Pump Replacement - Jet Pump or pay for Submersible change over

Hello,

Currently (see picture) I am running a very old double-pipe jet pump system. It runs on 120v with a 3/4 hp pump which makes me guess my well is not that deep. The house was built in 1964 so the well is probably that age. I have only been in the house 2 years so I don't know any other details. The bearings are starting to go on my jet pump and for the 80$ I called a well company out to get their opinion on the situation. They strongly advised that I convert my pump to a submersible for many benefits. The told me that since I had galvanized steel running to my well as seen in the photo next to my pump that it is only a matter of time before it rusts and starts to leak. Currently the pump has no problem holding pressure with 0 leaks. They also said my foot valve will most likely go making even a brand new jet pump not work. To fix this issue they will run electrical thru the 1" inch line to the well and put 1" plastic line for water through the 1-1/4 pipe to the well so I don't have to worry about leaks. This all sounds good but what worries me is that they don't know where my well is in the front yard and I think they are expecting to just dig a find a well with a plastic cover they could just open. My neighbor said are wells are surrounded by brick and concrete top which I can just see the cost going up with. Now I can install the Jet Pump and Tank myself which would save me alot of money with the help of best friend who is a plumber for free but he wants nothing to know about the conversion since he doesn't work on wells. So the questions is:

1. Do I order a jet pump? Which model is your favorite for my application? What do you really think the chances of the pipes leaking or the foot valve breaking in the next 5-10 years are? I figure even if it does break all I lost is the price of the pump since the pressure tank will be reused and I will just have to go the submersible route at that point. I figure this route will cost me under 800 with labor free. Also, Electricity is not a issue to me since I work for the provider and get very cheap rates.

2. Do I pay the company to do the conversion? I know it will be better for the long run but the quote is for 2900k and I got a feeling its going to get more once the get in there. They also want extra to put a attachment to bring the well head above ground for easy service.

Would I be making a huge mistake if I just put a new jet pump on?

If you made it this far thanks for reading

Lou

2900k for installation ?

There are a lot of unknowns here...... age of point, depth of point, age and condition of pipe.

I'm not an authority on two line jet pump systems but normally the point is sized to the pump.
In the following diagrams...... both are two lines from the pump but different applications underground.

I would just replace the pump...

If you add a submersible to a shallow well you will probably just over pump it...

And if the ft valve ever goes or the ejector then you simply pull the line and replace it as in the pics pete shows...

yeah to your point in the picture I have no idea what is going on underground. I think right now I am going to stick with replacing the current pump I have. One last question. Would it matter if I upgraded to a 1 hp instead of a 3/4 hp pump?

why upgrade? A 1 hp pump will run more GPM... Is the 3/4 not good enough for the demand? Again you may over run a shallow well...But we don't know your wells capability's...
