Rated 4 out of 5 by from Good value pump. Just bought this Grundfos UPS 3 to replace my old Grundfos along with 2 new valves.Have not fitted yet but have connected the cable to the plug in termination block,good idea but as mentioned in a previous review the screws to secure the cable ends are difficult to tighten as they weird Philip's head and are made of very soft metal,easy to chew them up,why not just use straight forward flat heads screws.

Rated 1 out of 5 by from Wrong BSP Connections listed The listing in Screwfix shows this as 1 1/2 inch as a direct replacement for the an old Grundfoss. It’s not found the new connections to be 1 inch BSP. Took it back with no problems returning at Screwfix but an extra journey and time on the job. Will never know how good it would be so marked it right down. Screwfix please revise the connection size so others don’t get caught as I did. Many thanks Robert.

Rated 5 out of 5 by from Replacement for 20 year old pu The old grundfos had 3 fixed and 4 variable settings so this was a direct if newer technology replacement. Easy to fit and as we have TRV's on radiators the PP setting works really well and pump is silent when running. Not the cheapest pump but very good product and if it lasts as long as previous pump will be excellent value.

Rated 5 out of 5 by from Grundfos UPS3 CH Pump It never ceases to amaze me how far technology has progressed over the years, and clearly this central heating pump is no exception. I fitted this Grundfos UPS3 pump after my old UPS2 unit became unbearably noisy - basically it sounded like a jet engine preparing for take-off every time it started. Upon removal, I could tell that the bearings were shot, so a new pump was in order. Screwfix had the best price available, so it was a no-brainer to order one for delivery. I fitted the UPS3 without any difficulty, and also took the opportunity to fit a pair of 'Perfect Pump Valves', while I was at it. I also chose to rotate the control head through 180 degrees prior to fitting, so that it was facing the correct way up after installation. This new unit is whisper-quiet, to the point that I have to actually physically check that it is running - it really is that silent. A row of LEDs provide an 'at a glance' indication of the pump's status. It's self-bleeding, so no messing around with bleed screws. My only complaint is that the small Pozidrive screws on the 'quick fit' terninal / wiring block are rather soft, and will shred easily if you are not careful. Apart from this, the pump is a superb unit, and my radiators are now toasty-hot again! Best upgrade that I have made to my heating system so far. Spend the extra cash and purchase this over the cheaper brands - you will not regret it!

Suitable replacement for Myson CP63?

Would this fit and work as a direct replacement for my current 22 year old Myson cp63? It’s a bit temperamental now and when it does work it sounds like a jet engine so I think it’s time to give in and replace it.
Asked by: Flockhead

Can I add this pump to system and keep the original pump running at the same time

Asked by: Farshid

Does the small 3 pin second electrical connector require a cover against water ingress?

If so can I fill it with a silicon sealer?
Asked by: Toshmarple

can a central heating pump appear to be behaving normally yet have lost some of its force?

I have a grundfos pump about 6 years old and it runs quietly it vibrates gently and the pump and pipes both sides are hot, so presumably it is pushing water through. But some rads stay cold. .

Turn off power to pump , take out centre screw , ( catch water in a bowl at same time) Put a small screwdriver in the shaft of the pump. Hold screwdriver tight and switch pump back on , If you can hold the pump from spinning , then pump is underperforming and needs replacing . If you cant hold it back and it spins screwdriver out of your hand , then its fine. Put centre screw back in.
