Water Flow Regulators:
Before you connect water inline (which means you are attaching a water line directly to your rig), you’ll want a water flow regulator on the hose. The purpose of a regulator is to convert a higher pressure to a more reasonable pressure. It converts a household faucet which can have water pressure from 80 PSI (pounds per square inch) to over 150 PSI.
The water lines in an RV are very thin; much thinner than in a house. If you don’t use a water flow regulator, you risk blowing out your lines. The plumbing of an RV isn’t sold at Home Depot. It’s a long, arduous process to trace a blown-out line.
So, solve the problem before it ever gets there by attaching the water flow regulator to the hose “BEFORE” you attach it to your rig.
