    If you’re looking for a reliable, licensed plumbing company for septic tank replacement, Diamond House is it. My septic system failed that caused my house to start backing up, and they did everything from start to finish. Joshua was professional, knowledgeable, and helpful throughout the entire process. He guided me through the city permits and septic inspections which can be a huge headache, and made sure everything was done correctly and up to code. What really impressed me was their attention to detail.

    The said they camera’d from the inside toilet to the septic tank. Don’t know how they could have done that when the next plumber found it plugged at the baffle t. They said they would be available all weekend. They weren’t. It took 4 days from the time we paid them $1300 to get a written report even though that entire time our drain was clogged so we couldn’t use our toilets. We asked him to refund part of the bill since we had to spend so much having it done correctly and he refused.

    Response from the owner

Around Riverside, the main drain-field limit is slow water movement: water leaves the soil too slowly for a conventional field to keep up. Site conditions on any one lot can differ from the map. See the Riverside city page for the full soil profile.
