I can see that could be useful where there are too many elbows in a small diameter pipe for a regular snake. Anyone have experience using pressure like this?
d first. And also what's a reasonable high pressure limit?
ere are 4 elbows before it gets to the main house drain. I was able to cle ar out part of the piping with a small diameter snake, but not all. Eventu ally got it cleared out alternating boiling water, then flushing with hot w ater, then drano, water flush, snake, etc. Also make a tight connection fr om the hot water faucet to the 1-1/2 standpipe and ran it until it flowed n ormally. All this worked, but it took a lot of time.
I bought a CO2 powered drain unclogger; it uses the same CO2 cartridges tha t I use in my seltzer bottle. Works pretty well but I have to cover the ven t hole in the sink with a wet rag.
