Hi… this flush mechanism does not work well at all. The super already replaced a part inside the round thing on top, but it makes no difference. Most of the time the handle will not engage in any water releasing activity… Should I replace the entire flush mechanism or the entire toilet? What would that cost and can you recommend somebody for what I think is a small job?

  1. It’s definately a Delaney flushometer. Get rid of it. Sloans can be repaired forever. Dealney’s are garbage. I’ve been installing and selling flushometers for over 30 years & I never liked Delaney. Just don’t tell my rep I said this.

  2. Thanks so much! Any recommendations for a local plumber? Perhaps even one who works on a Saturday? The super is not available to do this. I really appreciate the comments.

  3. I have an apartment building with these flushometer type toilets, and have needed repairs on several of them over time. The repair kits generally do the job, but the super already “replaced the part inside the round thing on top” (probably the vacuum breaker), so might not need the whole kit, may just need to replace the handle. The handle can wear out and stop making a good connection where it opens the valve. Try DIY (~$20 part) or get the super to change the handle before you spend a lot of money on a bigger job.

  4. See what master plumber says. Yes, there are rebuild kits – partial rebuild kits and entire rebuild kits. The super probably replaced the diaphragm (which usually does it; the hole on the diaphragm clogs with debris).

    The time that the rebuild kits do not work is when you open the unit up and check it and find scores or corrosion in the body of the unit. Then it is time for a new one.

    I cannot tell the model for this from the pic, but it looks like a Delaney Flush Boy or Rex. When I was working with these over 10 yrs ago now, they were about $80 new. Sloan Flushometers/flushvalves are a bit more.

    If you replace, replace the turn off valve coming out of the wall; you never know when you will need it.

    Call a real plumber for this. While a lot of handymen can do this, when things go wrong with one of these or if the repaired unit sticks open and overloads that bowl, water is going to be everywhere including in your downstairs neighbors(that is a big incoming line)

  5. There are two repair kits for that valve. One is for the old-style 3.5 gallon per flush bowl and the other is for the newer 1.6 gallon design.
    The right repair kit should set you straight but there are times when repairs just don’t take the way you want them to. I’d replace the flushometer (the valve) before I’d think about changing the bowl.
