Full listing title: Chromex Tankless Water Heater Flush Kit with NSF Certified Liquid Descaling Solution and Right Angle Inlet Hoses & 1/6HP Extra Strength Pump
Rated from the listing's specs, no buyer reviews yet
What it's made for: a hard-water house that flushes every year.
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, 6 ft hoses 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 Chromex Flush Kit, Right-Angle Hoses listing:
The right angle hoses allow you to easily attach the hoses to the tankless water heater with easier positioning.
Its citric acid based, and solvent free formula is safe for use with most metals, PVC, Rubber and ABS plastic hoses and materials.

On Sep 30, 2026, that price put it around the middle of the 10 flush kits we have a recent price for.
The descaler isn't in the box, so add a bottle (or a few gallons of vinegar, if your manual allows it).

Want the descaler in the box? The Chromex Flush Kit, Concentrated Vinegar (7.4/10) comes with it, per its listing.
Our take
We like the Chromex Flush Kit, Right-Angle Hoses for a 1/6 HP pump and 6 ft hoses and a 5-gallon pail. No buyer reviews yet, so this Chromex flush kit has to win you over on paper. The catch with the Chromex: 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 Chromex Flush Kit (1 Gallon Solution) first.
Before the Chromex Flush Kit, Right-Angle Hoses 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.
