OK

I found the pump. It is a Shurflo Supreme Sensor 5.7.

When under flow from.....the shower.....for example. the pump clicks on and off. The flow surges and slows. There is never a time that a full flow is maintained.

I think that I remember reading that the pump is supposed to be variable speed up to maximum and continue at maximum when pressure is required. My pump does not do this.

I also read that the pump is to have an output of 5.7 gpm at 40#. Although I cannot measure this, I do not think that is being maintained. The piping looks to not have kinks and/or other restrictions.

Unless the world can provide additional places to look or options, a call to the factory on Tuesday is next.
