i make my ro in the gararge also ,i put the 5 gallon containers just inside the door .if it over flows it just goes out the door onto the driveway.
not to steal your post but ,about a month ago i was doing something in my 150 gallon dt.
it is predrilled and i wanted to turn the return pipe (i took out the overflows and just put pvc to the top)well i turned the pipe a little ,i heard a pop and all of a sudden water started coming out the bottom of the tank onto my diningroom floor.
i tried to turn it back and the water really started to pour out.
i broke the rubber seal. i could get it to stop i needed help someone to hold the pipe inside and the other underneath.
wife was at work so i started to call neighbors .one didnt answer and the another was at mcdonalds.i told him what was going on .he actually got here in 5 minutes.he said he was doing 80mph down the thruway to get here to help.by the time he got here probably 40 gallons already came out .i figured i wouldnt be able to stop it .so i started emptying water from the dt to a 45 gallon tank i have to put the fish in.man i was running my ass back and forth.
well we got the tube tight and stopped the leak.by then i had over half the tank water on the floor.luckily the tank backs up to the gararge and most of the water went under the wall.and i dont have carpet just tile and stained concrete.i broke the tank at noon and wasnt finished mopping up till 8 pm.
just in time for my wife to get home from work.
thought i was safe but she saw the water in the gararge ,she came in and moved the china cabinit to find and inch of water still behind the cabinit in the corner.
show your wife this post and tell her ,at least i wasnt this guy.
i work with concrete ,work on cars and generally leave things out for her to clean up after me so .bless her heart she is used to it.
