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
Solution included. Everything for the first flush in one box: pump, hoses and the descaler.
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, a 5-gallon pail and the descaler, 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.

Our take
Our favourite thing about the Chromex Flush Kit (Solution + 1/6 HP Pump) is a 1/6 HP pump and 6 ft hoses, closely followed by the descaling solution in the box. No buyer reviews yet, so the Chromex Flush Kit (Solution + 1/6 HP Pump) has to win you over on paper. Our main reservation: 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 (Solution + 1/6 HP Pump) 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.
A 1/6 HP pump, 6 ft hoses, a bucket and about an hour. Our flushing and descaling guide walks through the steps.
