Ok here goes,
Today, a friggin cold water line to tub developed a crack, made a big mess. I had to use push-fittings to create connection so we can have water tonight and tomorrow morning.

My concern is how good are the push-connect fittings?
Are they good for long term use or temporary repair?

Do not sugar coated it, tell me the truth because it is the first time I've use and I got a weird feeling about it.

The link below is the type of fitting I use.
