Is it safe to use chemical drain cleaners? The answer depends on a few factors. First of all, you should understand that Texas does not regulate the use of chemicals on septic systems. The only way to be sure that you are using the right chemical washer is to call your local health department.
If you use a good brand of chemical drain cleaners, you should have no family safety problems. Keep in mind that you should never use anything that has ammonia in it. Ammonia can be hazardous. You should also be careful that the chemical you are using is the correct one for your system. Even if you read on the bottle for a certain kind of drain system, it may still be dangerous to use the wrong chemical.
