I am adept at plumbing with copper pipe. We're re-doing a bath and for the flexibility I'd like to use pex for a portion of the hot/cold water runs this time. I can borrow (no fee) a pex crimping tool from the local plumbing supplier but I think I want to buy a crimping tool for the convenience on this and future jobs. I see a tool in my store called Surlock. Is anyone familiar with this crimper and crimping system (which is different from the standard pex compression ring system)?
Another question: the copper lines that will feed my new pex runs are half inch. I notice that the so-called 'half inch' pex fittings (e.g., elbows) are really not half-inch inner diameter but _much_ smaller. Wouldn't using such a fitting simply mean I would not really have a half-inch line (but one much smaller)? If this is correct reasoning then I reckon I should use 3/4 inch pex line.
Thanks in advance, David Todtman
