FAQ
What size inlet do these screens fit?
The H98-510-S screens are designed for the standard 1‑inch inlet found on most Rinnai tankless water heaters. They provide a snug fit without the need for additional adapters.
Can I install the screens myself?
Yes. Installation requires only basic hand tools. Shut off the water supply, remove the existing screen, insert the new IGIUA screen, and re‑secure the housing. Detailed instructions are included in the package.
How often should the screens be replaced?
Replacement frequency depends on water quality and usage. In areas with hard water, we recommend inspecting and replacing the screens every 12‑18 months to maintain optimal performance.
Do these screens affect water flow rate?
The screens are engineered to provide effective filtration while preserving the original flow rate of your heater. Users typically notice no reduction in hot water output.
Installation Guide
Begin by turning off the water supply and relieving pressure in the system. Locate the inlet housing, usually positioned near the cold‑water connection. Using a screwdriver, remove the existing screen carefully to avoid damaging the housing threads. Align the new IGIUA screen with the inlet opening, ensuring the filter side faces the water source. Press the screen firmly into place and re‑secure the housing with the original screws. Finally, restore water flow and check for leaks. The entire process generally takes 10‑15 minutes for a professional‑level result.
Maintenance Tips
Regular inspection of the filter screens helps identify sediment buildup before it impacts heater efficiency. If you notice a decrease in water pressure or hear unusual noises from the heater, remove the screens and rinse them under running water. For heavily contaminated screens, replace them with the spare units provided in the 2‑pack. Keeping the screens clean not only sustains performance but also reduces the likelihood of costly repairs.
Environmental Impact
By extending the service life of your tankless water heater, the IGIUA filter screens contribute to reduced energy consumption and lower waste generation. The plastic used in the screens is recyclable, and IGIUA encourages customers to recycle used components through local recycling programs. Choosing these screens supports both household efficiency and broader sustainability goals.
