Any ideas how to get an old commercial drain open? I've tried both a 25' snake and hot water with no luck. It's in an old bar so there could be anything in there. I'm thinking it's food, broken glass and plastic straws are blocking the pipe. Pic unrelated.
like what an underground drain?
if its not underground you strip it down and clear it out.
if its underground you get a drain rod with a big rubber flappy disk on the end that fills the pipe then you pump it in and out of the drain acting like a kind of plunger but with a 2-3 ft stroke length. keep a hose running to wash the shit away. pump until it loosens out to travel further down and become someone elses problem.
Would that work to clear out any plastic or glass that is stuck in there? It's an old building with metal pipes so I don't think strong acids would be a good idea.
It's underneath the bar so it's in a pretty cramped space. Never seen one of those things in any hardware store either.
I'm considering getting something like pic related. Anyone have experience with them?
a drain cleaning company will use something on the same principle as your picture except that they don't attach it to a hose they use a gas powered pressure washer type contraption that is very very high power and high pressure and actually works, i don't know what that will do.
pic related is for outside underground drains.
if you want to unblock a drain i would start with a plunger, the action should dislodge separate and move the blockage. keep some water running in between.
Hopefully the pic doesn't go sideways but here is what I'm working with.
Get a continouous slow stream of hot water going down the drain to warm it up. Then follow with professional drain cleaning acid. Leave for a few hours. Flush with hot water then repeat with a caustic soda solution.
Get yourself a nice, caustic acid drain opener and pour about 8oz in there, followed by hot water. I used to work at a movie theater with similar drains in our concessions and they'd often get clogged with popcorn and soda syrups.
Well that.s a floor drain, so that pitches down to a larger diameter main drain at some point. Your best bet would be to get a disk plunger down there and try and see if you can't loosen up the blockage. Worst case scenario the block is further down the main drain, and could be encased in solid concrete. Cast Iron drain pipe tends to deteriorate on the inside, and after a while a form of this scale-type material builds up, facilitating blockages. PVC the way to go nowadays
I like the way im triggered by the OP pic.
saddens me no one has discussed it yet.
band saws are great tools.
