Installing a hose bibb may seem like an easy, straightforward task. While it is true that anyone with basic DIY skills can replace one, it is essential to remember there are associated risks when trying to take on this job by yourself.
Without prior knowledge of the location, what needs to be done, or potential underlying issues, you can damage the structure or the existing plumbing system.
For this reason, while replacing a hose bibb on your own is possible, it is best to seek professional help from an experienced plumber who knows how to do it properly and safely.
