Has anyone upgraded the demand pump in their rv? Our Jayco 25RKS makes noise from the flex tubing rattling against the floor and walls. Do pulsation free pumps really work as advertised.
I used a 2 gal exp tank and made a tee with a 3/8" copper tubing stub for the inlet water that goes almost up to the bladder (on the run of the tee) and the outlet water comes from the branch. That way the pulses get deadened by the bladder and the outlet water is out of the immediate vicinity of the inlet flow. Mine used to hammer terribly and now I can barely hear it. Craig
