I'm new to travel trailers, just getting my first one. Plan to do the white hose and bring along a few gallons for critical stuff (like coffee!).
I see two common sizes, 1/2" and 5/8". Do you think the larger hose would give more flow? Or is there anything in the plumbing that restricts it? If the whole trailer is plumbed with 1/2", then probably doesn't matter.
Filters, fittings especially the ones, from china, with 1/4 in holes, in them and water regulators restrict flow. The plumbing in the RV is
less than 5/8 probably 1/2. Don't know but doesn't hurt to use a 3/4 in hose to the filter. I had a one inch garden hose and itf lowed a lot of water even twisted and coiled all over the yard. Can't find one for over 20 years.
I don't think you will notice any difference with a 1/2 hose from faucet to RV.
What I would like to do is insulate the hose from faucet to RV somehow as a long run of hose gets hot and sun causes little greenies to blossom and hot water into the RV.
I've tried the Blue Camco drinking water hoses, the White Camco drinking water hoses, with and without a softener and after about 6 months use, they BOTH start to provide water that makes an unflushed urinal in a public restroom smell like roses. Even enclosed the hoses in the black rubber pipe insulation and ran under my RV and still get the stink. I've got neighbors who have used the same white hose and even the garden type hoses for 3-5 years and never change the filters if they even have one, yet they never have a problem with smelly water. Had tried several outside water filters but they drop the water pressure to below 25PSI overnight. I just took off a Camco TastePur CXR90 filter that slowed the water seveal hours after installing. I've checked the main water connection so I know the smell comes from the hose.
Got my first RV 4 years ago and found out that they now have Indoor plumming. After reading all of the postings, I've come to one conclusion. Most everyone here only uses their RV for short periods and the water hoses are also only used for short times and never lay in the heat and sun too long before being drained and stored. I live full-time in my RV and may spend up to 6 months at one RV park. I'm starting to think of getting some drinking water grade PVC pipe with quick disconnects, 2 short sections of hose and use that instead of a full length hose. Might even put a T connector and 6 inch nipple with a thredded end and a cap near the faucet to use to flush the line with bleach.
What say you old sages?
