Under contract on a house 2400 sq ft. (4 full bath)(kitchen)(wet bar) and the inspection report indicates the plumbing is pex with Qpex fittings. Not thrilled with that. No obvious, visible signs of leaks. Two questions, (1) should I run for the hills. (2) Is there a rough estimate for that size home as far as changing out the fittings--I know this could vary quite a bit for various reasons, but we are negotiating repairs and it would be helpful to know about how much this would cost were we to continue with the purchase.
