Water Inlet

Postby StandUpGuy » Fri May 27, 2011 8:13 pm

water inlet. is there something I can use for my water intake inlet, that I might get from a local store or do I need to go RV with it? I really do not wish to make an access hatch if I do not have to.

Works okay for me and has a built in check valve. Google RV water inlet.

Why do I need a built in check valve?

The check valve keeps the water from running out when you unhook your hose. (I think that is it's purpose) I know many people also install pressure valves to keep the pressure down as some parks have really high water pressure that can cause some pipes to burst. (or so I understand.)

I installed one of these locking ones... although not sure why other than it looks a bit cleaner.

To keep pipes from bursting? I thought a check valve kept fluids from flowing the opposite direction. So this must be a pressure check then. The pipes in the trailer should not burst from city water pressure.

Stand up,

A check valve is, as you surmised, to prevent the water from going in the opposite direction.

The water fill valve is part of the water system which is pressurized by city water, or an onboard pump.
When the system is "pressurized" by the onboard pump, the water can leak out of the city water fill port if there is not a cap, plug, or check valve.

As far as city water pressure bursting a trailers plumbing; it shouldn't happen, but it can and sometimes does.
Most trailer systems are rated for 40-50 pounds, some city water systems, especially at certain times of the day can go over a hundred.
Imho, the trailer's system should be able to handle anything a house can...
To answer your initial question, yes, you can use hardware store items.
I used a 1/2" hose faucet.

I do however need a special adaptor to use a standard garden hose, since both ends require a female fitting.

I've also seen a standard garden hose run through the floor, left hanging down a few inches under the trailer (with a plug for traveling) that is used to connect to the city water source.

All in all, the RV fill is the easiest way to go.
Some prefer the enclosed lockable fill to keep people from putting something in the pipe, but most get by just fine with the exposed fill.

Thanks for that Rob, it was very helpful. I think the backflow check valve is used to keep your trailers holding tank from putting potential contaminates back into the city system. I shall have no holding tank so the check valve will be unnecessary in my case it would seem. I do want my inlet to be somewhat flush on the side of the trailer so it may be I need to get an RV inlet.

I am probably going to break down and buy one of these. It is just bothersome to buy something online for 10 bucks and pay about the same to ship it.

Closest one to me is 50+ miles away, otherwise I would be all over it.

I have a normal gravity flow. it has a little lid on the side of my trailer and I just pour the water in from a gallon milk jug it goes down my drain pipe hose to my 6 gallon black plastic abs tank which is mounted like a gas tank on a car underneath my teardrops frame and fastened with plumbers tape to my flour boards of my teardop.


all I do is pour in the water from a milk jug no need for even a funnel and no garden hose.

the only pressure on my styem is what I make at the sink in the galley which is a hand pumped manaul rv water pump or faucet.

slow.
Plans. there was supposed to be plans to be followed when I built this thing. Opps! AH, gee, tum,tee tum. I think I forgot about the plans 2 years ago. ------Tow vehicles, 1995 ford explore, 1994 ford ranger, 1993 ford F-150, 2009 4x9 Off road teardrop, on harbor freight greatly modified frame.

I do have a water inlet like bruce described on my teardrop but don't hook a garden hose on to add water!!!!!!!!!

you would get your water coming out the drain in my sink!!!!!

my city water rv water inlet is used for my drain to my p trap in my sink in my galley.

I hook a short peice of garden hose on it and stick the end of it in a wally world blue water tote jug and this becomes my gray water tank.

so my city water inlet is really the gray water drain on my teardrop.

I then dump the gray water from the sink in my blue wally world jug where ever I find a place.

it can offten be a badger or prairee dog hole or just plain tall sage brush.

...on our first tear, we used one similar to this ebay ckicky ...IIRC, the one we used was all polymer/plastic and was flush mounted along with having a barb fitting for 1.25"ID piping...when opened a standard water hose would fit right into it...we liked it....................
