I need some expert opinions re gas piping. House is cast-iron from the street to furnaces and HW heaters.
We are remodelling the kitchen and plan to add a natural gas pipe to a new gas range (previous range was electric).
Plumber came out and gave estimate:
a. Cast-Iron piping
c. Flexible Stainless Steel piping.
a is mot expensive.
c is least expensive (in relative terms, if c is $1 then a is $3 in cost, b in between).
I am stuck with budget and need to ask people here:
- If Flexible is that good an inexpensive, why don't the rest of the world use it?
- I am used to cast-iron because I think cast-iron is the gold standard: solid and last along time. The down side is the cost.
I am heard somewhere that flexible natural gas piping has had some problems in the past.
Also I have a friend in Chicago suburb that says flexible gas piping is not allowed per code.
Any expert opinions out there re flexible gas piping?
