I'm having problems with my plumber, he instaled a old flush valve in my basement washroom, ran a dedicated 3/4" line and the valve dosent work ( it's an old one that leaks like crazy) but now he can't find a valve and toilet combination that will work with a 3/4" residential line. All the new ones need the water volume of a 1" line. The walls are all finished and I really don't want to pull off all the tiles and refinish the walls, does anyone know of a valve and toilet combination that might work? Thanks.

You aren't going to find a 3/4" flushvalve capable of flushing a water closet -- Especially if it's an older pre-low consumption model.

At this point, your best bet would be to find a competent Plumber who is capable of rebuilding what you already have.

BTW, where exactly is it leaking from?

And can you upload a picture of the flush valve and the toilet?

I'm guessing your plumber isn't really a plumber. You can step down or up any pipe but 3/4 seems way big to start with let alone a 1" pipe. Most water closets are supplied with 1/2" supply lines that step down to 3/8" at the stop cock. Angle stop cocks come in several sizes and one should meet your needs.

All of the flush valves that I've installed back before I retired have been supplied wit 3/4". There's a lotta volume in a 3/4" line. What's the major problem in bushing a new flush valve down to 3/4" and installing the new valve off the 3/4" supply? Regards, Tom

He's talking about a wall mounted flush valve.

Thanks for the reply, the valve is leaking from the handle, its an old Galt Brass Co. valve. The reason I wanted to use it is because the bar I drank in for 3/4 of my life closed, so I bought all the fixtures in the place and am re constructing it in my basement. The urinal valve is the same, and it works perfectly, so I wanted to keep the look the same. Are there any cool old toilets with the elevated chain pull tanks out there? I will try to post the pictures I have of the valve but it may take a bit. Thanks again!

The diaphragms in the newer low consumption flush valves are pipe size specific.

Meaning it won't pass enough water through the diaphragm to properly flush the toilet.

Crap! I really appreciate your help!

You may have to settle for a less than historically authentic solution to your problem.

If it were me, I would take the handle from the urinal and install it on the toilet flush valve and then buy a new flush valve for the urinal.

You could also try looking into seeing if there are any recycled building supply retailers in your area to see if they have any Galts lying around gathering dust on a shelf.

I thought about replacing the valve from the urinal, but it still dosen't fix the problem of in sufficient water volume.

Are you using the original toilet as well?
