TPR - pipe run...question

[David Nasser]

Is this acceptable? Or does it have to always be sloped downward.

[Jeffrey R. Jonas]

Always sloped downward so any water that may be beginning to leak (dripping) will flow with gravity, and not collect in the drain line.

See it all the time. Not acceptable...

I guess Robert's not the only one that doesn't like me.

I assumed it is visible, very common in CA., thus my not mentioning it.

Not allowed to run uphill and the corrugated flexible copper tubing is not allowed either.

Do you have a reference for that Charley? I don't like seeing these used as part of the TPR discharge, but I haven't seen anything that would prohibit their use.

You would think there should be an air gap just to see if it is dripping but since it is calif.....

Even in CA, this is an improper installation, so I don't understand your post.

To clarify, the termination will generally be on the exterior in this type of set up, so (based on my experience) I'm assuming it's visible. The uphill slope on the discharge is improper, but I'm not aware of any restriction on the type of material that has been used.

The TPR line inside diameter is not allowed to change/restrict the corrugated Copper line is rated at 3/4 inch yet is has a 5/8 inch diameter therefore restricting flow.

UPC 608.5. Not sure what the CPC cross reference number is but I bet it is the same
