Flip Your Flapper

Did you know that every five years, you should replace your toilet flapper — the rubber device inside the toilet tank that holds water in the tank, then releases water into the bowl when you flush? Once a flapper wears out, you could be wasting water and money on your water and sewer bill! It’s easy and inexpensive to replace it, so flip that flapper at least every five years!

Pro tip: Before you buy a new flapper, take a photo inside your tank to make sure you buy the right one.

Don’t Flush Wipes or Pour Oil/Grease into Drains

With hand hygiene at the top of everyone’s minds and toilet paper in high demand, many households are increasing their use of sanitizing wipes and “flushable” wipes. Please do not flush wipes down the toilet. Flushing wipes, paper towels, or other paper products not intended for use in wastewater systems down the toilet can lead to sewer backups and in-home plumbing issues which may be expensive to repair. Even wipes labeled as “flushable” or “biodegradable” can cause backups for sewer utilities and headaches for homeowners.

Kitchen fats, oils, and grease (FOG) are a special category of harmful waste that clogs our pipes and causes serious
problems. Please do not pour any cooking oils or grease into your kitchen sink, bathroom sink, toilet or any other household or outdoor drain. As grease cools, it solidifies in sewer system pipes and pump stations. Blockage can lead to property damage, damage to the sewer system, and public health hazards from sewer backups and sewage overflows.
