Today I spent some time planning and finally putting in the flush kits I have had lying around for most of the summer. Since we don't have a direct way to access and flush the tanks from the bathroom or a pre-installed system, I purchased two rinse kits off Amazon.
For the grey tank, just a standard sprayer to help clean it out, and for the black tank, the
Tornado spinning sprayer to try and keep the tank clean and loosen up anything that may have gotten stuck.... yuck!
I didn't like the simple clear hoses that they provide in the kit. These seemed a little less durable for the length and I'd rather take a few extra minutes to use the PEX plumbing piping. Another thing, I wanted to have just one point of hook up to flush both tanks, rather than undoing the hose and switching to the other while at the dump station. The last thing I want to do is take extra time when in the conga line on a holiday weekend to switch systems.

Installation is pretty simple. Clean the side of the tank where you are going to install the flush kit and lay out the template that is provided. Using a hole saw, a simple clean drill into the tank for each of the kits. Then, clean the edges up to remove any burrs and wipe down the tank wall again. 100% silicone caulk is used to seal up the kit to the side wall of the tank and the screw holes.
Then came time to figure out my valve system. I decided to have a single drop-ear mount for the hose connection that goes to a brass "T" and feed each side of the flush system as I need. Being OCD,.... yes,... I used Red PEX for the black tank and then Blue PEX for the grey tank. Nice 1/2" ball valves to control each side. Simple, and effective. Some rubber coated clamps and self tapping screws and everything is secure and ready to hold up to the traveling vibrations and regular use. I'll try to test them on this next trip when I have a site with full hook up.
