DO NOT HIRE!
He doesn't hold a license.
He has 0 knowledge of plumbing, had a major leak first use of a bathroom tub, the professional plumber i hired to assess the situation was shocked: he used gas connections instead of plumbing connections, and damaged 1/4 of the house walls and ceilings.
Also tile work was a mess.
He will tell you stories to take payment upfront. and won't complete the job.
I paid for 3 bathrooms and only 2 were done, had to stop him after trying the 2 first and realizing that he doesn't know a bit about plumbing.
