Almost gave up until I found this!
The Tankless Tool® NAV
It worked well for our Navien's tankless water heater! I was almost giving up on opening the cold water inlet filter as I couldn't find anything else to do.

Definitely Recommend!
The Tankless Tool® RWH
Easy to order, arrived in a timely manner, and best of all it works as shown. Quality material, perfect fit on the filter cap, and should never need need to be replaced. Unless I manage to loose it. It's highly unlikely that you can break the filter cap when using this tool. Definitely recommend.

Easy Ordering!
The Tankless Tool (RWH-XL)
Ordering products from “The Tankless Tool” website was seamless and very simple. The tools came in quick and I’ve already put them to use. I wish these tools were around 20 years ago when in was putting in tankless heaters but so happy I have them now to get out old filters from tankless heaters.
