I have a 8 year old whirlpool gas range that i want to replace with another brand new whirlpool gas range. I would like to know if I can just use the existing gas pipes/connectors and anti-tip brackets for the new one. Therefore, I would not need to bother with too much installation hassles. Just disconnect, pull out old range, re-connect new range, and push in. Is this possible?
Your gas connections are likely the same, 1/2" pipe with adapters to flare thread fittings for the flex connector. If there is any doubt about the integrity of the old flex, replace it. New ones come with the pipe thread adapters for each end.
Anti-tip brackets vary with the best ideas of the manufacturer at the time of design. If you stick with Whirlpool brand, it's possible (but not absolute) the new one could have the same type of bracket.
