GLASS RINSER INSTALLATION
Some companies say that you can install a glass rinser yourself relatively quickly because they replace sprayers, soap dispensers, or sink hole covers (for instance, if you have a four-hole sink but your setup doesn't use all four of them, you'll have caps on the unused holes).
If you have an under-the-counter sink, you can install it on a countertop hole by yourself, assuming you have an existing spot on which to put it.
