Grundfos Arvostelua 

This is our second sump pump from Grundfos in our kitchen and both had the same problem. They are simply not reliable.
Every now and then the pump decides not to work and needs to be shaked slightly, then it starts again. Why oh why it does that? We had the very same problem with the previous one, and that's why we bought a new one, yet it has exact same problem.
We clean our sump weekly from sediments etc to avoid that but it keeps happening. We are about to go on a holiday, and what are we supposed to do now? What a joke!

I am building my house, I had the well drilled and I installed the pump myself.
For two years the pump has been running flawless with a generator wired directly.
Last week I installed the controller CU301.
The tabs for the flow sensor were so hard to open, that one broke off.
I believe I still under warranty for this.
I don't want to buy a $700 controller because a broken tab.
I will not criticize the design, but a connectors with screws would be more reliable.
Grundfos first should answer the phone with a live person instead of directing me to a near distributor.
And as a worst scenario, offer an exchange unit ir a repair option.

We have purchased and installed two large submersible pumps [7,200 GPM] for storm water. Both pumps had seal leak failures at less than 500 hours of operation [stormwater application]. We contacted our local distributor February 9 and as of this moment have a report on what was found but no contact regarding repair time, cost, warranty nor likely causes. It is virtually impossible to contact someone within Grundfos outside of an area distributor [who actually has no knowledge or capability to review or service the pumps we purchased]. This is a critical application and outside of one gentleman who does answer a call we have no insight as to when the one pump will be repaired.

While I was initially frustrated trying to contact Grundfos, when I did make contact, it was because of a return call from Kelly Wessels. She sorted my problem, was courteous and respectful and explained everything very clearly. She is a gem, and I am so grateful for her kind assistance and understanding.

Grundfos Scala 2

Vor drei Jahren habe ich mir für mein Hauswasserwerk eine Scala 2 angeschafft. Kurz nach Ablauf der Gewährleistung hat sie begonnen zu tropfen. Installationsfehler AUSGESCHLOSSEN, definitiv ein Materialgebrechen! Nach 2 Monaten war die Fa. Grundfos mal soweit, auf meine unzähligen Anrufe zu reagieren. Auf Anfrage einer Kulanzlösung wurde mir eine Reparatur um knapp 400€ angeboten!
Ein Gerät um 600€, welches nicht mal 3 Jahre hält ist einfach eine bodenlose Frechheit!
NIE WIEDER Grundfos, Kauft woanders nur nicht bei denen!

meine Gartenpumpe von Grundfos ist nach einem jahr undicht geworden...mein Monteur holte die Pumpe dann ab. Die Pumpe wurde eingeschickt Dez. 23... nach 3 Monaten noch immer keine Info erhalt und mein Installateur muss jede Woche nachfragen, aber wird immer vertröstet.... Jetzt Ende März sollte ich die Pumpe dann bald mal haben, da mein Rasen bewässert werden muss. Nie wieder diese Firma...

The service I've received from Kelly in customer support and Grundfos has been nothing short of exemplary and it is great to deal with a company that gives such good customer support!

One star but it should be minus five! I’ve had to wait 6 days just to get an appointment for an engineer to visit a home booster unit and will have to wait a further 3 days until they arrive…… .Your response that you were contacted on the 18th only compounds the problem. You were contacted on March 13th. Your system for dealing with this matter is so long winded it took days before we got a date for an appointment. In the end we spent £360 and your engineer was only on site for around 30 minutes. That has to be the worst value for money going. Another minus 5!

Regenwaterpomp Scala2 blijft draaien als een gek maar natuurlijk net buiten garantie gevallen. Blijkt dat het toestel Scala2 een slechte reputatie heeft want de electronica flipt volledig ook bij andere klanten. Het enige wat de klantendienst kan zeggen is dat ik dikke pech heb. Triestige service, best ander merk kiezen.

Noticed a leak under the pump. Sent one mail to Grundfoss and the next day they had replaced the pump under warranty.

Very professional and their fitter Terry was a good guy to deal with.

like most people, i've read mixed reviews but can only talk about my own personal experiences. My scala2 pump started to playup a few weeks back(continuous running issue) - raised this directly with grundfos via their online portal and I provided everything they requested - I received an email response within 4 hours, phone call from local engineer within 3 days and pump replaced within 7 days..

Købte en Grundfos Unilift KP250 AV-1 drænpumpe med vertikal afbryder. Forventede rimelig kvalitet. Pumpens vertikalafbryder fejler så vandet i pumpebrønden stiger - og reklamationsretten på 2 år er udløbet. Havde håbet på kvalitet der kunne holde mange år og et produkt man kunne stole på…

Im Juli 1999, wurde bei mir eine Unterwasserpumpe "Grundfos 3 SQ 3-49" als Wasserversorgung Komplett Paket in meinem Bohrbrunnen versenkt. Seit dem habe ich die Pumpe nie wieder gesehen. Bis heute, Stand 25.02.2024, läuft die Anlage problemlos! Danke für so ein zuverlässiges Produkt.

I'd rate it -00 if possible. We installed a Scala 2 in our brand new home the first week of 7/18. It failed late and we called. They said it was a recall unit and replaced it. Installed 10/3/21. 2/8/24 leaking like a rusty canoe. My neighbors have this same pump... Most for 10+ years. Were all on the same well. I feel the replacement pump in 10/21 may have been on the recall list. Can't reach anyone though, I was on the 281-994-2700 number holding for 2 hours. Sad way to do business, Grundfos. Sad. Sad, sad...

