Urinal Spud

[mferris72]

I have a Kohler urinal I'm trying to install and am having problems installing the spud for the flush valve. The hole in the top measures 1-5/8". I have is a 1-1/2" x 3/4"" spud. it will not tighten down without bottoming out and pops out. I do not see one bigger available. What size do I need? Should it support the weight of the valve without mounting the pipe for support? I'm also having trouble getting the nut to hold the 3/4"tube for the valve. Came with a blue seal and fiber washer. Bottoms out before it's tight. any help would be appreciated.

This is what I have. Standard Urinal Spud for .75" Vacuum Breaker Tube | KullySupply.com Says it’s for a 1-5/8” porcelain hole and a 3/4” vacuum tube which is what I have. Like I said both are loose and will not tight enough.

There should be a vaccum breaker at the top of the tail price were it threads into the flush

I would buy kohler parts for the spud sometimes those generic parts can be just a little off

Are you using something to hold the spud in place while you tighten down on it you can cut slots on a 1/2 " ips nipple
Then you can hold back on it
Have you compared the spud you took out and your new one ?????

 

[mferris72]

I do not have the original spud. I picked this up a few year ago to install in my shop. I do have a spud wrench I borrowed. Problem is I tighten it all the way until it bottoms out on its self. It snugs down but not enough to grip the porcelain hole. Acts like it’s to small. Next size I see on line is 2”. Hole is 1-5/8”

This is the other problem I have. The 3/4” end of the vacuum breaker does not hold tight in the hole in the spud once tightened. The secs say it for a 3/4”, but hole measures 7/8”. I suspect I have the wrong spud, but specs say it’s correct. P/N for spud is 101071 from Kylly Supply. (See picture) . Neither end will fit properly. Porcelain end or vacuum tube end. Like I said hole in porcelain is 1-5/8” and vacuum tube is 3/4”. Any help on what spud, tube etc... I need?

Try brand name spud we had generic spuds and sometimes they would pull out of the floor fixture if it's a kohler buy koherl if that's a sloan by sloan

 

[Geofd]

It's possible that there are model #s on the back of the urinal if so call kohler they can get you excact parts

Tried that. They must be on limited staffing for COVID. Just put on hold for a long time.

It is very important the the spud and urinal are 100% dry , if there is any water it will act as a lub and it will slide out .

Your options are try a kohler spud not an off brand or try your local supply houses me have probably hundreds of urinals on campus and we have I think 3 different spuds for different aged urinals the one you show is our most common we use koherl spuds

 

[mferris72]

Last question. Should the siphon tube slide into the spud snuggly. Mines sloppy and does not supported itself even once the nut is tight. It’s about 1/16” smaller then the hole. The seal doesn’t hold it.

 

[Geofd]

Yes there should be a chrome nut with a black rubber washer and a red friction washer use some food grade clear grease on the sofa threads and any were else there is a threaded connection that chrome nut and washer is sold in a package with the chrome escutcheon that covers the spud

I suspect I have the wrong spud. Not only is it loose before I tighten the nut, but it’s still loose and I can pull it out when tight. I have the rubber washer and fiber weather but they aren’t enough to hold/seal the tube. I’m going to my local pumping supply house today.

For urinals they make an 1-1/4x3/4 and 1x3/4. You may have the wrong one.

Hummm. I have a 1 1/2 x 3/4 spud. The hole in the top of the urinal measures 1 9/16. When tightens down it will not stay and pops out. Kinda of at a loss at this point.
