I have a clogged vacuum line and have a couple questions about un-clogging the line.
1. Is the Peterson Canvas HydroFlush any better than the Drain King?
2. How long can it take for hydro-flushing take to work?
3. I read if you try flushing from the pool to pump to turn on the pump to provide suction. It that safe?
4. Is it possible the clog is at a valve and can be resolved by taking the valve apart?
As always any help appreciated!
Thanks in advance
