"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

I highly recommend this company for anyone looking to enhance their outdoor space."
