Review: Great Value - Great product, works great
Review: Quality Check Valves - They work well for letting fluid through. They dont flow at first, but if you put some fluid through and add a little pressure they will flow. Once they have fluid in them they continue to flow. I think they just need the initial lubricity then all good.
