  Mascontrol Unit Leaking

  Posted by Archived on January 17, 2015 at 8:31 am

  I have a Mascontrol Pump Controller unit mounted on the AO Smith water pump for our Marathon that has started leaking around the diaphram cover. There are a series of screws holding it on but I am afraid to pull it off until I see if anyone else has had a similar experience. Perhaps there is an aging gasket causing the problem or even the diaphram itself. RainHarvest Systems outside Atlanta sells the entire unit new but that would require some pipe fitting work to replace it which I am hoping to avoid.
