Thanks for the pictures and drawings. I see your problem. No you can't put the pump up at the house, as a shallow well jet pump can lift a max of about 24' at sea level. You will need to push the water up, not suck it up. The 30' of elevation and the 20' to the top of the house add 50' or 20 PSI to the total head. That pump is probably working with a 30/50 pressure switch, which means you are seeing between 10 and 30 PSI on the top floor. I don't think I could run around in the shower fast enough to get wet. Lol!
You can put a submersible in the lake and have as much pressure as you want. Or you can replace that pump with one that has a max pressure of 80 PSI, like the J15S I recommended. You could set the pressure switch to 50/70, which would give you 30 to 50 on the top floor. Adding a Cycle Stop Valve would give you a constant 40 PSI on the top floor, which is 400% stronger pressure than you have now.
Another option is a multi-stage booster pump like a Goulds 10GB10, 1HP. These pumps are basically just a multi-stage submersible pump end with a jet pump type motor. As with a submersible out in the pond, you can have as much pressure as you want. The 10GB10 would work with a pressure switch setting of 80/100, which would give you 60/80 at the house and a constant 70 using the CSV1A. With 70 PSI constant in the shower you will not even need to ever clean the grout again.
I have done systems like this up to 400 PSI, when the house is on top of a 800' tall mountain. This is why I always complain about people complaining they don't have good pressure like in a city. It is your water system. You can have as much pressure as you want. Just need enough of a pump to make it happen.
Ok great, and thanks. I ordered the recommended 1.5 hp goulds pump and the cvs kit which will be at house level. I had them preset it to 50/70 and they said it would be great but I would just have to bypass the pumps pressure guage settings.
You've been a huuuge help and saved us a lot of money. Looks like a great setup!
