I recently had a new Moen 275 vertical spa shower installed. The shower is basically 5'x5' and the ceiling height is a little over 9.5'. Two body sprays are installed on one wall and the other two sprays are on the opposite wall. Both sets of sprays have a balancing loop and are connected together through the attic.
The water flow goes like this:
Hot and cold mix at the mixing valve.
mixed water goes to diverter
from the diverter the water goes to the top of the shower then is tee'd
each leg of the Tee feeds one of the balancing loops.
Here's the problem. When the diverter is closed, the body sprays remain on for over a minute. One of the sprays has water shooting 3-4 feet for about 45 seconds. I know that this is due to the pipes draining but don't know how to fix the problem.
The builder's plumber said that it is normal for the sprays to drain for up to 30 seconds (per manufacturer's literature). I have to question whether this covers a 4 foot stream.
Of course because the pipes are empty the sprays spit and spudder for some time after the water is turned on.
Is there any way to remedy this problem short of repiping the shower?
