Hi, we moved into a house with a 3 years old underfloor system. I notice a small leak coming from the pin (sitting in manifold under actuator). I think the leak stops once the actuator is removed and taken off the pin. I suppose I will need a new pin unit but as a similar leak seem to be happening already with more than 1 pin I’m thinking maybe this is not simply a faulty 3-years old pin but possibly the failure is due to some rust particles in the water affecting the pins o-rings? Changing leaky pins alone should be quite easy but not sure if I need get into an expensive system flush to get everything super clean...? How sensitive are those pins?
