"Selvin of Propipe plumbing was very courteous and got the cartridge to fix my leaky bathtub faucet. He fixed it right and charged a very reasonable amount. I had hired Varsity the year before and they charged twice as much, and the faucet still leaked after they left."

"The owner was personable and professional while doing the estimate. Afterwards when handing the cash he disrespectfully threw the envelope on my property in my yard as he was leaving knowing I was there. He did not want me to directly to tip the workers. Garbage was left underneath a panel of fence not used. The workers he hired did a great job and I ensured they received their tip from the thrown envelope"
