6699 Tankless Water Heater Flushing Kit – 1/4 HP Submersible Pump, Hoses & Bucket Opener

Keep your tankless heater running at peak efficiency

The 6699 Tankless Water Heater Flushing Kit is an all-in-one solution designed to simplify routine maintenance without the guesswork. Centered on a compact 1/4 HP submersible sump pump, it quietly powers the flush and handles up to 1500 gallons per hour with a lift capacity up to 23 feet. The kit also includes two 6-foot PVC hoses with washers, two adapters to fit common isolation valves, a rugged 3-gallon bucket with a lid opener, and all the pieces you need to complete a flush. Note that vinegar or biodegradable cleaning agent is not included, so you can use your preferred cleaner with your own supplies. This setup aims to make the maintenance task straightforward, so you can plan regular flushes as part of your system’s care routine without tools or guessing dates.
