Re: Older hospital grade vs. new PIS
Most Pump in Style pumps, especially the older ones, are made to be used for about 6mos (pumping 3x/day) before the motor wears out. So, your low output could be a direct result of the pump being old. Miniscule cracks can also appear in the plastic parts, lowering the suction.
You may find much better results by either buying a new pump or renting one.
