Thread: Self Piercing Saddle Valves, Acceptable or Hack?

Never been particularly happy with self piercing saddle valves but there are pretty common place for refrigerator ice makers, humidifers, and similar appliances.

Are they code approved? If not, does anyone a reference that states they are contra-indicated?

As far as I know they are about as "code" approved as a flexible drain line on a kitchen or bathroom sink!

Well the code at least states plumbing pipe must be smooth wall so actually contra-indicates corrugated flex pipe.

I don't remember seeing anywhere that self piercing, self tapping valves are not allowed. Might be there, just can find it. Hoping someone could point to a specific reference. I can say I don't like them but that is not enough for me. I want an authoritive reference to confirm my dislike.

In the 2012 North Carolina Plumbing Code which is based on the 2009 Int'l Code, Section P605.9(4) lists "saddle-type fittings" as one of the prohibited joints and connections.

I've been out of town for a few days so was unable to reply.

In my opinion these things are junk. In my area they are used a lot to supply water to evaporative coolers. They have to be turned off and water drained from the supply line every fall. I can tell you that a large per cent of them fail. They are fine as long as you don't operate them. I had heard that they were not allowed in some areas and I agree that they should not be allowed. They are the lazy way out. Have a qualified plumber install a proper brass ball shut off valve. JMO!!
