Your sewer line can't handle a flush of 2 gallons every few hours, but can handle a shower drain that disposes of a couple gallons per minute? 

It can easily be removed with a mold removing solution or a bleach solution (1 cup of bleach, 1 gallon of water).

If you go to the grocery store to buy a $4 gallon of milk and only have $2, nobody apologizes to you.

(I put my gym membership on hold that winter).Then, I installed industrial-grade perforated pipe that was roughly 3’ diameter (the type of thing you might see kids crawling through at a playground), and three industrial-grade sump basins, each of which were 65+ gallons (large enough for a full-grown adult to crawl into).

Otherwise, if you want a green building, then get a few five gallon buckets of green paint and go to town ... it will be just as effective in raising your NOI and at least it won't cost you too much ...

Behr “commercial” paint is about $90 for a five gallon at Home Depot. 

If you could stockpile gas at $1.59 a gallon - how much would you have stockpiled?

@Alex Huynh I have a 6-person spa and it holds 500 gallons.

They sent me one that is otherwise qualified, but has a 200 gallon saltwater aquarium weighing approximately 1750lbs.

I choose to go with Behr Premium white eggshell paint for the walls, Semi-gloss for the trim, and flat white for the ceilings.I ended up using basic paint calculator for square footage and number of coats, which lead to me purchasing (1) 5 gallon bucket of semi-gloss, 1 bucket of ceiling flat, and 5 of the eggshell.
