### ⭐⭐⭐⭐⭐ Easy to install replacement part.
*by J***N on June 8, 2025*

My sprinkler system needed this replacement part and this was easy to install and didn’t need to hire anyone to do it.

### ⭐⭐⭐⭐⭐ Easy fix
*by D***Y on April 23, 2025*

Didn't witerize my sprinkler system properly last year and this year my Wilkins 420 backflow valve was leaking when I turned on supply water. Kit was literally 3 parts that went in same way old parts were removed in 5 minutes. Only tool needed is a channel locks plyers or pipe wrench. Super easy and worked like a charm . A bit pricey but better than spending 300dollars for a new valve I suppose
