Michael Lynn Donalson
Owner
I hired Mr. Donalson after another plumber told me the way to fix my problem (a pipe burst underneath foundation) was to come to an outside faucet to attach new lines and then run all new lines inside the roof. Mr. Donalson is doing the job correct. He is boring underneath the foundation to bring the new copper line back to the old entrance of the water using 3/4 inch line. The first plumber was going to use a 1/2 inch pipe which would have constricted the flow of water into the house. I will always recommend someone who actually does the job right, not the one who wants the easy way to fix a problem. Mr. Donalson is the man!
