Received order in good time, flushed system before installing new pump which took all of 20 minutes. Replaced 40 year old pump- yes I did say 40 year old pump that was still running. Added inhibitor and now have super hot rads when winter rears its ugly head and mega hot water. Had to turn boiler stat down and hope to save a few quid on bills this winter.
Had to contact seller regarding a technical query and he was first class. Time will tell how it well it lasts but if you
flush your system and add inhibitor once a year you too will get longevity. Sorry plumber man! 40 years is some record to beat though!

Bought this as a bit of a gamble to replace my old CP63 pump. The new pump fitted a treat, really like the plug in socket arrangement. Best of all it hardly makes a sound - I am running the pump on the proportional pressure mode and have been walking around the house touching the radiators as its is so quite I thought it wasn't working. Made me realise what a bag of washers my old pump must have been. Actually woke up this morning in my own good time and not to the noise of the central heating pump cutting in.

Using the Grundfos app to easily scan the product ID of my existing - broken - Alpha2 L, this was the recommended replacement.
Really easy to swap out, with exactly the same plumbing fittings and size as the existing pump. New electrical connector and had to rotate the control bot 180° but all done and dusted in under 20 minutes.
We have heating and hot water again!!

Really easy to install. Runs silently. Solved my problem of banging boiler. Seems like an excellent product.

Early days but the Grundfos pump is easy to install and runs well compared to the old pump it replaced. Water circulation has improved and the boiler runs more smoothly. The pump arrived well packaged and in good time. So far so good. .

Arrived very promptly and before the estimated delivery date. It slotted in where the old model was removed from. Its very quiet although it did have some noise after a few days which was worrying but may have been air in the system - sounded very different to the other pump when some air reached the pump. All quiet and working fine for a few weeks now

Replaced a 20 year old UPS model, would have been an easy job if a gate valve hadn't been seized and needed replacing too. Much quieter and smoother running than the original. Could have bought a cheaper one but quality costs...

The electric supply wires were difficult to screw down due to flimsy terminals. Otherwise works fine using it for domestic water circulation. No manual speed control unless it's automatic.

First one lasted 5 years...not a lot of choices on the market and would had to change all our plumbing so we went with this same pump again....maybe this one will last a little longer.

I just wanted to echo the short life of this pump that others mentioned. Pump failing after just three years. There are two local service centers here in Tacoma. Both said it's likely better to just buy new and replace this rather than have it serviced at $120/hr labor rate, minimum 2 hours plus parts. Per the sales rep there is a "seal kit" that runs about $65. Our pump is leaking, making a higher/louder noise than normal. The rep suggests a dried, worn and/or bad seal. There are two great video's on youtube showing the complete disassemble of the pump to the point where I think that I or anyone mechanically inclined could likely service their own pump. I was quoted $750 for a replacement by one service center. Obviously you can get one for much less.
I removed the old pump and installed the new one myself. I'm a seasoned DIY home owner and fairly capable of doing most things around the house. In this case, it's really just a basic plumbing connection job. There are two connections: inlet & outlet. It just depends on your existing water lines as to just what connections and/or extensions. Both connections require only hand tightening. Both connections are configured to have some slight angling ability, that is there is a little "play" in the connections so the pipe does not have to be in an exact straight line in or out. Once installed, there is a top plug you unscrew and then you fill the pump with water to prime it before starting. Good Luck.

I have had 5 of these pumps in the past 12 years. They are work great when they work but they do not last long. This is used as a pressure pump for an average sized house. These pumps seem to average 2-3 years, if they work out of the box.
This new pump arrived with a 115 volt sticker on the box. It was a 220-240 model. I discovered this when I went to plug it in, after installing it, and plumbing. Fortunately I have gotten very fast at installing because I have had to repair and install so many of these pumps.
Grundofos generally makes good pumps. This model is an exception to the rule. Most of the supply houses have discontinued these pumps due to on going problems. Go with any other type of pump,if possible. I have these pumps servicing 2 location and only re-purchased so I would not have to modify the plumbing. I guess its time to modify the plumbing.

Bought this pump to replace an identical one that lasted almost exactly 10 years. Like another customer said "I must of got one of the good ones". Worked on and with Grundfos pumps along with many other brands in the industrial field for years and they are a good pump but like any pump some will deteriorate faster if the conditions used in are destructive such as sediment saltwater chemicals etc. Easy to install and they auto operate perfectly as a booster pump with town water when you live on a hill. Mine did arrive with a chip in the suction fitting where it was banging on the box because the carrier stood it on end. I replaced it with the one off my old pump and am asking the seller to replace it as I plan on rebuilding my old pump. Great price with Prime shipping and got it a day early so it was one less day of a dripping shower because of reduced pressure.

Grundfos makes a unique product line with their MQ series. These pumps work well and perform tasks that you can't easily do with other pumps. The down side is that their quality is spotty and you can't easily buy repair parts. I have been unable to find another mfg with similar product line.
My personal experience with this pump application has been a mean lifetime of 3 years. That works out to $130 per year to own this pump, which I consider too high. That said, the unique features this pump provides means I will continue to replace it with the same model and grumble about the cost. Grundfos should offer a way to buy repair parts. Currently, I have a $500 paperweight for want of a simple pressure switch!
Pros:
Unique demand pump design
All components are built in
Quiet
Cons:
Expensive!
Short life time to failure

This pump is not meant to last more than five years. This one only lasted one year. When I contacted Grundfos for warrenty repair, they provided local repair shop's phone number. When I called the shop, they don't do warrenty repairs. I emailed Grundfos again, and they never replied. Last two units lasted around five years. This unit was a lemon, and Grundfos does not stand by with their warrenty promise. I do not recommend this product because manufacturer does not care about their customers.
