Upon arrival to the home the homeowner made me aware that they had a leak underneath the kitchen sink. Upon further diagnosis I came to the conclusion that the cause of the leak was a old supply line extension that was leaking around the feral. I proceeded to replace the supply line extension to fix the leak. The customer also stated that the hall bathroom shower The waterlines or switched for hot and cold but they said that they can live with that until Monday. As a courtesy I crawled around under the crawlspace because the customer had asked me to and everything is working properly under the house and there are no leaks.
