Full listing title: Tankless Water Heater Flushing Kit: Brushless Pump, 2×6' Hoses & Toolbox
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.
Yourself: the kit gives you 6 ft hoses, 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 FILGAUR Flushing Kit, Brushless Pump listing:
No descaler included – use vinegar or your own.
25W DC24V motor delivers 290 GPH flow and 26 ft lift – strong circulation for effective descaling.
The included sturdy toolbox completely replaces a bucket as a flushing container, saving storage space.
Simply place the pump into the toolbox (acting as a bucket), use the brass adapter to connect the pump to the 3/4" GHT hoses, then attach the hoses to your heater's isolation valves.

What the FILGAUR Flushing Kit, Brushless Pump listing names:
In the box, per the listing: A pump, Hoses, A toolbox.
Check these figures against your heater's manual before you order.
On Sep 30, 2026, that price put it in the cheaper third 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).
The button opens the exact listing (ASIN B0H8NQQ6RG), where today's price, stock and seller apply.
Want the descaler in the box? The Chromex Flush Kit, Concentrated Vinegar (7.4/10) comes with it, per its listing.
Our take
The FILGAUR Flushing Kit, Brushless Pump keeps its spec sheet short, which suits skipping the service call for a job that takes an hour. No buyer has reviewed it yet, so our 7.1/10 comes from the spec sheet alone. Where it falls short: without service valves on your heater, there is nothing to hook it up to. We'd pick it if you want a flush kit for skipping the service call for a job that takes an hour; otherwise, put it next to the 6699 Flushing Kit (1/4 HP Stainless Pump) first.
Before the FILGAUR Flushing Kit, Brushless Pump goes in your cart, check your service valves: its 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.
6 ft hoses, a bucket and about an hour. Our flushing and descaling guide walks through the steps.
