The more I thought about the way we changed the plumbing, the less I liked it. The way we set it up, there was a slim possibility that flushing our toilet could create a vacuum as the "slug" passes this toilet that could cause the toilet to flush. This could open the toilet to sewer gasses, etc.
So, Saturday, out came the rotary hammer, and out came some more concrete.
We ended up moving our supply line to the right, and the vent for the exiting toilet to the left. Our supply line ties into the sewer line "downstream" of the existing fixture, and downstream of the vent for that fixture as well. We basically rotated the vent that is seen in the previous picture to the left and brought our 3" line in on the right, into a wye fitting.
Funny/sad story. Because we moved our stack to the right, we had to adjust the connection above, where the horizontal pipe tied into the vertical stack. Cut the old ell out, and added more horizontal pipe. As I was getting ready to add the horizontal extension, I took the glue, swabbed the coupling and the pipe end, put the glue cap back on the glue can, and pushed the coupling home. Then I took the extension piece, primed it and the coupling and grabbed the glue. Swabbed the connections and instead of putting the glue cap on the glue can, I dropped it, clean as a whistle, right into the open vertical stack... Put the extension pipe on and looked down at Tin. He says "did you just drop the glue cap down the stack???" As I realized what he was saying, the scene played back in my mind - this was no "oops, it slipped" accident. I had the cap in my hand, and had just swabbed the coupling. The swab was horizontal - cap lid vertical, I rotated the cap in my hand to put it back on the can, and dropped it right down the stack, just as if the stack was the can itself... DOH!!!!
Prior to all this plubming rework, we'd have been able to take the cover off the tee below the toilet and pull the cap out. Now, our connection is downstream of that fitting...
We looked down the pipe - nothing. Tried using a magnet on a string - no joy there either.
Finally remembered we have a 25' vacuum cleaner hose that's small enough to fit down the stack. A little coaxing to get it to turn the 90 at the bottom of the stack and in 2 tries I pulled the glue cap back up the stack.
I suffered the indignity of lot's of side-long glances for the balance of the day.
Got the concrete poured in over the excavation, and after the concrete has cured, we're going to pour in some floor leveling compound and go back with some simple resilient floor tile. The bathroom previously had ceramic, which is actually harder to keep clean in an industrial environment. Allowing until Tuesday should be 72 hours of curing - sufficient, I believe.
We spent the balance of the day confirming the slope of the sewer line is correct and adding additional support straps to prevent sagging. Also "threaded" the water line along the same path, up to the point where we'll tie into the building source.
Sunday, we got a late start, and the mojo to work in the heat just wasn't there, especially after discovering the gate valve ahead of where we wanted to tie into the building water doesn't actually shut off.... I HATE GATE VALVES.
I suspected this in advance, and opened a faucet at the end of the line and watched it for what seemed an eternity - not so much as a single drip... Cut the line about 8 feet from the valve and the downstream end suctioned empty as the water flowed out the open faucet. Upstream line drained, and drained, and drained... It's 3/4" copper - 8' of 3/4" copper should hold maybe 3 cups of water. Stupid gate valve wasn't closing off fully. Muscled it as much as we dared and got a little flow reduction. Finally just decided to go for broke - fitted the "T" to the downstream side and soldered it in place. Lifted the line at the valve to get it to drain, and then lift it where I wanted to install the "T", and got the connection soldered successfully on the first try. Ran the primary service in 3/4" SCH 40 PVC, so I added a ball valve at the "T" so we can cut the water off to our space should the weather turn chilly.
Worked on a few more small chores and went home at 2p to take a much needed Sunday-afternoon nap.
Had a chance to speak with the new business owners, our new neighbors. So far, so good. Only gripe so far is his workers like to blare the stereo, and while the music isn't objectionable, I get tired of loud music after a while. We're rarely there during working hours except for Saturdays, so we'll take a wait-and-see attitude to tell if while at work in our space we can hear their radio at an objectionable level. If so, we'll deal with it at that time. The good news is that they fully understand that they cannot obstruct the path to our space at any time. The owner's a nice fellow and didn't seem put off at all when I used the "24/7/365" phrase when explaining that even though we're "usually" only here on the weekends, we might show up at any time on any day, and expect to be able to get to drive straight thru the gate and up to our shop door with no issues.
The only "problem" so far involves the landlord telling the new business owner as part of their lease they had shared access to the trash dumpster. This is a dumpster that we pay for 100% and as a courtesy allowed the landlord to use. It's 4 cubic yards and we rarely generate even 1/2 a container's worth of trash on a weekly basis. Previously, the landlord paid for a dumpster, which was sited on the other side of the property, a good 150 yard walk from our space. Last June, in response to a City of Houston citiation, we built an enclosure for the dumpster, at a cost of over $1,000 in materials. Prior to that, on occasion, strangers would make anonymous trash contributions, but never in excess. After the fence went up, every single week there was a couch or mattress or other piece of furniture... Plus, the landlord's bill-paying practices usually resulted in service interruptions.
We decided that for the price, arranging to have our own dumpster would be the best deal. After discussing with the landlord the need for the trash company to have unlimited access to the space and obtaining agreement, they decided the time was ripe to exit the deal they had with the other trash service. Apparently their contract was up. They said - "we'll just pay for this dumpster" and I said "OK", never intending for them to pay for it at all. They've never asked where the bills are, and we've had the dumpster for about 2-1/2 months now...
Obviously, they can't offer something they don't own, so we'll have to take this up with the landlord. This is not the fault of the new tenant.
Time will tell here. The new tenant seems nice enough, but truly, we're in the beta-test phase of this arrangement. I've been in situations like this before, and the best results were always had by keeping the lines of communication open and not allowing transgressions of any sort - and by being a 100% outstanding neighbor ourselves. If "people" know you're not one to tolerate BS, they're less likely to toss it your way...
The only items on the list before we can start moving equipment back in are finishing up the metal wall between our space and the rest of the building. I stupidly agreed to do this for the landlord. He's providing the materials. The irritating part of it is that this is his problem, not ours. We're completely sealed up and separate from the rest of the building, but you can see our buildout above the 10' metal wall that separates the space. Being tired and cranky on Sunday, I had a little rant about why we should have to do this at all... Of course, the bathroom wasn't our issue either, but having a nice, clean, A/C-Heat'd restroom will be a big bonus, so I don't mind (much) the expense and effort. We get nothing out of extending the wall except dehydration...
I'd like to finish out the bathroom before moving equipment, but we've got so much stuff up in the loft that we're space confined and don't have the floorspace to set everything up. Gotta get a lumber rack built, that will allow a bunch of the lumber in the loft to come out and will open up a bunch of space. Guess the bathroom will have to wait.
More updates as updates are needed.
