which size drinking water hose?

Got my new trailer now accessorizing. 1/2" or 5/8" water hose? which would you recommend? will it make much difference one from the other? thanks in advance.

    Will not make any difference. Every water source in the RV most likely feeds through a 3/8 inch line. Two 3/8 inch lines are less than a single 1/2 inch line. So unless you need to take a shower and wash dishes at the same time, 1/2 inch is all you need.

    At home in the sticks and bricks world you only have two places in the home that feed through 1/2 inch lines. The tub and the washing machine. Every thing else feeds through a 3/8 inch or less supply line.


    Your main lines running through the camper are most likely 1/2 inch. When they feed into your faucets they go down to 3/8 inch.
  • Having a pressure limiting device is much more important than what sized hose.

  • Either one but I recommend filling your tank and using the pump. Pressurized RV water lines can cause a disaster.
