I just replaced my old pressure tank.
Both switches were set to 30/50 psi.
On the old one, there was a little manual lever that you had to use anytime the pressure dropped below 20 where the switch would turn off completely.
This was useful on the off chance that the pipes froze, which they did once when the heat tape around the pipe buried 6ft below the ground froze on a very cold week.
The PSI drops to 0, and the switch doesn't power the pump any more until someone pushes the lever to manually provide power to the pump until it gets > 20 psi at which point the switch takes over.
On the current new switch, it just powers on automatically even when PSI is at zero like it is when the tank is empty and you want to fill it.
Isn't this dangerous for the pump?
If the line freezes again, water will not get through to the tank and the switch will constantly power the pump to try and get water therefore burning out the well pump.
Edit:
Some more questions
1. Is it ok to use those plastic connectors with barbs and threads into the T pipe? That's also what the hardware store gave me but I've since read about PVC connectors cracking. This is only holding cold water.
2. Can I buy a 20/40 with low pressure and adjust it up to 35/50? The only ones with switch here are 20/40
3. The pressure tank is creaking when it gets up to 55PSI - is that normal? Air preset is at 28PSI.
4. Lastly ( ) - the horizontal pipe where it joins the 90 degree elbow before going into the tank is leaking a bit. The hardware store guy tightened this for me with a wrench but maybe he didn't add enough wraps of PTFE? Just guessing. I don't think I would be able to tighten this more especially not 1 full turn to get it all facing the right way again. Will I have to disconnect all of it now?
