Explain Accessible Metal Check Valves

What happens here

The check valves, including the 'check balls,' are now easily accessible from the outside of the unit. Previously, these components were plastic and located inside the casing, making them prone to wear and difficult to service. The new design allows users to 'take those balls out' and wash them off. Furthermore, the valves are now made of metal, ensuring they 'don't strip out' when being put back in, significantly enhancing the product's durability and long-term reliability.

Goal: The improved accessibility of the check valves is explained, noting they are now metal for increased durability and easier servicing from the outside, preventing common issues like stripping.
