Make sure to turn off the water flow to the toilet before installing this. Get someone familiar with plumbing to install it if you're uncomfortable doing so. No instructions are provided, so it's assumed that you know what you're doing. Was install to install, though, so no issues there. Also make sure you have a proper wrench, otherwise you'll likely carve up the surface paint on the fittings. Looks nice, pressure is solid.

This sprayer is simple to install and has proven to be a nice addition for the bathroom. Has held up well and really helps make the cleaning process easier also. We'll worth the purchase.
