    Odd as it sounds, try denture cleaning tablets.

    Hi Tom

    Sticking valves are frequently caused by buildup of calcium from hard water or rust deposits.

    We are happy to repair any units, no matter how old. However, you can usually fix this quite easily yourself and save a ton of money.

    Uninstall the unit and lay down in a sink or tray. Plug the inlet pipes. Pour a mild acid solution into the outlet pipe until full. Solutions can include Lime Away, CLR, citric acid solution or even stop bath solution. Let soak for a few hours, rinse with fresh water and reinstall.

    This has been very successful for almost all of my customers.

However today the valves have started sticking again.

    I'm going to investigate further but has anyone else experienced this? - noting that when soaked in the vinegar the valves where in the closed position and perhaps I need to manually manipulate them somehow to dislodge some crud. As I'm in England I'd like to get the unit working again without posting off to the USA for servicing.
