We had troubles with replacement of an old faucet for a Roman tub due to the cramped work area beneath the faucet. They began with service over the phone and sharing pictures so that they were able to determine some of the possible problems and determine a way forward. Once on-site, they were able to make the replacement fixture fit into the space. They were able to troubleshoot and resolve issues, such as proprietary connectors in the piping. The new installation works like a charm and would recommend.
