My wife and I had some pretty disappointing issues with drainage in the master bath, then I thought it was due to a jammed pipe in the shower, as occasionally hair can get into the drain line and cause major plumbing clogs.
I used a cheap plumbing snake to remove any hair or build up inside of the drain, but there wasn’t a lot of stuff that came out of the drain.
There was a little bit of hair, dirt, and pieces of soap yet it didn’t seem as if it was enough stuff to cause a major drainage problem. After a few days, all of us had drainage issues in other sites in the house and I noticed when the dishwasher backed up into the sink and it took a really long time for the washing machine to drain too. I decided it was a great idea to contact a plumbing supplier that specialized in drainage issues. I contacted the plumbing supplier and gave them some information about the issues all of us were having and the person on the line said it sounded as if tree branches might be causing issues in the drain line. When the plumbing supplier came out to check our home, the first thing they did was use a camera to check on the numerous parts of the plumbing located under the house. The camera was a great way to find the complication without digging up our entire yard. The camera showed a blockage 25 feet from our front door. The licensed plumbing business thought it was tree roots, so he dug up the section of the yard where the complication was supposed to be. And it did turn out to be a substantial root from the oak tree in the front yard that was causing all of our issues.
