Gravity Water Fill Cap

[jeremy]

Has anyone found a replacement for the tank water fill cap on a '76-'78? Not the city water, but the water tank filler that is behind the driver's
side door on the later models? The inlet is threaded so a Valera cap, while the correct size, won't work since it is not threaded. Otherwise anone got
a later model they are parting out I can have the fill cap from? Who knew this would be such a hard item to find?

I called Applied. According to them they don't have what I need so I'm assuming that is not a threaded cap.

Oh wow. I always figured if Jim K can't help, you are well and truly screwed....

Hmm, this sounds like a project for one of the 3d printer guys around? My 78 cap is working for now, but I cold se it getting brittle. I am willing to
take some measurements if any of the 3d guys want to try it.

I don't think this is a screw cap, either, but it looks like you might be
able to replace the whole assembly fairly easily. Sort of a last resort.

It's not and you might be able to. It is my last resort. However, the piece in my GMC you would need to remove is not round like the replacements.
It's kind of horseshoe shaped. So it isn't a simple swap for either this round one, or the square option. That's why I'm tring so hard to just find a
cap!

Just plumb a bypass valve from a tee in the city water line to a tee at the
outlet of the tank. That way you don't need the gravity fill -- just turn
the water pump off and open the bypass valve to fill the tank.

'Course that don't help them none who likes to use water buckets.

Ken can't that over power the tank overflow and "wet the rug"? I you don't pay attention

John,

Perhaps. In my case, no, because I converted the large (1"?) gravity feed
port to be the overflow. Stainless steel wool in that drain keeps the
critters out.

More recently, I converted the whole thing to electronic control: A $5 or
so board controls a $5 12VDC valve. When the H20 level drops below a pair
of well nuts (Common & Low), the valve's opened. When the H20 reaches the
Full well nut, the valve closes. No more laying down watching the level
rise in the translucent tank with a light behind it.

For those who don't want city water pressure inside the coach, this would
seem to be an ideal setup -- mount the valve immediately downstream of the
water inlet check valve so that there's always water in the tank but seldom
city water pressure inside. Manual switching can prevent unattended
filling, or can override the control to top off a partially full tank --
still under automatic full protection.

Man we are in mountain and mole hill territory. There is nothing wrong with my fill system. I just would like a cap that fits the existing inlet. It
looks like that is hard, if not impossible to find, so I may go without, counting on the door to keep the critters out, or I'll change it out with
some effort to a more common inlet. Just looking for simple first. A new cap would be great!

Just go to home depot and get a 1-1/4" pipe cap. It might not screw on
perfectly but it will stay on. At least on the one's I've seen.

Thermos bottle cork?? Either actual cork or the expanding lever kind.
Also measure OD of the neck and compare to various grocery drink
products, then compare threads. Possible Mickey mouse solutions.

Jeremy,

I just can't understand why anyone would want to use gravity feed -- unless
they're dry camping and want to fill from a mountain stream or something.
Otherwise, sticking a water hose into a gravity port seems to me sort of
"old fashioned" -- not the thing for our MODERN coaches.

Guess I should try to remember what it was like to be young, with kids and
a job occupy my time, tho', instead of needing a GMC to find things to do
to, huh?

Ken,

Apart from filling from a mountain stream (Which I have done), there is also the case of non-FHU cramp grounds that have a single hydrant that has a
hose with no threads anywhere in sight.

Then there is the fact that you don't know because you can fill unattended (which I think is great) and that is the admittance of a straight hose is
higher than working through the coach plumbing. Yes, I have and use the pump by-pass and think it is a good idea, but it is slow.

And finally, if one chooses to sanitize the system, it is easier to pour whatever (I use 20% H2O2) right into the tank.

Because it is there, it works, it's quick, and it's simple? There are a lot of things I can work on with my GMC. In this case inventing a solution to
a non-problem isn't high on the list. I like your idea Ken and I think you hit the nail on the head. If I was retired and had a lot of time to work on
my GMC AND use my GMC those are the kind of projects I'd probably play with. But I don't have that time. So I spend the time I have working on things
that need to be fixed or that I want improved (forever thankful for my macerator!) but I don't need to recreate the wheel when the round object I
already have rolls pretty well.

I will say we were recently at Lake Fairfax Park in VA just outside D.C. The sites had 50 amp, but no sewer or water. So when you had to fill or
dump, you had to go over to the dump station. The outlet for the fresh water had a hose that was rusted tight to the pump. Could I have gotten it off
with some time and tools? Probably. But I didn't have the time to do it since we needed to be on our way to a funeral. The other end of the hose had
no fitting. It wouldn't have been fun to fill without a gravity fill. Could have done it later that night when we got back by removing their hose and
using my own, but my kids would have been up really late and Mom wouldn't have been happy.

And yes, the condition of their hose made me not want to use it. But needs must and we simply didn't use the water for anything but flushing and
washing dishes, emptying the tank and refilling at our next stop.

This right here. How did I not think of this? Brilliant. Wish I didn't have 100 other things I needed to do today and could have tried this. Maybe
tomorrow. That's the idea I'm looking for! Thanks Billy.
