"Western Rooter to the rescue again! I had a small underground leak which appeared to be due to a bad sprinkler valve. A sprinkler repair company determined that it was not a bad sprinkler valve and thought it was due to a leak in the main water line. Daniel and Alex dug down to find that the leak was coming from a very old (at least 36 years) broken pvc line. After much testing and head scratching to try to figure out where the water was coming from, they decided to "chase the pipe." After much digging, they found that the very old broken pvc pipe was hooked up to a sprinkler valve that was buried 18 inches underground that had not been capped--only turned off. Roots from a nearby tree had opened the valve which caused the leak--crazy! The current sprinkler system has been the same one since we moved into the house in 1988. It took 36 years for the underground leak to occur!"

Drain Pipe Installation questions, answered by experts

Anything you drop down your sink runs the risk of damaging and clogging your pipes. Hair, bits of food, and other debris can catch on the item and build up over time, causing a clog. Even if it’s not valuable, it’s definitely worth trying to retrieve the item, or at the very least, asking a pro for specific advice.

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

You’ll likely pay between $300 and $450 to unclog your toilet with Roto-Rooter. However, the price could change depending on if the clog has caused a lot of damage, which your plumbing pro will want to inspect during your service appointment. Keep in mind that you won’t get a quote from Roto-Rooter over the phone. They have to send a pro out for an in-person cost estimate. You can also attempt to snake your own clog for a lot less, and simple drain snakes cost no more than $50.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.

It is not advisable to use drain cleaner in a washing machine. Drain cleaners contain harsh chemicals that can damage the internal components of your washer, including rubber seals, hoses, and even the drum. These chemicals can also react with any residual detergent or fabric softener, potentially leading to noxious fumes. If your washing machine is experiencing drainage issues, it's best to address the problem directly by inspecting and cleaning the lint filter, checking for clogs in the drain hose, or seeking professional repair services. Using drain cleaner in a washing machine is a risky solution that can cause more harm than good.
