Especially in older houses that were built disregarding code and common sense. On the 10th we had a blocked drain while I was giving one of the dogs a bath. Drove up to our little tiny dollar general and tried finding the enzyme type clog buster. Had to settle for drano. Put just a little in and let it sit. Clog loosens up but the drain stays slow, we can live with a slow drain until I can get into town to get the enzyme, no problem. Done that before. That is until hubby takes a shower that night. The adjacent half bath floods. We get it mopped up and decide to work on it the next day because it's already late and I was exhausted. Next day I start by cutting an access panel big enough to actually use under the half bath sink, the one that was there was only 6"x 4" (WTH?) and find the area still flooded. Out comes the shop vac, glad I spent money on the thing now. Get everything cleaned up and start testing to see what's leaking. Turns out the drain assembly is not actually connected to the drain that goes UNDER the foundation, it's just sitting in it, no rubber boot, no reducer, nothing, so everything that's going down the drain is just coming right back out. Call hubby, ask him to borrow a pipe snake from work. He brings home the snake, wrong type, will not fit into the drain at all So for the next few days as I am not going to be home long enough to figure it out we decide to utilize his empty bathroom at work for showers. Hubby has NO clue what he's doing with plumbing, usually ends up destroying what he's working on in the process so it's something I do instead. (he gets the electrical stuff) Fast forward to the 17th after I get the silkies home.... I find a pipe snake that will work while I'm on the trip so I start trying to negotiate the drain from the tub side. Finally give up and decided to take all the connections apart on the 18th. Get everything apart and cram myself under the tiny sink where I can't get my head over the rain because there's a stud in the way. Unleash the pipe snake.... get only a foot to a foot and a half down the drain and can't get further. If we were off grade I'd have already been under the house and had all the pipes removed, cleaned out and put back together. But NOOOO we are on a slab. Give up and call a plumber, several actually but only ONE even bothers to return my call. He comes in about 6 Friday evening and takes a look, gives quote and says he can be back Monday morning with the equipment. So this morning they come in and it takes them 2 hours to get to the clog because whoever built this place put a p-trap to freaking close to the outlet drain for the tub and it's impossible to negotiate with even the expensive rotorooter machine they bring in. He decides to go in from the sink drain only to find out that whatever idiot repaired it last time use straight connections with PVC and glued them all together instead of buying a sink drain kit that screws together for easy access. He cuts it apart and finally reaches the clog. 20 feet down along the drain. And we still don't have a clue what was clogging it either. He gets everything put back together and adds that rubber fitting to the drain out like it should have been before so it shouldn't flood again unless the brass pipes or the boot burst. The entire time they were here, the cats were in the tub smacking at them through the overflow hole. They got a kick out of the brats, especially when I had to start giving commands like 'sit' and 'leave it' to get Nod to leave them alone. Bill was $100. The helper is coming back this evening to pick up some chicks too!!
