Full listing title: Safetech Tankless Water Heater Flushing Kit with 5-Gallon Screw-Top Lid, Premium Hoses, 1/6 HP Utility Pump, 4 Quarts Descaler, and Pump Grate
Rated from the listing's specs, no buyer reviews yet
What it's made for: skipping the service call for a job that takes an hour.
Two flush kits close to it on our rating, each with a dated price.
The pump the listing states. It pushes the solution through the heat exchanger and back into the pail for about an hour; the hoses have to reach from the service valves down to the bucket.
What it has going for it
5-gallon pail. The bucket the solution circulates through. A lid keeps the splashes off the garage floor.
Yourself: the kit gives you a 1/6 HP pump and a 5-gallon pail, per the listing. With service valves on the heater, it's an hour with a bucket on the garage floor.
Book the plumber: if your heater has no service valves yet, the first visit is to put them in. After that, this kit does the yearly job.
The seller states, word for word, in the Safetech Flushing Kit (5-Gallon Lid) listing:
Pump grate keeps debris out of the system for smooth flushing.
Eco-friendly descaler dissolves limescale effectively to restore water heater performance.
The seller's words, quoted as written; we haven't checked them. Your heater's manual decides whether it fits.

Our take
Our favourite thing about the Safetech Flushing Kit (5-Gallon Lid) is a 1/6 HP pump, closely followed by a 5-gallon pail. No buyer reviews yet, so the Safetech Flushing Kit (5-Gallon Lid) has to win you over on paper. The catch with this Safetech flush kit: without service valves on your heater, there is nothing to hook it up to. We'd pick it if you would rather flush it yourself than book a service call; otherwise, put it next to the 6699 Flushing Kit (1/4 HP Pump) first.
Before the Safetech Flushing Kit (5-Gallon Lid) goes in your cart, check your service valves: its 1/6 HP pump needs isolation valves with service ports on your heater to connect to.
Most makers name the descaler or the vinegar they accept, and some warranties depend on it. Check before you pour.
Look under the heater for two valves with small side ports on the hot and cold lines. That is where the flush hoses attach.
