Arrived on site and client stated when he would use the washer it would back up out of the tub. Upon further inspection in the crawlspace it looks like the washer ties into tub drain. Snaked tub and washer drain from crawlspace and it appears to be hair causing the clog. Ran water to test for leaks and ran tub and washing machine to test the drainage. Washer and tub are draining as they should.
