Installation Ease

I found it helpful to think about the ease of installation. Some fittings come with additional features that make installation simpler, such as built-in O-rings or easy-to-grip designs. I appreciated products that provided clear instructions, as I planned to do the installation myself.

Brand Reputation and Reviews
