I've done plenty of work with PEX pipe over the past couple of years. I am now getting into renovating homes and some have to be fully gutted. My question is from simple a cost savings/quality stand point are the plastic fittings just as good as the brass ones? I will be purchasing these in large quantities so small savings like this adds up, and the fact the even at HD or lowes they are half the price of the brass make appealing to use. I just don't want to use them and the person who purchases the home have a problem shortly after purchase. If they are just as good then I'll most likely use them. But if anyone has had experience with them and the quality just isn't there then the savings won't be worth it.
