So do you think it is a gamble and I MAY drop the pressure a few PSI?
If the added pressure is known to be the result of head loss from the heater, would a guy just add the extra pressure to the standard of which you backwash/clean the filter? For example, since I use to backwash at 26 I now backwash at 35? Would that shorten the life of the pump? I ususlly just take the de filter apart and clean it instead of backwashing.
