Review on 💦 Rinnai H98-510-S Tankless Water Heater Inlet Screen Assembly - Enhanced Water Heater Parts and Accessories for SEO by Mark Cole

I do not recommend Rinnai as the customer service is terrible, too many examples to list. This part is perfect for HW Tankless. I replaced my 12 month old cartridge filter. I would buy it at least once a year and clean it monthly. Use silicone or o-ring grease and tighten by hand and a little more with a rag or paper towels. Do not overtighten with channel fasteners as it will break over time. The sealing ring will be tight. This pre-filter will clog if you have sump or household filters that bleed carbon or sediment into city water. Also, the post filter is brown and doesn't do anything. If you have a Rinnai tankless system, you will have white crystals after being heated by sudden heat, so you should clean filters and faucet fittings. Every 6 months.
