I have a small leak in 1" PVC pipe at a connection to a shutoff valve. It looks like not enough PVC cement was used. Taking this apart to repair it will require the entire household water system to be shut off. I would like to replace the valve/pipe as quickly as possible. Is there a fast curing PVC cement that I can use on a potable water system? I would like the system to not be down more than a couple hours.
NOTE: The leak is actually at the connection of a PVC valve. It looks like there wasn't enough solvent/cement used.
UPDATE: There were a lot of great suggestions. I ended up following Ed Beal's answer for a permanent fix. The cure time chart on the cement said I only needed to wait 20 minutes before pressurizing the system again. Took me 30 minutes from start to finish (not including the wait time to turn the water back on). So far no leaks.
