If you are buying a universal kit that fits several toilet models, you should make sure that you are able to adjust the valves and bolts. This is the only way you can guarantee that your replacement parts will help fix your toilet.
Easy Installation:
You need to make sure that you are able to install the new part on your own. If you are in a hurry and need to save some cash, you are going to need a reliable kit that comes with easy instructions.
Hiring a professional plumber means that you are going to endure extra costs that you are typically trying to avoid.
