    Default broken manabloc valve

    I have a manabloc system and I broke the diamond shaped head for the shut off valve. I have an open port directly above the broken one and was wondering what it might cost to have it switched or to repair the broken valve? Is it something that someone with no plumbing experience could do themselves with good directions?

    Thanks

    Can you get that broken valve to shut off?
    Try it with the main shut off and the pressure bled down.

    If that works switch it over to one of the unused ones...

    No I can't shut it off because the tip that the key goes on broke off. I really know nothing about plumbing. Do you mean shut off the main to the
    house or is there a main shut off to the manabloc? How do you bleed down the pressure?

    Can I just pop off one of the red caps with an unbroken tip and switch it with the broken one avoiding having to mess with any of the water lines?

    Thanks for your help.

    Default Manabloc has a ten year warranty

    I too had broken some manabloc valve stems. I called Vanguard at 800-775-5039. They referred me to my local district manager who scheduled a plumber to come out and replace all the valves not just the broken ones at no cost. Apparently there was a design flaw as my contact said it is a very common problem. Hopefully you are within the 10 warranty period as they confirm with the city when your house was built.

    I hope this helps

    Good Luck

    Default repair

    If the valve cannot be repaired, unfasten the tubing from it, remove the wood between that hose and the hole above it. Raise the tubing and connect it to the upper valve, then obtain a piece of PEX tubing, and a Sharkbite cap. Connect the piece of tubing to the broken valve and push the cap onto the end of it.
