Lochinvar & A.O. Smith 100291510 Cartridge

The Lochinvar & A.O. Smith 100291510 Cartridge is a critical OEM maintenance component designed specifically for the PP-AS20 Product Preservers anti-scale system. As a veteran technician knows, hard water scale acts as a thermal insulator, significantly reducing heat transfer efficiency in tankless water heaters and boilers. This replacement antiscale cartridge utilizes a specialized media blend that chemically sequesters scale-forming minerals like calcium and magnesium, preventing them from precipitating onto heat exchanger surfaces. By maintaining a clean internal flow path, the 100291510 cartridge ensures domestic water systems operate at peak performance without the need for frequent chemical descaling or flushing cycles. Engineered for high-demand residential and commercial applications, this Product Preserver replacement is essential for protecting sensitive internal components from mineral buildup. Regular replacement of the Lochinvar 100291510 ensures consistent flow rates and helps prevent premature equipment fatigue caused by localized hotspots and restricted waterways in hard water environments.

• Optimized Heat Transfer: Prevents hard water scale buildup on heat exchangers, maintaining the energy efficiency of tankless water heaters and boilers.
• Chemical-Free Protection: Sequesters minerals into an inactive form without adding harmful chemicals or requiring electricity for operation.
• Extended Equipment Life: Protects internal copper and stainless steel components from the damaging effects of mineral calcification.
• Simplified Maintenance: Dramatically reduces the frequency of manual descaling flushes required for high-efficiency water heating units.
• Exact OEM Fit: Specifically calibrated for the PP-AS20 anti-scale system, ensuring proper bypass flow and treatment concentration.

When should the 100291510 cartridge be replaced?
For standard residential use, the cartridge should be replaced every 24 months. However, in high-volume commercial settings or areas with extreme water hardness, more frequent intervals may be necessary to maintain effective scale inhibition.

Is the 100291510 compatible with all water heater brands?
This cartridge is an OEM replacement for the Product Preservers PP-AS20 system. While that system can be installed upstream of various brands, you must verify that your filtration housing is the PP-AS20 model before ordering.

Does this cartridge restrict water pressure?
When installed correctly in the PP-AS20 housing, the cartridge is designed to handle high flow rates with negligible pressure drop, supporting the demands of large-output tankless units.
