Frequently Asked Questions

Does it fit a 100PESB valve?

Rain Bird lists a different diaphragm part for 100PESB. Use 208143 for the verified 100PEB application.

Is it a complete valve?

No. It is a replacement diaphragm assembly for an existing compatible valve.

Why Buy from Big Frog Supply?

Choose 208143 after identifying a 1-inch 100PEB valve and confirming that its diaphragm needs replacement. Its PEB-specific part number distinguishes it from the 100PESB diaphragm, helping you avoid ordering by pipe size alone.
