"I called All Appliance Repair and left voicemail regarding my 1 year old Bosch dishwasher that was refusing to pump out the old dishwasher water and producing an error code message of E24 Watertap. Steve called me back and suggested a couple of options I could try that were not in the Bosch dishwasher manual. His suggestions worked great and cleared out the clog in the air gap and our dishwasher is running again like a 1 year old Bosch dishwasher should! Thanks to Steve's customer service and excellent attitude we got it going with just a phone call free of charge."

Drain Cleaning FAQs, answered by experts

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

Clearing typically takes 1-2 hours, depending on the blockage size and location.

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.

Yes—your local septic company can clean your septic leach lines with a sewer jetter, a device that pumps high-pressure water through the lines to blast out any clogs and scum buildup. Unless there’s a clog or blockage in the lines, however, you do not need to perform this maintenance regularly. Do not attempt to clean your own leach lines, as you could easily damage them, leading to very costly repairs.

As a general rule of thumb, it’s best to clean your linear drain every two to three months to prevent debris buildup. However, if you notice it draining slowly or an odor from your drainpipes, it’s best to clear the clogged drain and maintain it more often. If you let a clog go for too long, you may have to invest in the price of professional shower drain cleaning, which costs about $225.
