I spray each connection, hose, water filter, water pressure regulator, etc with a bleach solution in a spray bottle.
It has been asked what is the concentration for that?
General Purpose: Spray solution
1/2 tablespoon bleach to 1 gallon water
(For tabletops, toys, general sanitizing, food
preparation area’s, etc.)
For 32 oz spray bottle (1/4 teaspoon bleach to
32oz water )
For 20 oz spray bottle (1/8 teaspoon bleach to
20 oz water )
