Any ways to silence a pressure assist tank?

    After the umpteenth shipment we did get an A/S Yorkville that actually worked and wasn't shattered. Wow. Anyhow, since a half year or so that means we have a guest bath again. But that pressure assist tank is really noisy. One of our dogs takes off in a panic whenever the royal flush cometh. I guess it's also embarrassing for guests when they push the lever and then "KAPOW ... VROOOOSH". Archie Bunker's toilet at 704 Houser Street (All in the Family) was nothing compared to a pressure-assist.

    Are there any tricks of the trade to quiet them down a bit?

    Short of replacing it, none that I know of.

    Thanks, Cass. Looks like we have to live with it then. I don't want to go through that botched-delivery ordeal again. It was a nightmare to get one that actually worked.

    Maybe I try something with pressure reducers. At least that ought to muffle the "vrooosh" part of it.

    Regards, Joerg.

    Why do you need the pressure type toilet?

    Most rear outlet floor mount toilets are pressure assist now.

    Briggs does make a gravity version, that uses the vacuity tank fittings.
    I know they say vacum, but it sure works like a 2" flapper gravity in practice.

    Thanks, Terry. Interesting, maybe I could try that other tank on it. It's not much of a problem in the hallway where the guest bath is. I remember you mentioning that your Glenwall can be heard from a few miles away as well :D

    But I'd hate to have one of these in our master bath. Getting older means having to go at night sometimes. Then, KAPOW - VROOOSH.

    Regards, Joerg.

    Closing the seat before flushing can help, but pressure assist toilets are noisy by the nature of their design.

    From the FAQs published on the Flushmate Website:

    It's not really an answer to your question but it does explain the noise level in a logical fashion.

    Thanks, Scott. I had read that one. Much of it is IMHO marketing fluff.

    "... a careful balance is established between the volume of water passing through the jet to evacuate the bowl ...". I don't see that happen. The jet wins every single time. In view of the dimensional "accuracy" I have seen I can't imagine how they want to control that.

    "Our testing has shown that while the peak noise levels generated by a pressure assist toilet may be slightly greater than with a gravity toilet, the noise level builds up and drops off faster with the pressure assist system." Yeah, right. That is not the case here. "...slightly greater ...", that almost made me roll on the floor :)

    Some day I'll try a pressure reducer in front of it. Won't stop the initial KAPOW but it should help with the VROOOSH part of the flush. But many of the ones in the hardware stores have that dreaded weep hole and I won't use those indoors. They always say they won't leak and then they do anyway.

    Regards, Joerg.
