If I understand your question correctly your pump is starting and stopping rapidly you need to tighten down the pressure switch under the Black cover

The pressure tank is Water Worker HT20, so 20 gals. I would say it takes about 10-20 secs to get the pressure in the system from 20 psi to 50 psi. Since what makes it come on is an open faucet, there's usually a drain while it's pumping up the tank. I have no idea whether 23GPM is accurate, but it's plenty to do laundry and shower at the same time.

It came with the pump when I bought it on Amazon. Maybe they change them from time to time.

It stops on its own when it reaches 50psi or so. The pressure tank psi needs to be 28. Their service support is actually very helpful and helped me figure out the setup.

The switch has a power cord coming out of it, which I just plugged into the wall socket. I had to change it from 220v to 110v. It's in the instructions, which I didn't fully read, and the tech support had to tell me to do it.

@@VuduOJ the black box is a pressure switch. If you dont have one like me and you want to run off a 110 switch. Look inside the plate and hook up L1 and L2 as your hot and neutral. That was the answer to al my problems

I had an Everbilt before, which broke down (they have a pretty bad reputation). Red Lion is a little bit quieter, but it feels more powerful. Sort of like the difference between standing next to a loud Honda Civic without a muffler vs. a Mustang. Both are loud, but differently so. Maybe the difference isn't that dramatic, but noticeable.
