To those that have incorporated Urinals...

[pickles]

The trap was integral to the porcelain. I'm pretty sure that's how most wall hung units are. At the time I did mine Lowes only special ordered them, thats probably changed now. I had a friend who's a plumber that hooked me up.

Edit: Google show that some wall hung units require a trap. This Toto model for example has an integral one.

Too bad one can't go to a store and test them out.

I am constantly surprised at the poor design of many urinals. Many, nay most, seem to be designed to maximize the amount of splashing. I like the old ones we have at work. They are floor mounted and look like if someone took a regular toilet bowl, heated it up and then stretched it up, and gave it a little pinch in the sides. It has a nice deep bowl to minimize any splash escaping, and could easily be used by the ladies if they were desperate.

That would be great for a hunting cabin. The house..not so much

A urinal install requires 3 things.

1) the Urinal itself
2) the flush valve
3) a carrier

The trap is integrated into the design of the urinal, and the flush valve acts as the water supply/stop.

No one has really talked about the carrier, but you should really use one. Every urinal you have stood in front of was mounted with a carrier.

If it was me, I would go with the following 3 pieces.

1) Kohler 4904-ET-0 ("0" is the color code for white)
http://www.us.kohler.com/onlinecatalog/pdf/1116031_4.pdf

2) Sloan Regal 186-1.0 XL (1.0 is for the lowest water consumption). The Regal is the cheaper version; the Royal (which was mentioned earlier) has a longer handle and slightly different diaphragm - but it is not worth paying almost 2x as much for.

*Note- the urinal and flush valve I listed are both 3/4" top spud. Urinals have an option for 1-1/4"...make sure that you pick matching pieces.

3) Mifab MC-30 Series plate carrier. Any model from the 30 series can be used for a urinal.

If you want to get fancy, there are a few options for electronic flush valves.

First, there is the hardwired option:

Sloan ES-S (for 3/4" top spuds) but it is insanely expensive, and overly complicated to install.
http://www.sloanvalve.com/Installation_Guides/0816156.pdf

Second, there is a battery option:
Sloan 8186-1 G2 (for 3/4" top spuds)
This is the one that kind of looks like a black cap. The nice thing about it is the no-hard-wire makes installation easy, and it has a push button override. Still very expensive.

Finally, my favorite is called the Sloan "SMOOTH" 186-HWS-0.5 (SMOOTH is for "Side MOunted Over The Handle).
It is a side mounted retrofit that just slides over the handle. It is cheap, battery operated, and has a nice manual override. You would need to purchase this in conjunction with the Regal I specified earlier. To be clear, you would use this, as well as the manual flush valve.

Hope that helps.

Thanks for the info fowler, but if I added $400 hanger, that would put the urinal out of the realm of possibility. It doesn't seem the others have had a problem without them. I understand a heavy support in a commercial environment, but am thinking the standard bolts will be ok for home use.

Have you bought the urinal yet?

I am just not entirely sure they can be hung without a carrier. Maybe they can, I've just never seen it.

You might, however, be able to notch some unistrut into the studs and hang the urinal on that.

 

[IrregularPulse]

I haven't bought any of it yet. Pickles, did you use one?

At any rate, if you haven't bought the urinal, and the sheetrock is already hung, how can you be certain that no studs need to be strategically placed in order to bolt the fixture up?

Don't be scared by list prices. A carrier can be purchased from a distributer for somewhere between $85 and $100.

Mifab is not the only option. You could go with Josam, Zurn, Jay R. Smith...

Any plumbing supply house near you that caters to light commercial will have one of those 4 drain lines.

 

[IrregularPulse]

I am not seeing any mention online about using one in the installation or anything. Are carrier bolts into studs really not sufficient?

The bathroom itself has not been built. They still need to add the two walls to create the bathroom in the laundry room. The wall that the Urinal will be against has to be built off the block wall still.

what fixture are you planning on using?

See any problem with this combo?

Sloan REGAL 186 XL Exposed, Water Saver (1.5 gpf/5.7 lpf) Urinal Flushometer for 3/4" Top Spud Urinals with ADA Compliant Handle

American Standard 6581.015 0.5 - 1.0 gpf Wall Hung Washout Urinal with 3/4" Spud Size (Comes with wall hanger)

I see the Flush volumes are different. Is it ok if the valve supplies more than the urinal needs? Or is it something that may cause an overflow? I'm not concerned about the extra .5G of water each flush.


$318 Shipped.

Anyone know anything about Mansfield? Menards sells them.

Mansfield is more of a builders grade (cheaper) line of china. More along the lines of Crane, Eljer, Gerber, etc.

The American Standard product is excellent; it is on par (if not better) than the Kohler.

1.0 GPF is a good choice. I am almost certain that the flushometer and urinal do not need to match GPM - the only rule is that you shouldn't use a urinal/toilet that requires MORE water to flush properly than the flushometer allows. A 1.5 GPF flush valve can clear waste from a 1.0 GPF urinal. That is all you need to worry about.

Thanks. That is how I understood it. It seems American Standard and Sloan is the only combination you ever see. Now to see if I can find them cheaper on ebay

 

[IrregularPulse]

Just ordered
Got the American Standard 6581.015 from Home Depot for $117 shipped and Sloan Regal 186 XL for $99 shipped. I might need a drain pipe when it comes, but I've got a couple of those laying around the garage. $225 for both brand new from respectable companies. Woohoo. Now to start looking for taphandles on Ebay Any BMC will do. Unless someone wants to donate

I work for a plumbing wholesaler and you shouldn't have any problems matching a 1.5 gpf valve up with a 1.0 gpf urinal. You'll get a little extra water when you flush but it won't be too crazy and it will drain. You can always change out the diaphragm in the flush valve if it's too much. A diaphragm shouldn't cost more then $15-20.

How put in a urinal with a circus mirror for a backdrop? Makes everything look bigger...

Be sure to put in a water heater in case I ever come over. And a ladder.

 

[crash1292]

just use 5/8 plywood from stud to stud as backing and the urinal wont go anywhere....unless the wall falls down

 

[IrregularPulse]

They got it hung today. I'm expecting it to be in service tomorrow or the next day when I get home from work.

 

[pickles]

Yep that's what I'm talking about! You're gonna love it!!
