100 gallon reservoir tank for my RO unit on the way...

with a little customizing, a float valve assembly will be installed, so it will automatically shut off when full... ( it's only happened once or twice, & it's not like the RO unit pumps out the gallons per minute ) but I have overflowed my 35 gallon holding tank, a couple times, enough to make the floor damp...

this fits in my space, & will go down to the basement... I may make a stand for it, but will decide if that's needed when in place...

With a sturdy stand, you could have a tap and hose, if you have tanks in the basement. That was my plan before I realized how soft my tap was without RO.

Not big enough; you need at least 500 like mine Also lookup well pump great for getting water from there to here....

I went to my plumber and said i want polyp piping from my basement to my work room; and he said polyp what is that - and i said it is like flex but more resistant to leaching. He said ok how do we connect two pieces; i said well you can't glue it since it is inert you have to fuse them; and he said ..... forget it ain't gonna happen.

Geee why did i bother with a plumber....

I have a diaphragm plumbing system pump, and a silicone hose I use to fill tanks, currently, and plan on fitting those to this bigger tank
