Drain Cleaning questions, answered by experts

Clogs in a sprinkler valve can be caused by various factors, including debris in the water supply, sediment buildup inside the valve, or damage to the diaphragm. Debris and sediment can accumulate over time, obstructing the valve's passages and impeding water flow. Damaged diaphragms may develop tears or holes, leading to blockages and affecting the valve's ability to open or close properly. Regular maintenance and cleaning can help prevent and address these issues, ensuring your sprinkler valve operates smoothly.

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.

Clean regularly with non-abrasive cleaners, avoid pouring grease down the drain, and check for leaks under the sink.
