UPS3 15-50/65 Water Pump, Metal, Above Ground, Black | Metal construction, 65 L/min flow rate, 5 m lift height, flood control, rainwater management, electric

Easy to fit and very quiet. A brand name you can trust.

This pump is a standard size so is a very easy replacement for an earlier model of Grundfos. It is very quiet in operation and is much more efficient than the old pump, restoring the effectiveness of the central heating system.

Well it seems to have sorted my plumbing out

This pump is a replacement for my central heating system, the old pump failed due to the water level dropping (a failed cistern ball valve) which resulted in the pump running dry. That destroyed its bearings! This new pump is a little taller than the old one and because it was positioned beneath boards in the loft meant some more headroom was required. Not a big issue - and not the fault of the pump. This pump runs so quiet I couldn't hear it! I had to put my hand on it to feel the faint vibration to be sure it was running. Installation was very simple - about the same as fitting a domestic plug. Hope it lasts as long as my old pump, I have no reason to suspect otherwise as it appears to be well made.

When the pump arrived and I took it out of the box I looked at sceptically because it’s so much lighter than the pump it’s replacing. Easily transferred into the isolated system fitted exactly where the 26-year-old pump came from. The initial start-up was a bit noisy due to a bit of air in the system but the pump self vented after that it was whispered quiet fantastic

This was cheaper than getting the older model that looked identical to my old pump. I asked the central heating engineer if the old ones were better because I'd found that they seemed to be more expensive when I was looking. He said the new ones (from the same manufacturer, Grundfos) are just as good and cheaper. He believed that people were probably nervous not to but the wrong thing so would either ask for the older model to match the identical broken old one in place, or maybe their heating engineer might be taking advantage to get rid of an old model they still had on their shelves - and possibly charge extra for it. Anyway, I saved money and that was reassuring to hear so I just hope it lasts as well as the old one did! It seems in his experience with his customers over recent years I've nothing to fear. A few weeks in place now, working well supplying a 5 bed house and no problems with the pressure - radiators are quick to warm up. Very happy. Update after 2 years: [Apr 2025 now] still working well. Had no issues at all.

good item good price POXY DELIVERY. Should consider changing courier. didn't leave where requested sat outside all-night any one could have nicked it Evri gone right down the tube

I am no plumber, in fact before the pump failed if you had asked me what a Grundfos was I would have guessed it might me something from a Harry Potter book but this was easy to install in place of the old pump that sounded like a squirrel with a mallet had got in to the pipework. Probably took under an hour to replace, new style connector for power is a lot better than the original. You do need check the direction of flow arrow on the old pump and make sure you fit the new one with the flow going in the same direction. If this means your control panel is upside down, as mine was, it can be rotated 180 degrees by unscrewing the four bolts that fix it to the pump body, do that before turning the water back on to avoid a bad day, just saying. I would add that the instructions for setting the speed are as clear as mud for the amateur heating fixer. So if you are confused like I was the lowest setting appears to be perfectly fine for my Heatrae Sadia unvented system. Pump has been installed for a few weeks now and the squirrel has moved out.

Muy bien, cumple la función perfectamente
