Although I'm a big fan of rhizome pruning, there's no guarantee you'll always get everything the first time. This usually isn't a problem...you just go after the straggler you missed. However, in your case, the first time you might see this straggler is when it comes up through the pool. Bamboo can penetrate things much thicker and tougher than that liner. I'd say your safest options are: clumpers, runners in pots, or planting a good distance from the pool.

Thanks so much for the pics and I am sorry that I could not get back to you sooner. They are excellent photographs and I have several more questions starting with "Who keeps that shower so CLEAN??" THAT certainly doesn't look like a shower that someone has been using for 2 months! Especially a little son capable of sitting on top of the drain and stopping it up! I re-read your thread on "Before and After Pics" and I have scanned (not absorbed) the ADA shower installation guide, as well. I realize that my decision will be personal, but by looking at the example you posted of the threshold, you obviously did some soul searching, as well. What swayed your family to go curbless? Also, do you think, or does anyone know if a channel on the floor is likely to collect 'gunk', more than the 'glass directly to the floor' application? I must confess that I am new to the Forum, and new to the internet, and I have spent the last hour trying to figure out how to post images. I had some photos to show of my remodel, but I can't figure how to get to the screen that allows my pictures to connect to this message. When I went to "Galleries" that still got me nowhere. I'll get my 'whiz kid' daughter to help me tomorrow. Now, if all you veterans out there can manage to quit laffin' at the 'rookie' long enough, maybe together we can solve the 32 questions on my remodel that I need help with. :) One more of which is I am torn between completely enclosing my shower seat (as you did, Vern) and leaving it open because it makes my shower appear larger, and gives me a place to swing my feet. But then there is the question of the floor drying underneath after finishing your shower, and squatting under there to keep it clean and mold-free. Any thoughts? If I could have posted my pictures, it would have illustrated this! :)) Mongo, As usual, you save the day. I will look into the 'shut-off' device using the link you provided, but I don't know if it will work. We have no basement; we live in a single-story in Texas. But don't relax yet, I have more questions for you, too. Just give me time.

I did receive a quote for a 5-ton geothermal heating & cooling system from WaterFurnace for $23,158, but it did not cover my swimming pool. They said to add an air source heat pump for the swimming pool heater which would run another $5,000. I didn't get the feeling this system would help my electrical costs for my swimming pool pump or hot tub. Am I wrong? Also, since my hot water heater and fireplace run on propane, I would have to replace the water heater, and continue to run the fireplace on propane.

Unions, directing the pressure relieve valve drainage, overflow pans, are rarely code issues, but are "quality of installation" things. It's possible that the cold water shutoff to the tank has a leak. I've seen brand new shutoffs not be able to fully shutoff. It's also possible that the guy melted the valve guts sweating it on.
