Upon arrival customer informed me that he had a leaking garbage disposal. There were washer and dryer installers there at the time. Customer supplied his own garbage disposal. I properly removed the disposal and replaced the strainer assembly. Customer disposal was then reinstalled and tested for leaks. Ran 3 drop test and no leaks. Customer also has a master bathroom tub valve that is leaking. The trim was the wrong trim for the valve. I advised customer my best recommendation to him would be to change the tub valve so that the trim matches the valve. Customer said he will go to Lowe’s and pick one out and call for me to install it.
