Well Priming

Angle grinder with a concrete blade!

The pump is called a jet pump. Motor sits on top and pumps water through a bottom hole educator to suck up well water. All kinds around.

The well pushes water down an inner sleeve to get water up an outer sleeve (it may be the reverse of that as it has been 15 years since my brother and I replaced the pump and manifold and my memory is fading).

Wow, I knew this was possible but, it's so inefficient, I didn't think anyone actually did it.

It's, of course, very easy for us to spend your money for you but, you may want to have a real hard look at getting appropriate access for someone to come in and set a submersible pump for you. I'm certain you'd be a lot happier with it all the way around if you could do it cost effectively.

That is a jet or injector pump. Somewhat common around here, especially in the older houses. Water is pumped down forced through a venturi and sped up. Creates suction in well and is pushed back up. Like said above submersibles are more efficient and require less maintenance especially if water is sandy or silty as I have seen the venturi plug on them. Looking at your pics it may be difficult to drop a submersible down due to space. You could always run a hard line out for priming if you wanted.

"ejector" pump

Edit: and if it was me, I'd have opened up that access hole by now. Angle grinder!

I wouldn't have used used a conduilt or flex conduit. I would have used a cord or just hard wired romex.

I don't think you have a 125' deep well. If the pump is at the surface you have no more the 26 feet if one pipe going down or 52 feet if two pipes going down.

Maybe there are ways to do it, but you can only lift water so far. Deep wells have the pump down in the well, and push it up. You don't have to worry as much about freezing, when the pump is the water.


I'd make a bigger door.

I had a jt pump when I was younger, but didn't know much about wells then.

It is creating suction like a 2 pipe system, but can over come 26'?

Shallow wells can only "suck" from ~28 ft, but deep well jet pumps can pull up water from as deep as 150'.

Eric, you should examine whether you can install a submersible pump and a pitless adapter on the well. With the pitless adapter you can extend the casing up above the surface and do away with the well pit. The pipe from the pump will still come through the wall but you won't have to deal with a tiny room anymore.

The well depth is second hand from my father, and we have two wells on the property. The well i'm talking about may very well not be the 125' deep well, but the 80' deep well.

The last time the well pump shelled back in 2003 all we had at our local Fleet store, (which is where all of this came from) for "deep well" pumps where these jet pumps. The last time the pump took a dump, I had to swap out the manifold and the pump (GE 5KC39MN3918X) and the inner pipe dropped when the manifold was removed. My brother and I used a barn jack, muffler clamps and another section of pipe to "retrieve" the dropped inner pipe and attach the new manifold.

In his system the jet assembly is inside the piping down in the well instead of on the back of the pump as in a shallow well system.
The pump uses the impeller to push water down into the jet system which lowers velocity and raises pressure thus forcing water up. You'll lose prime the same way as in a shallow well.

He should really get a submersible or just add a filler nozzle to prime. And bust out that hole in the wall.

Yep, it another example of not thinking about maintenance when installing a system. Everything should be easily accessible. Well pits are....well...the pits! In most cases what is installed in the pit should have, and can be installed in the house basement if there is one or a service room on the first floor.

My neighbor had a new well drilled, house with basement, did he install the pressure tank and associated switches, etc. in the basement? Oh no, he installed it in a room in an outbuilding dthat was next to the well. and then found out he could spend a lot more money insulating that room to keep things from freezing up.