Grundfos Scala 2 residential water booster pump and Grundfos Customer Service

I have owned 2 Grundfos Scala 2 residential water pumps in my home. All installation was performed per manufacturer’s guidelines. The operating parameters of the pumps were well within recommended ranges.

Both pumps developed leaks after approximately 12 months of service. My review of online information found this to be a common problem with this pump model. There is a two year manufacturer’s warranty on this pump from the original date of purchase.

No attempt was made to diagnose the problem in my first pump and it was replaced under warranty by the Grundfos distributor. When the second pump failed one year later, it was not covered by warranty since it had been slightly over two years from the original purchase of the first pump. My distributor recommended that I contact Grundfos customer service.

I found Grundfos customer service to be unresponsive to my questions and disinterested in my problem. They would not give me any technical support to help me resolve the problem. I was unable to find any local pump repair shops who were willing to service this pump. I offered to send the pump back to Grundfos and have it repaired at my expense. Grundfos stated that they did not offer this option for service to residential customers.

So I was forced to tear down the pump and try to repair it myself. I was unsuccessful despite multiple attempts using Grundfos replacement parts. The following repairs were attempted:
1. Seal and O-ring replacement with Grundfos seals and aftermarket non-OEM seals
2. O-ring replacement and attempted O-ring resizing around impeller shaft housing
3. Impeller shaft sleeving with stainless steel shaft replacement sleeves
4. Inspection of impeller shaft, bearings, and variable speed motor control unit. No damage and pump was operational with excessive leaking from bottom drain hole of pump.
5. Pressure tank replacement

Obviously I was extremely disappointed with the function of two Scala 2 pump units with each developing leaks after 12 months of operation. I was mostly disappointed with the lack of customer service support from Grundfos to a residential customer.

I would strongly advise against purchase of a Grundfos Scala 2 residential water pressure booster pump.

I would also strongly advise against purchasing any residential product from Grundfos Corporation because of their unresponsive and disinterested customer service representatives.

This the only time I have ever written a review so that’s testament as to the strength of my feelings.
I bought a Grundfos Macerator from a dealership,
unfortunately there was an issue and I wasn’t happy with the option they offered. In desperation I turned to the Grundfos main office.

On contacting Customer/Technical support, there was a completely different attitude. The team were both professional and knowledgeable, answering questions, returning calls promptly and offering workable solutions. I now have a fully functioning system.

I cannot speak highly enough of there competence and would not hesitate to both recommend and purchase further equipment from Grundfos.

Hi,
I did a major upgrade/retrofit to my house in Ireland and installed a new Hitachi Heat-pump to replace a Gas Boiler. During the upgrade the plumber advised that I use a Grundfos pressurised water pump to provide a good water flow to my sink taps and showers as Grundfos were considered a premium brand of pump. I went with it and in fairness the first few months it worked a dream. That is until one day a few months later I noticed a water leak underneath the pump when I opened my hotpress to grab a towel. I reported this to the plumber and in fairness to him, he replaced the pump as quickly as he possibly could. He did mention to me that the pump supplier, that he bought the pump from, told him that there was a known leak issue with this particular Grundfos pump and that all replacement models should have the issue fixed. I went with the replacement pump in good faith, assuming the replaced pump would have no leak issues. That is until a few days ago, when I noticed a wet patch on the ceiling downstairs in the kitchen/dining area and I called out a guys who installs showers to have a look. I did assume that it was a shower tray leaking, but the shower installer diagnosed the issue to the Grundfos water pump leaking. I couldn't believe that lightening has stroke twice with the same Grundfos model pump leaking, eventhough I'd been told that the design issue leak had been fixed. In both cases, the Grundfos pump was installed for approximately 7-8 months before the pump started leaking. This time however, the leak was more serious and my downstairs kitchen/dining ceiling is destroyed. I can't understand why a company with the reputation of Grundfos does not recall all installations of the model (Part number of the pump:- 98562865) that I have, as there is clearly a design issue with the pump. I have since read numerous bad reviews online about this water pump complaining about the exact same leak issue that I have encountered. This has caused me serious stress and hassle, and I will be looking for Grundfos to pay for the costs of the damage caused by the leak to my ceiling. I really feel sorry for the plumbers who install this model of Grundfos pump as they have to replace the pumps on their own time which is not right as it is at their own expense.
Not a happy Grundfos customer and I certainly will make sure that a Grundfos pump never enters my house again.

I'm not just saying this because Grundfos have agreed to replace my 4 year old pump but the company's customer service has been great, the response to emails has been same day or next day and they have listened and I believe responded fairly, even the chat function on their website worked well, big thanks to Kelly for taking my case personally so I didn't have to speak with a different person every time I sent or received information about my case. Great product and customer service 👏

Our pump was installed 11 years ago and only recently we started to have an issue. I contacted customer service Ireland last week and was advised that as it was out of warranty they could not send out a service technician and that I would need to get an independent plumber. However this gentleman from Grundfos spoke at length to me telling me exactly what to tell the plumber to do. Today the plumber came and I rang Grundfos again and put the plumber on to the technician and together they resolved the issue. The pump of 11 years is working perfectly. I was so impressed by the service from Grundfos considering the warranty is well passed. I would not hesitate to recommend them as a company.
