bought a Grundfos CM-PS CMB3-37 and a 200ltr pressure tank, about 7 months back and found the following; 1. the first 200 ltr tank that arrived was… Read more

broken on the plastic base. It was so weak, it could not be stood on its base, when slid out of the box. I rang my mate, who is a 4 year year Mech Eng. Who berated me for buying chinese gear, when he saw it. When the replacement one arrived, we very carefully slid it out of the box and did not let it touch the ground, then picked it up and slowly put it down, in the vertical position. Its a 2 man job, don't try this on your own. 2. The flexible hose that connects the base of the tank to the pump head is too short. You have no options on movement, when you get it connected. Needs to be a bare minimum of 200mm longer. If you use the inline filter, the pump has to sit 100mm or so higher, off the ground, so the hose is too short. 3. The Grundfos filter unit leaked like a sieve. I tried turning the o-ring upside down, stretching it a little, but no joy. I ended up putting 10 winds of teflon tape around it, and that fixed it. 4. The air bleed valve on the inlet side of the pump had a slow dripping leak from day one. Needed teflon tape to seal properly. It was hard to trace where it was coming from. I thought it might have been one of the pipe joints. 5. The pressure dial arrived with a crack running from top to bottom on the dial, but the box had no signs of impact or scratches. [See picture] I wondered if it had been a sale return to the Grundfos warehouse in NSW? Who knows. 6. I tried making the adjustments, as per the instructions, for the cut in and cut out pressures, but there was no perceptable change in output pressure. because the pressure is average, the washing machine needs to have water added by hand with a bucket, otherwise it dosen't get enough water, in time, when it starts its cycle.

So in Summary, i think you need to spend more. This one struggles, on a 3 bedroom house. In hindsight, I would have sized it larger, if i would have known the outcome from a practical level. I would have liked to be describing a better experience, but for me that was not the case.

Grundfos Quality Issues – I had a Grundfos SP2A installed in 2003 that failed in 2007. The Grundfos agent advised us to try a larger pump, so we had them install an SP3A-33 in… Read more

our 100m bore. The pump was designed to pump up to a tank on a hill, producing a total head of 160 m. While the water quality is fairly soft and suitable for stock and garden use, the pump has again failed.

Upon inspection, it was found that a weld had failed on one of the 3 straps, designed to hold the 33 stages together. A weld that attaches the drive hub to one of the 33 impellers also failed. The combined failures of these welds, has contributed to a failure of the drive shaft, between the motor and the pump. The pump has to be replaced.

Grundfos failed to satisfactorily respond to the problem, simply offering a heap of unrelated excuses. It appears that Grundfos have quality and durability issues with their products. Several farmer's in our area have reported experiencing similar problems with Grundfos bore pumps.

I would say that while they charge a premium price for a product, which they claim is very durable, this is not the case. A far cheaper pump costing a third of the price, that only lasts half the time, might be a better option.
