Does your Grundfos Macerator have start stop problems?
You probably need a new rubber Grundfos membrane or known as diaphragms if the symptoms are delayed starting, delayed stopping after pumping out the water, running intermittently or turning on and off when it feels like it.
If your Grundfos Macerator has never been de-scaled your macerator is probably full of limescale if you live in a hard water area.
The limescale forms all over the rubber membrane and stops it being flexible enough for the microswitch inside the control box to be turned on and off when required to do so.
Other reasons for your Grundfos Macerator to have start stop problems is due to excessive toilet cleaner use, after a period of time the toilet cleaning chemicals attack the rubber Grundfos membrane and it shrinks, making it tough and inflexible, the Grundfos may switch on and take a long time to switch off or start intermittently as if it has a mind of it’s own.
We recommend changing the microswitch as well as the membrane as you will notice a vast improvement when your Grundfos is in operation.
