Mini screens ? Or add petcocks.
Dont drink water from the holding tank, use bottled water.
I have access to holding tank which is under my bed.
I cut an 8” hole in the top of the tank to match a marine deck plate that i installed to cover the 8” hole.
I unscrew the deck plate to allow me to reach inside the tank to clean it. I could not believe how much slime i wiped off that interior plastic and i always sanitized my tanks with bleach as suggested. Bugs always find their way into holding tanks thats why i never drink that water.
