Weil McLain 383-500-631 Kit

The Weil-McLain 383-500-631 Condensate Neutralizer Kit is a vital component for high-efficiency condensing boiler installations, specifically designed for Weil-McLain Ultra and GV90+ Series units. This kit prevents acidic condensate from damaging residential plumbing systems and local septic infrastructure by raising the pH level of the discharge before it enters the drain. Engineering for durability, this acidic condensate neutralizer utilizes magnesium oxide pellets to treat the corrosive byproduct common in modulating condensing boilers. Proper integration ensures compliance with local building codes that mandate corrosion protection for piping systems. For service technicians, this kit is an essential preventative maintenance solution, providing the necessary pH balance to handle the heavy load of high-output hydronic systems. This OEM Weil-McLain part ensures seamless fitment and consistent flow rates, maintaining the integrity of the secondary heat exchanger drainage path without risking restricted flow or system backup issues.

• System Longevity: Protects cast iron, copper, and PVC drain lines from the corrosive effects of low-pH condensate.
• OEM Compatibility: Specifically engineered for a precise match with Weil-McLain Ultra and GV90+ gas-fired boilers.
• Code Compliance: Meets environmental regulations regarding the discharge of acidic wastewater into municipal sewer systems.
• Easy Installation: Includes the essential fittings and media required for a standard inline configuration.
• Reliability: Designed to maintain optimal flow rates to prevent condensate backups that could trigger pressure switch errors.

How often should the neutralizer media be replaced?
The media should be inspected annually and typically replaced when the pH level of the discharge drops below 5.0 or when the pellets have diminished to approximately 25% of their original volume.

Is this kit compatible with other boiler brands?
While designed for Weil-McLain Ultra and GV90+ units, its operation is based on Flow-Through principles; however, always verify BTU output and condensate volume compatibility against the equipment specifications.

Can this be mounted horizontally or vertically?
This kit is designed for horizontal installation to ensure maximum contact time between the condensate and the neutralizing media for effective pH adjustment.
