my hus band is an excellent handyman but he cannot figure out why he changed the hot and cold knobs on our bathtub and now we have very very low water pressure out of the faucet. We have copper pipes.

Have hubby shut the water off to the faucet and remove the stem and washer assembles he just put in. Now turn the water back on to flush out the supplies. You should have a strong stream coming out. Now reassemble and test. If the pressure's not better then check to see if you were sold the correct parts. Regards, tom

That didn't work...any other ideas?

How strong was the stream when you flushed the supplies? Tom

Not much better than it was before

Did you have good pressure before he changed out the knobs? You say "knobs", that means he didn't open up the valve and change the stems. All he did was replace the handles? Is that correct? Why did he work on the valve in the first place? Give me all the details you can. regards. Tom
