What a day !!!!! & for once it was my own doing !!! I have a wet room with a slopping floor so the water drains away, anyway yesterday I decided to put some bicarb down the drain but only I didn't pick up the bicarb did I, I picked up caustic soda EPIC mistake !!!!!!!! The bloody stuff hardened so when i had a shower this morning the bloody water didn't drain away, thankfully I was working from home today doing some training so was able to nip to ASDA & get some drain unblocker, did it work - did it bugger ! So off again I trotted & got another make, again no difference. I then was starting to panic, googled it & there were horror stories about it being like concrete & people had, had to replace the whole "trap & pipework" because of doing the same thing. My bloody trap is in the floor & I was seriously thinking this is going to be an insurance job as the whole room is tiled ! One suggestion was to keep pouring hot water over it, so thankfully i have a carpet cleaner so was able to suck up the water so had a go at that. Nothing ! Another suggestion was to use a plunger, I don't own a plunger so off I went to B&Q. Found a plunger & there was some industrial acid drain cleaner next to it so picked that up to. It was expensive £10 !!!! So off I go starting with the plunger, an hour later no change it just wasn't budging. So i looked at the industrial thing I picked up at B&Q & looked it up on the internet. Reading about it scared me it is powerful stuff, can dissolve a human body !!!! So I'm thinking what shall i do, go for it as it is going to an insurance job anyway. So I started pouring the stuff only a small amount & straight away it bubbled up & started letting off fumes. I got scared & opened the window & left it. Went back 15mins later & nothing !!!!!! The bottle said to put 250ml down so I held my breath & covered my eyes & went for it, the bloody stuff stank & bubbled up like a experiement I used to do in science at school BUT IT WORKED !!!!!!!!!! Yay so lesson of the day read the bottle before you pour stuff down the drain or never have caustic soda in the house !!!!
