    Macerating Toilet Venting
    Hello,
    I am having a saniflo sanibest system put in a basement bathroom by a local plumber, and it includes a sink and toilet. They seem to be intent upon using a studor vent for it. I don't believe they can because the basement is below all of our other water appliances (2 bath/showers, kitchen and laundry), and they are not hooking into our main vent system. Wouldn't they need to run the vent for the saniflo toilet above the level of the highest water appliance (which is above the bathroom by 10 feet)?
    Thanks for your help.

    Hey Smartgal!

    Hey, you're right to be suspicious!

    Here is a link that brings you directly to the sanibest installation instructions:

    http://www.saniflo.com/downloads/ins...EN_April07.pdf

    Check out page # 3 of 8 pages. Read section 2.9 - CONNECTION TO A VENT SYSTEM... look at the WARNING section <<-----

    IT CLEARLY STATES THAT AAVs (AIR ADMITTANCE VALVES... such as studor vent) ARE NOT ALLOWED TO BE USED ON THIS SYSTEM FOR ANY REASON!!

    Did your plumber pull a permit for this work, because he was supposed to.

    Here is what I would do. I would copy this information, then present to plumber.. see if he will make it right. If not, get on the phone with the local plumbing inspector and report this guy... HE IS A HACK! Anyone that has installed these systems know you cannot install a ONE-WAY vent on a pump system like this!!

    Here is another link showing you what this should be piped like:

    http://www.saniflo.com/downloads/ins...FR_April07.pdf Check out page #2 of 12... ignore tub vent.

    This 1.5" vent as presented at last link needs to run to a FUTURE VENT in basement (if present...would be 2" fitting clearly marked as a vent) or will need to run upstairs and connect into vents at least 6 inches higher than highest fixture on that floor (kitchen sink.. )... OR it needs to run up to attic and connect up there... OR it can also penetrate the roof (increase to 2") by itself.

    So see... you were right!! Good for you!

    Hey let me know what you think... glad to help here... Mark

    IF THIS HELPED PLEASE RATE THIS ANSWER. THANK YOU.
