so i'm in a rental house, cleaning up after some tenants left. it's totally empty. before they left they told me, "the master tub has been leaking a bit. nothing major." i remembered having to replace that cartridge before and they discontinued the model, and i had to improvise with a model close to it. but alas, the close-to cartridge apparently wasn't cutting it. so i popped off the silver plate that holds the bath knob. yep leaking. i cut off the water main to the house. no water. then i used some pliers to try to pull that plastic cartridge out and it broke off inside the copper value. terrific. i cannot turn the water to the house back on until i fix this now. no wet-vacuuming carpet, no pressure washing, no watering the lawn, nothing. totally dead in the water (npi).

i called a friend who was a plumber and he told me, "if i can get that cartridge out, i'll fix it for 300. if i can't, i'm going to have to remove that granite face from your tub and replace the entire assembly and you're looking at 500. so that's the moment the tifu begins.

i can do this. i'm a fairly handy guy.

i remove the granite plate without breaking it. success! things go downhill from here. i went to home depot with some photos and talked to a 52-year master plumber and he tells me everything i need to do to fix this including buying some of this pvc glue and primer. that will become important later.

i am about 60% of the way through kicking this thing's ass, everything is going swell. i put some pvc primer on my next to last piece of pvc for the assembly. then i looked down and the entire bathroom floor is purple. that's right. purple. guess what color pvc primer is? 

pro-tip: when doing home improvement projects, do not kick over an entire can of pvc glue primer. now you might be thinking pvc glue is thick and viscous and shouldnt make a huge mess and you'd be right. pvc glue primer on the other hand, is the consistency of water. except, that it unlike water it melts everything plastic or rubber it touches... like your shoes, and your cell phone.

oh shit, shit shit! this stuff is everywhere. i start feverishly trying to clean it up. everywhere i step is leaving a black shoe print because the black rubber is melting off the bottom of my shoe and sticking to the tile floor. plastic home depot bags are melting. my cell phone case is melting. the electric cable that is plugged into the wall socket is melting. i'm panicking.

welp. it was about this time that i learned, if you get pvc glue primer on your hands, you have about 15 seconds to get that shit off before your night begins resembling the acid burn scene from fight club. ow. ow. ow! ooooowww! dammit! owww!

i flip on the faucet. oh, yeah. i turned off the water main. where is water, where is water? sigh... yes. the toilet. not my proudest moment, i will freely confess. but your pride goes right out of the window when your skin is smoldering. i run to the other bathroom's toilet which i, mercifully, had not used and began furiously scrubbing my hands with dank, nasty-ass toilet water. i should have been disgusted, but i wasn't. all i could think about was my cell phone melting. the power cable it was plugged into melting. the carpet i had just run across with melting rubber soles.

while rubbing filthy shit and piss water all over my hands, i had a moment of clarity. the one sliver of solace in this entire ordeal, "yep. this is going straight on tifu when i get home."

the story does end happily. after about an hour of clean-up, i managed to finish the repair and save several hundreds of dollars at least, but certainly not without a different kind of cost.

tl;dr while replacing a tub faucet, i accidentally kicked over some pvc glue primer and it started melting my cell phone, shoe soles, electrical cords. i got it all over my hands and it burns when that happens. had nowhere to wash it off except the toilet.

TIFU when I thought, "I don't need a plumber, I can fix this."
