I have an ART. 906242 FP4AL007 Kitchen Faucet that has half the water flow rate of my two other WR faucets. I've replaced the quick connect per troubleshooting, and that did not work. The hot water turn off had the faucet washer missing. I suspect it disintegrated and was sucked into the supply hose. How do I flush the system?
I'm guessing ...but... take it off ..take it to the outside faucet or water hose hold the hose end tight on the faucet outlet and turn it on to back flush it what went in should come out .. but have you checked the screen on the spicket (where the water comes out) that usually unscrews an you will see a screen inside there that can get clogged in addition to several plastic aerator bits that can get clogged and this is a LOT easier than removing the faucet and back flushing it ..
Thank you wjha. I had already checked the two screens on the spray head. I will try your back flushing that you suggest to see what comes out. If nothing appears, I will use compressed air on the outlet hose. Both the hot and cold water are affected which may indicate that I need to dismantle down to the ceramic disc cartridge to see if something is trapped there.
I did as you suggested wjha. When I disconnected the quick connector from the outlet hose, I noticed an almost complete blockage of calcium buildup. I scraped it away. I back flushed all hoses with compressed air. There was no further debris. The calcium buildup was the problem which also explained why both the hot and cold were affected.

If you suspect that debris from a missing faucet washer has entered the supply hose, you can try flushing the system to remove it. Here are some steps you can take:
If the water flow is still low after flushing the system, there may be an issue with the faucet's aerator or valve. These parts can become clogged with minerals or debris, which can restrict the water flow. You can remove the aerator and clean it or replace it if it is damaged. If the problem persists, it may be best to contact the manufacturer for assistance or have a plumber to inspect and fix the problem.
