This is not a lot of water per fill but if the water is relatively clean and requires no power to access - and is year round - this will suffice until I get my deeper manual "earthstraw" operational.
I ordered this brass foot valve - through the mail - why? Because it's the ONLY manufacturer I could find that gives the actual outer diameter for the valve! It's 1.22 inches!! The pipe is only 1.25 inches - so obviously this is the biggest valve I can get and as a foot valve it will screen out or filter out the water. Also the parts are just synthetic rubber and brass and stainless steel.
OK so now I tracked down a 1 inch PVC pipe and cap - and a brass adapter with a 1/2 inch male fitting - that works for potable water. So there's a 3/4 inch hex "bushing" on that adapter. So I can then drill a 1/2 inch hole into the end cap - and screw in the bushing - and attach the foot valve to the bushing adapter.
Then I attach the end cap with glue to the PVC - and hopefully the glue is not too toxic. I'll look into that. Also what is the OD of the cap? Probably bigger than 1 and 1/4" ? hmm. I might have to make the pipe out of something else?
so they will fit over 1" PVC pipe, which has an outside diameter of 1-5/16" (1.315").
Actual inside diameter (in.)1.38 of Well Pipe that is 1 and 1/4"
Wow looks like it might fit....?
Then the brass will give this pipe bucket the weight so it sinks into the water, thereby activating the valve as a one way release of water into the 1 inch tube.
The pipe is only 1 inch 1/4 for the well point. Actually there is a 2 inch well point so I could have a bigger "bucket" for that - but I don't want to deal with different size buckets - so I have to make it fit the smaller 1 inch and 1/4" pipe.
This is because any kind of pump would require too much power since I have an off-grid situation. So I need this smaller manual set up.
On the other hand - if it works - then I have year round water as a manual "hand carry" primitive situation with no actual well - it's a hole in the ground with no pump.
No rivets or anything! Looks like they [the Amish] just PRESSED a circular metal plate into the base of a crimped duct pipe....
