[Fulltiming]

It has been a number of years since I had mine apart but in looking over some parts lists, what I think I found was that rather than separate filter/strainers, that when I removed the thermoelement cartridge and the stop valves (small valve on each side of the center thermoelement cartridge) that they have holes in the rear of the valves and cartridges that were partially occluded with calcium deposits that were significantly reducing the water flow. At any rate, after removing the cover plate the cartridge and stop valves are visible and can be unscrewed to see if deposits have partially plugged the holes where the water enters the rear of the valves and cartridge.
