Hello Randy V,
Thank you for your question. We would recommend flushing the hot water supply line. To do this, gather an adjustable wrench, some towels and a bucket.
Shut off both water supplies.
Disconnect the hot side Innoflex line and point it into a bucket.
Move the handle to the full on position, middle temperature.
Turn on the cold supply valve full.
Let a gallon or two flow into the bucket.
Shut off cold water supply.
Check bucket for debris. If no debris, empty bucket and run one more time.
Move the faucet handle handle to off position.
Reattach the hot side line.
To flush the cold side Innoflex line, just substitute cold for hot, and hot for cold in the steps.
