Grundfos domestic pressure pump constantly running

    I have one of these pumps installed for approx 5 years. In the last 12 month's or so it will be running almost constantly for no apparent reason when all the taps are turned off and I've checked for leaks etc. The only way to reset it is either switch it off or turn on a tap at full blast and leave for 20 seconds or so and even this doesn't work all the time. It's starting to bug the **** out of me now. Is there a way of regulating the pump or resetting it or why would this be happening? It doesn't happen all the time but definitely happens a few times per day on average.

    I believe there is a flow switch built into most of the Grundfos pumps, it might need replacement.

    They have really good info and documentation online for most of their pumps if you type the make and model or product code into their website. A lot of the time they have troubleshooting info in the manual/install guide.

    Thanks for that, I'll have a look.
