We get a "knocking" in the lines every time we turn it on now. It's been a couple weeks and it hasn't gone away. Any ideas what's causing it and how I get rid of it?

Maybe you need to take the fawcett off and put on a faucet? :nodlaugh:

On a serious note maybe if you lessen the flow at the cut off valves it would return the flow rate of the current faucet back to that of the old one. Could be an increase in flow rate that is causing your issues. How to fix that besides trimming back the flow rate I don't know.

It might be a loose seat in the new faucet.

I could be coming from the angle stop under the sink. If the are not on all the way they can rattle. Check that first. Maybe turn the handle a little also to see if it stops. Just make sure the dont leak after.

Of course every application is different.

You need to install "bumpers" if they are not in your line. It's pretty much a couple of offshoots that are capped. There is air in your lines and it is almost impossible to get rid of.

I think it has been said, but...

1st.....Check the "O" rings on the new faucet, more that likely that will be the problem.

2nd....Drain you lines and re-pressureize them, this will push the air out. Keep in mind this doesn't always work.

3rd...."bumpers" can work, but you need access to your main line for the to work correctly

4th....and most likely the least probable. You have had an increase in pressure from the main. If you have a flow regulator, it could have gone bad, especially if you live in an area with hard water and the house is 15 years or so or older.

All of this is good info, But if it were me, CALL the PLUMBER !!!!! (I'm one of those Tim The Toolman Taylors) If it will leak,break, or anything it happens to me , So I'm $$ ahead by calling the Pro's to start with .... Good Luck Wade
