American Valve CondensateRx Condensate Neutralizer for Boilers and Tankless Heaters

For a high-efficiency boiler or tankless water heater that drains acidic condensate, the American Valve CondensateRx adds a dedicated neutralizing step at the drain line. Its low-profile design connects directly to the line, keeping treatment close to where condensate leaves the equipment.

The kit is made for installations that need a practical connection to common drain arrangements. Adapters support 1/2-inch hose barb and 3/4-inch PVC socket connections alongside the 1/2-inch FNPT connection.

With neutralizing media formulated for acidic condensate, CondensateRx helps protect drainage systems, septic tanks and landscaping from the effects of untreated discharge. Its stated capacity makes it suitable for boilers up to 220,000 BTU per hour.

Practical tips

Install the neutralizer directly on the condensate drain line, choosing the connection that matches the drain arrangement: 1/2-inch FNPT, 1/2-inch hose barb with adapter, or 3/4-inch PVC socket with adapter. The low-profile unit can be installed straight or vertically, at an angle of up to 30 degrees. This gives some flexibility when positioning it along the drain route.

For a boiler or tankless heater producing acidic condensate, the neutralizer provides treatment before the water reaches the wider drainage system. It is designed for use with high-efficiency condensing boilers and tankless heaters, with a maximum boiler size of 220,000 BTU per hour. Follow applicable local plumbing requirements when planning the installation, particularly where condensate neutralization is required.

Why it’s worth it

Some drain setups simply route condensate away, CondensateRx adds a purpose-built neutralization stage to that route. Its direct connection and multiple adapter options help integrate treatment at the drain line, while the compact, low-profile design offers flexibility in positioning. The neutralizing media is formulated for acidic condensate and supports discharge to drainage systems, septic tanks and landscaped areas.

Buyer feedback commonly describes the installation as straightforward and the product as functioning well. Opinions on value vary, so the clearest reason to choose this kit is its specific role: treating condensate from the listed heating equipment, with connections and capacity details to guide installation planning.
