Need ideas on water storage

[rafatoy]

Hello all
Need ideas, I am no plumber, so be nice...lol...i have 30gal barrels set up for RO/DI water if you can see it has rings around the top to make a good seal with the lid. Here the problem when I take out water from the nozzle, water come out great, ( the flow) than within minutes the water slows down to than none. I am stuck? What's wrong? How should I fix it?

is air going in to replace the water as it leaves?

 

[rafatoy]

Opps no air going in its completely sealed.i don't want any particles going inside so what do I do?

Could you put a small valve in the top to open so you can take in some air as it drains? I'm thinking along the lines of how they put that vent cap in the top of liquid laundry detergent.

You need at least to have a either a hole in the top or a valve for air to enter. I guess if you are that worried about particles from the air, you could use an air filter.

Air valve it is, gonna find one or maybe shot air from a air pump?

Yeah you just need a small hole in the top for air to get in there.

Found the solution;
Added air admittance valve to the lid, works great..... Yes I painted the top blue, originally it's white in color!!!
