• Make sure you drain the tank completely between
uses. Water left in the tank causes rust, mineral deposits
and algae buildup.
Put the trailer on an incline with the rear slightly lower
than the front so that all water will drain through the
drain plug. Then open the faucets to let out any water still
in the pipes.

Cleaning the tank regularly will improve the taste of
the water and keep the tank safe to use when it’s needed.
So follow these tips to keep your drinking water from
tasting slimy, rusty, or metallic.
• Close the manhole
cover tightly when
the water trailer is in
storage. That keeps
out dirt, sand and
rainwater.
• Before filling a tank with drinking
water, eyeball the weld joints inside the
tank for signs of rust. Scrub away any
rust with a solution of water and scour-
ing powder, NSN 7930-01-294-1116.
Always use a nonmetallic, nylon brush
such as NSN 7920-00-061-0038, to
avoid scratching the tank’s inner surface.
Flush the tank thoroughly with clean
water. Then scrub it again if you see any
more rust.
• Every three months, pour 8 gallons of vinegar, NSN 8950-01-079-3978, into the
tank and leave it for 5-6 hours. Then empty the tank and flush it out with clean water.
The vinegar kills algae and prevents deposit buildup.
Since algae is a bigger problem when it’s hot, clean the tank more often during
the summer.

too late…
