We had recently installed a new hose Bibb for the client, we arrived today because one of the joints under the sink are leaking. After a through evaluation of the system, I discovered that one of the solder joints had a slight drip coming from it. After speaking to the technician on site, they advised me, along with the client, after the install, the gate valve under the sink was turned and hard to reach. The tech then advised me they cut the pipe and rotated the connection. My theory behind the leak is that when they had rotated it, the motion had split the solder joint. I heated up the coupling, added flux and more solder to the coupling and there are no more leaks at this time. I advised to the client that there is no warranty for today, and that if it does leak again I will need to replace the valve for the hose bib and also advised them to have me remove the sharkbite fittings, at an additional cost. Will leave a revised quote for that service if needed.
