checkvalve location

[45Frank]

I just purchased property with a sub-well, it's 208 feet deep, I noticed that most of the piping is gone. The well works because I've had it running. My question is I noticed no checkvalve for one. The other is the expansion tank is right above the ground and the house will be about 275' away do I need enother tank or check valve.

You have a deepwell and it will have a foot valve at the bottom of it. The tank is fine where it is. You don't need another check valve or tank.
Here are a couple of excellent tutorials on wells-and-pumps that should help you understand your system.

Good luck!

With a submrsible pump you only have one line up the well from the outlet of the pump and underground usually through a pitless adapter through the side of the casing on to the house. You also have a power cable, but that's all there is.

Gary, -
"You also have a power cable, but that's all there is."
I was taught to always add a safety rope to the pump, good practice, as I've seen a few pumps break both tube and wire and fall to the bottom. Don't you use safety rope back east, or did you just forget to mention it
(just curious)

Few wells here have a rope and I don't use them unless the owner insists and quite strongly. I've had a few that when I went to pull the pump were broken and that can cause some serious problems in our rock wells in some cases. Here we use pump pulling machines set on/over the casing and rope gets in the way more than providing any benefit. We usually hang our pumps with brass or now SS males on 160 or 200 psi rated PE tubing to 500' and don't have pumps falling off. Although I had one last year hanging on a narrow thread of a cracked nylon male adapter; no rope. I don't know who would have installed a nylon fitting but they did. I found the pump running constantly while replacing a softener. You guys use derrick trucks or pulling machines?

For the common subs 1/2 -1.5 hp , we use electric pulling machines that wind the rope, or in many cases (too many) pull by hand. The rope of choice is 3/8 fullbodied yellow poly. Break strength about 450 lbs. I've never known one of these ropes break. In domestic and small farm wells here most of the pumps are hung on 1" or 1.25" id. pumpdrop. This is a black polyplastic, quite flexible, comes in rolls of 300' and 600'. A new coiled roll is about 4 feet in diameter, gives you an idea how flexible it is. It's easily cut by hand shears.
There are still a few subs hung on Sch 40 or other rigid plastic pipe, but not many. Anything bigger than 2 hp is usually on steel 1" .
Most domestic wells deeper than 60' around here are drilled with a 6" steel tube. :cool:

Same here for everything but the rope, all I've seen here is 1/4 or 5/16" blue and white poly, and the drum type puller I guess you use. I looked at a drum type from Hydrofrac in Mass or somewhere in New England and one from out your way in Canada but opted for a Pul-A-Pump from NJ. That's the one with the pair of tracks to grip the drop pipe if you've seen any pictures of pulling machines. We can't get a truck to most wells here that are on property more than maybe 30 years old and there's a lot of them. Our PE comes in 100, 200, 300 and 500' rolls.
