Product review (1 stars): $100 lesson to not buy parts at Amazon
Complete junk - Plumber spent 1/2 hour installing it only to find the internal washer or valve was not properly and leaked under pressure. Took another 1/2 hour to remove and install another part.

So the $10 dollars I saved on this part compared to buying one at Home Depot or Lowe's ended up costing me an additional $90 in labor and then could not return the broken part as Amazon only allows 30-days to return parts.  Again, Home Depot and Lowe's offer 90-day returns as you are at the scheduling mercy of contractors or tradesmen.  Beware these cheap parts.
