| Hey Alpac:
No problem on fittings. They are universal fit/type.
Pipes are different thickness...
TYPE M....Heat
TYPE L.....Water
TYPE K.....underground water.
You have type M in your home for water....a lot of homes built in the 70s have type M for water...not a really bad thing...just thinner, may break down sooner then the type L..but all in all...I see it quite a bit!!
So, anyway, fit up pipe/fittings as usual...just be careful not to overheat the type M...and solder as usual for type L pipe.
Good luck...Mark |
