Whole-house water filter; Pressure question
Hello,
In my house, we have an AquaPure water filter on the main water line (right after the meter). It works pretty well; the problem is, once the new filter cartridge has been in for a couple of weeks (but not long enough to need a cartridge change), the water pressure begins to drop noticeably. So my question is: is there any way to boost the pressure past the filter? e.g. maybe I can install some sort of small tank right after the filter which would be filled with filtered water. When the faucet is turned on, the tank would supply the water full blast; meanwhile, the slow-moving water exiting the filter would replenish this tank in it's own good time (i.e. there's no rush; it can continue to fill even once I've turned the faucet back off).
In a nutshell, my idea is sort of like how water heaters work: since the user wants hot water immediately upon opening the faucet (and doesn't want to wait for the water to be cooked from scratch), a tank in the basement holds a certain amount of hot water which is immediately available; then, once the water has been supplied to the user, the water heater can heat more cold water at its convenience (so to speak) and "catch up" without keeping the user waiting. So too, with my idea: since the bottleneck is the filter, perhaps some [pressurized] water could be stored on the other side of the filter for immediate use, and then later, the filter can "catch up" without me being inconveniced.
Does anyone know how to make this work?
