One of the things that us home inspectors love about our job is that we get to point out what's wrong, recommend repairs, and then we're done.   We don't have to worry about exactly how the repairs are going to happen, and we're not the ones that have to do the work.

When we take on our own home improvement projects, we don't have that luxury.  We've gotta do it right, and figure out how to get there.  I rarely tell personal stories, but here goes one.  This is a blog, after all.

UrinalI moved into my home in Maple Grove about four years ago.  It had an unfinished basement when I moved in, and the basement is still unfinished today.  I'll get around to finishing it someday, maybe, but for now this space serves as my office and exercise area, and I spend a lot of time down here.  There's a rough-in for a bathroom, which consists of drains and vents for a toilet, sink, and shower or bathtub.  Pretty standard stuff for any newer home with an unfinished basement.

When I finish off my basement I'll add a bathroom, but I thought it would be great to have a urinal and a sink down here in the meantime.  I figured that since the drains and vents had already been roughed in, all I'd have to do would be to run some water lines over, connect the fixtures, and I'd be all set.  It shouldn’t take more than a few hours, and would be a temporary installation, but I'd make good use of the fixtures while they were installed.  I've thought that ever since I moved into this house, but I finally took action a few weeks ago.

I had been passively looking for a used urinal on Craigslist for many years, but I was going to be home alone for a few days, and that was my chance to get a project done.  You know, a nice surprise for my wife when she got back.  To get things moving along, I went online and special ordered a urinal from Home Depot for $118, and a flush valve for $92.  For the sink, I went on Craigslist and found someone selling a sink base, sink top, and a faucet for $50.

I got the project done, but it took me a little while longer than I had planned.  I’m sure any good plumber could have knocked it out in a few hours, but I’m not a good plumber.  Heck, I’m not even a bad plumber.  I know wrong when I see it, and I know how stuff is supposed to look when it’s right, but installing a urinal is brand new territory for me.

Water flow

First off, I spent way too much time installing the water supply lines.  Urinals with direct flush valves require at least ¾” water lines (see section 4715.1730 of the Minnesota State Plumbing Code), because there needs to be sufficient water flow to get a good flush out of the flush valve.  It's not like a flush tank, where a large amount of water is available to quickly dump.

Whenever I see PEX tubing installed, I’m a little annoyed at the number of fittings that are used.  Every one of those fittings restricts water flow, and part of the really cool thing about PEX tubing is that it’s flexible.  You shouldn’t have to use a bunch of fittings to get the PEX tubing to go where you want it to go.

So of course, I killed my back standing on a ladder bending and pulling ¾” PEX tubing through my floor joists and through the top plate of my wall.  Check out the photo below; you’ll notice there are no fittings used.

No fittings

I was tempted to use 90-degree fittings to get the PEX where I wanted it, but I persevered and got it all pulled through with no fittings, just to make absolutely certain that I wouldn’t have to worry about water flow.  It turned out to all be a waste of time and effort.

Once I gave the urinal the first test flush, water came out so fast that it shot right over the end of the urinal and all over the floor.  I adjusted the flow on the valve down about hallway, and the same thing happened again.  I adjusted it down again… same thing.  I ended up adjusting the flow all the way down to nothing, then gave the adjustment screw a quarter turn open.  That was about perfect.

Lesson learned: plumbers know what they’re doing.  Fittings in PEX aren’t a big deal.  The water flow probably would have been fine with a hundred fittings installed.

Boring holes

Box splicesWhile making the bore holes in my floor joists for the water lines, I made sure to stay the heck away from electrical wires.  Or at least I tried.  I made note of some wires that were in the path of where my water lines needed to go, pushed them aside, stapled them up out of the way of where I would be drilling, and drilled through my joist into the back of another wire I forgot about that was on the other side.  Duh.  Ultra-rookie mistake.

The good news was that my circuit breaker did its job and tripped the circuit, and I only put a tiny nick in the tip of my drill bit from the electrical arc.

So that’s what the two junction boxes at the ceiling are all about.  Lesson learned: look twice, drill once.

Watch it, sparky

I wanted the water pipe coming out of the wall for the urinal to be sturdy, and the right way to do this would be to use a ¾" drop ear elbow, but all that I could find at Home Depot, Menards, and Lowes were the ½" fittings, so I stubbed out some ¾” copper tubing and fastened the tubing to one of the wall studs with a few home-made brackets.  Not perfect, but it worked pretty well and the pipe doesn't budge.  One of my screws ended up protruding through the wall stud a little bit, so I got my angle grinder out and used it to cut the screw off flush.

Sparks on urinal

I didn't worry about the shower of sparks shooting out from my grinder onto the new urinal until I noticed a million little black flecks that showed up on the top of my brand-new urinal that wouldn't come off.

After coming up with no solutions on Google, I used Scotchbrite pads, SoftScrub, and about a half hour of very hard scrubbing to get the black flecks to nearly disappear, but they’re still not completely gone, as you can see in the photo below.  It almost looks as though the surface of the porcelain is pitted, but it still feels perfectly smooth.

Blemishes on new urinal

Lesson learned: keep sparks away from porcelain, or any other nice surface you don’t want ruined.

Summary

I’m sure I’ll end up re-doing everything except the water supply lines when I finish off my basement, but this sure is a convenient addition to my basement for now.  I've shared photos of residential urinal installations on the Structure Tech Facebook page, and one of the more common comments I received is that urinals are either gross or messy, but I couldn't disagree more.  Anyone who thinks they're gross is probably comparing them to public urinals.  Sure, the areas around those can be gross, but when the urinal is in one's own home, one has laser-focused aim and there is absolutely zero mess.  Liquids go where they're supposed to go, and nowhere else.  There's nothing not to like.
