Are there any kits out there that I can install on the very bottom surface of my tank to allow me to drain it from its low point? I'd love to power wash the remaining algae off the sides and top, drain it and let it dry before the season, so a 3-4" pluggable hole would really do the trick. In the meantime, I'm flushing and filling repeatedly. I did a wash and conditioner and will start chlorine again if that doesn't work. Any other/alternative suggestions would be great too.

You’ll have to gain access to the top portion of the tank and make sure you have enough clearance and a flat section large enough to install it. Here’s another good look at a previous installation I found online that might be helpful. Evidently, this is a home-made kit, but similar to the Aqua Saver.
I installed an Aqua Saver a few years ago and it seemed to work great for that customer. The instructions state it can be installed on the top or the side of the tank, but I've seen some fairly thin-walled polyethylene tanks. I'd be hesitant to install the access port on any surface other than the very top of the tank; especially if I was accepting the installation liability. Some fresh water containers today are constructed of thin, low-density polyethylene and I'd be concerned the flexing of the sides as the tank is filled might cause leakages. But it just might be the answer to your dilemma!
