drain back up
I had second bathroom rennovated with new shower (but where old one was) that abuts old bathroom with shower and tub. New shower was tested for drainage and leaks and appeared fine. After eight showers in new bathroom, drains in both backed up. Liquid plumber and plunging have brought up hair and what looks like soil but water stays in both drains. No other drains in house are affected. Any clues?

If the drainlines are galvanized steel, it may be some dried up remains and is now breaking free. While the plumbing was not being used during renovations, the pipe probably dried out and anything that was stuck to the insides of it have now dropped into the lines causing the clog. As far as water remaining in the drain, are you looking directly into the drains? What you may be seeing is water in the traps and it belongs there. You may want to have the drains snaked or try an enzyme drain cleaner such as Draincare by Zep. Enzyme cleaners cling to and eat organic clogs such as hair. Caustic drain cleaners eat a small hole and go to the main drain, leaving a partial clog to start the whole thing over again. Good luck.

I would try running a snake down farther to free a clog.

I have yet to see a plunger clear a clog in anything but a toilet, and Liquid Plumber should be renamed to Liquid Waste of Money.

You can use a bucket auger or a hand spinner or whatever you want to call it...

Here is a link. You can get these at a local hardware store.

Read the directions or do a search online for proper technique. If this doesn't work, then call a plumber or professional drain cleaner.

Note: Be sure to tell them you have used Liquid Plumber in the drain! This stuff damages equipment and can cause severe burns. I'm sure you don't want them getting hurt trying to fix your drain.
