6699 SUB1100KIT02 Tankless Water Heater Flushing Kit with 1/6 HP Pump

The 3-gallon pail gives this tankless water heater flushing kit a defined capacity for a maintenance setup. It comes with a 1/6 HP pump, two 6-foot hoses, adapters, washers, and a lid opener. The cleaning agent or vinegar used for flushing is not included. The kit is designed to connect to tankless heater isolation valves.

Quick overview

This is an all-in-one kit for flushing a tankless water heater, rather than a pump sold on its own. Its submersible pump is rated at 1,100 GPH, and the package includes two PVC hoses and the fittings needed to assemble the setup. The pail, lid opener, and washers are also included, so buyers can source fewer separate pieces than they would when building a kit from individual parts.

The listed cleaning process uses one gallon of vinegar or biodegradable cleaner mixed with one gallon of water, neither cleaning solution is included. That matters when planning the job: the kit supplies the equipment, but not the consumable. The pump is corded electric and rated at 115 volts, with a 10-foot power cable stated in the product details.

Fit and sizing

The pail measures 9.8 inches long by 9.8 inches wide by 11.4 inches high. Each included hose is 6 feet long and 1/2 inch in diameter. Those details help establish whether the kit suits the space around the heater and the distance between the unit and the pail. Its pump is listed with a maximum fluid temperature of 95°F, so it is intended for the specified flushing task, not for handling hotter liquid.

The product information describes the pump’s maximum lifting height as both 16 feet and 16.5 feet in different specifications. Treat that figure cautiously when your setup depends on a precise lift, the listing does not present one consistent value. Also check that your heater has isolation valves for the supplied hose connection, as described for this kit.

Best use cases

This kit is aimed at routine flushing of tankless water heaters. For example, a homeowner carrying out scheduled maintenance can connect the hoses to the heater’s isolation valves, place the pump in the pail with the cleaning mixture, and use the included fittings and washers for the setup. Follow the heater manufacturer’s maintenance directions for the specific flushing procedure.

Buyer feedback commonly highlights straightforward setup, the kit’s included components, and quiet pump operation. Some buyers also report mixed durability, including accounts of the pump cracking after a few uses and a bucket arriving damaged. These are reported experiences rather than a guaranteed outcome, but they are worth weighing if long-term durability is your main concern.

Worth considering if you want the pump, hoses, pail, and basic fittings in one package instead of sourcing them separately. It’s not for you if you need the cleaning liquid included or if your setup requires a reliably specified lifting height beyond the conflicting figures in the product details.

Should you buy it?

The SUB1100KIT02 makes the most sense for someone who already has a tankless heater with isolation valves and wants a dedicated set of flushing equipment. Compared with buying a pump alone, the included hoses, adapters, washers, and pail reduce the number of components to assemble from scratch. That convenience is the central reason to choose this kit, buyers seeking a pump for broader jobs should compare its 95°F fluid-temperature limit and heater-specific fittings with the requirements of those tasks. The cleaning solution remains a separate purchase, and the mixed durability feedback makes this a less certain pick for buyers who prioritize a track record of long-term use.
