.     Aha!  Drat it!  The manual hopes that the system is above and not more than 20' from the drain.  Now he had the pex pipe run up to the ceiling!  Which is OK, but it can't go up more than 6 feet, which it doesn't, but then the run is only 15 feet and not less than 40psi water pressure.  It just makes 40psi as it is on a well, but then runs over 70 more feet.  (It can push for 2 more feet each additional 10psi.)

.     So I'm wondering about putting in a tank and pump right next to this?  So it pumps down 4 feet, then something else pumps it away.  What do you think?

.     So it is starting to look like the plumber's diagnosis is plausible, but the manual doesn't tell us WHY it wants it that way.  Is the reason for these specs the problem he sites or some other problem.

     Then, it also tells us an elevated drain line needs a 7" loop in it if the drain level ends up LOWER than where the drain tubing connects to the water softener.  That is, is the drain pipe from your washer higher or lower than the connection of the drain tubing to the control valve?  This prevents siphoning which is interesting that you have to avoid both backpressure from too long or high a drain and that siphoning is also undesirable?  Could siphoning be the problem here???

     Still considering setting a tank and pump on the floor of the basement  OR  running an 1-1/2 inch pipe over for the 3/4 inch pipe to spill into.
