CPVC tastes yucky

I come seeking the wisdom of the graybeards. I replaced all supply lines in a 1920's home recently. The client's budget dictated cpvc. Everything works great, but the kitchen water tastes like plastic. The kitchen sink was installed 2 weeks after I finished, so water sat in those lines that whole time. I flushed the lines for 20 minutes, but this AM the taste was still there. I used Flowguard Gold pipe. Is it possible glue solvents in the water migrated into the plastic and is now diffusing back into the water? Thanks.

That could be the cause and the amount of 'glue' used if more than the thin light coating called for. And it could be psychological because they see/saw all the plastic tubing and fittings or, because someone ask them if they have a taste or smell from the plastic. I don't know what the answer is but you could try a drinking water filter with a carbon block cartridge in it with a separate RO faucet.

You could try a chlorine flush of the system.

Thanks Gary and dcellite. I was leaning towards psychological because this hasn't happened before.Same brand pipe, cement, primer I've always used. Only thing different was the length of time before lines could be flushed out-and the client is different, too.

Hi,
