Boy am I going to have to get you guys trained... Ok Class here is the good stuff.... Now I use RV Water Filter Store because of the quality of the product. If you can find something better, let me know.
To prevent having to put stress on the UDC shore water connection I use a 90* brass quick disconnect:
Kwik Link Connect System - 90 degree - Attachs to your RV's water inlet for faster hook-up and a leak-free connection. New design high impact copolymer body with stainless steel male fitting, they come with a Parker female coupler, a dummy plug to protect hose end, and a dust cover.
I use a 1/2"
4ft hose to go to my water filters I got from Lowes. I use 2 of the Westinghouse water filter canisters. One for a Black Charcoal filter and then the second is a White filter for general sediment.
I then connect a
36ft 1/2" hose. These hoses are non kink and stand up to 120 PSI. Why a 36ft hose? Well it seems that some campgrounds are built with a different concern or logic, but I have found that the 36ft hose will connect to about any shore water almost any where it is located. However I do have another 15ft of the same hose just in case, but never used it yet.
Next I connect to a
Watts Brass Model N55BG Adjustable Regulator,
1.5" dia-meter 0-160 gauge, 6-9 gpm
Now I use another 4ft hose to go from the regulator to the water faucet. Why?!! Well while up in Kentucky we stayed at Grandma's RV Park. To keep the water from freezing they put the faucet down about 18" in a large, about 10" PVC Conduit. I could bearly reach down and screw on the hose so I had to use 2 - 25ft hoses with the regulator in the middle. Now the 4ft hose works great everywhere.
I use quick disconnects on all of my water connections except for the shore water faucet, don't want to leave one everywhere we stay. Could get expensive and you birds would probably swipe them... LOL
