My 1/2 hp jet pump starts/stops several times in rapid succession after I recently moved the red lion RL20 20 gal pre-charged pressure tank. This is a cottage application where the jet pump draws water from the lake. Prior to moving the pressure tank, the tank and the pump were about 80' from the lake with vertical height of about 8' and only a few feet from each other. There is a 1" poly pipe from the lake to the pump. Everything was working well before moving the pressure tank.
I moved the tank as the first and temporary step in installing a winter water system. The pump remained at 80' and the tank now sits at 116' and about another 5 feet higher. In addition, there is now a check valve between and near the tank and the pump. The foot valve remains in the lake. I know its weird to have a check valve here but as I say its a temporary step until I get a submersible pump installed in a few weeks. There is 1/2" poly between the pump and the pressure tank. As I say, after I made this change the pump goes on/off in rapid succession several times them stops. I am getting pressure but it at the low end. If I run water it does it all over again.
The research I've done tells me that my problem could be the now larger distance between the pump and tank. However, I've also moved the tank higher. I'm trying to avoid getting a larger pressure tank because its hard to accommodate its larger size. Will moving the jet pump to 116' with the tank solve the issue, or do I need a new pressure tank? Would an undersized pressure tank by this margin cause this?
Any thoughts as to what could be the problem here?
