My pump(Grundfos STN-4.0 B) has started to cycle on/off. I had a plumber come to investigate and he said it isn't a leak anywhere so suggested I call Grundfos to get the valves changed as most likely the issue. I rang the Dublin number to check it in but have been told I have to go to the premises in Ballymount to get a quote but I need to bring the pump with me so they can see what the problem is. I asked for an email address or phone number but was told they don't have either. I asked if they had a phone in the building and was told NO. I want a quote to replace the 2 valves and asked for this before I remove the pump but was again told that I would have to bring the pump to the premises. Beggars belief how these guys are in business. Wish I had looked at Trust Pilot reviews before I bought this pump. Haven't seem a worse reputation.
