I recently installed a new dishwasher and afterwards - the kitchen sink hot and/or cold water continues to run for a couple of seconds after turning the handle off. The only thing I changed was going from a 5 foot small cooper tubing to a 7 foot larger diameter hose. Could the longer length and larger diameter in water supply cable be the result of the water running for a few more seconds after turning off? Thanks

Hey WDcollier:

Nope... larger/longer pipe should not make the difference.

Did you shut water off to the faucet? When shut water to disconnect the tubing for dishwasher did you need to shut water to both dishwasher and faucet (via 1 shutoff)?

Sounds like something got into faucet and has lodged under the cartridge or washer.

See if can find a name on the faucet... sounds like a single handle unit. See what we can tell you after that... ;)

Let me know all you can... Mark

I have 2 shut-offs. Prior to installation - I only shut off the hot water that was going to both the sink and the dishwasher. I didn't shut off the cold. You are correct - it is a single handle faucet by Delta. I still have good pressure although now when I press the handle down to shut off - water continues to release at a decreasing rate until after a couple seconds when the water finally stops

Does this faucet have a pull-out sprayer? If so, maybe you should check the following. The rubber hose between the faucet body and the sprayer can expand and fill with water when the faucet is turned on; then when the faucet is turned off, this water will slowly (relatively slowly, like in a couple of seconds) discharge through the sprayer. This would happen if the sprayer is constricted enough to cause this pressure build up to occur. Maybe a foreign object entered the faucet and is now lodged at the sprayer nozzle.

Brilliant! It was air in the sprayer line causing the delay (we don't use the sprayer,so that was a mystery.

Thank you!
