PEX with Wirsbo fittings?

[Trent Tarter]

This place has some new PEX pipe with Wirsbo fittings. I talked with some local plumbing suppliers, some say it's ok, some say manufactures won't warranty there product with other manufactures fittings.

I would say Keep them visible and keep an eye out for drips. Have a plumber check the connectors, maybe if you see any reason to suspect them.

If you could name the contractor who did the work, you could give that info to your client.

It could be a reputable outfit that did the work, and they will stand behind their work, stuff like that.
