What it's made for: a condensing tankless that drains to a floor drain or a septic tank.
Two condensate neutralizers close to it on our rating, each with a dated price.
What it has going for it
Neutralizer. Condensing units make acidic water. The media raises its pH before it hits a cast-iron drain or the septic tank, and it needs a refill now and then.
On Sep 30, 2026, that price put it in the cheaper third of the 8 condensate neutralizers we have a recent price for.

Our take
The best thing about the American Valve CondensateRx Neutralizer is neutralizing media for condensate. No buyer reviews yet, so this American Valve condensate neutralizer has to win you over on paper. The catch with the American Valve: no word on the exact models it fits. We'd pick it if you own a condensing tankless; otherwise, put it next to the Lazenta Neutralizer Kit (804000074) first.
Before the American Valve CondensateRx Neutralizer goes in your cart, check your model number: it is listed for specific models, and fit is model-specific.
Find the model and part number in your heater's manual and compare it with the listing.
The media gets used up. Check the replacement interval in your heater manual and put it on the calendar with the yearly flush.

On our rating, the American Valve CondensateRx Neutralizer comes out ahead (7.3 vs 7.2), so it is the one to start with.
We rate it 7.3/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.
Its listing states neutralizing media for condensate. These are the seller's figures, not our measurements: whether it fits your exact heater is worth confirming first.
Your exact model: find the model and part number in your heater's manual and compare it with the listing. Refills: the media gets used up. Check the replacement interval in your heater manual and put it on the calendar with the yearly flush.
