    This product works great for my small local bakery to meet city requirements! Very easy to install with no plumbing experience! Product shipped fast and is GREAT quality!
    I was looking for a small grease trap for my hotdog shop. I found this one it was perfect and the health department was pleased.
    We needed a grease trap for our 3 bay kitchen sink to satisfy the health inspector. Perfect size and works great. We would purchase this grease trap again.
    My only complaint- one side was threaded wrong. However we still made it work. It’s the perfect size for our food truck! The price is great compared to others. It is heavy though.
    When I decided to making my selection for the purchase of a grease trap with the measurements that I have and the limited amount of space I chose the watch WV for THD 8 pound grease trap with threaded connection it was small enough for the area that I had. It's well built and my my plumber, he loves it. It meets my city code for my use.
    This grease trap is a nice affordable option to the same exact thing you would buy from a dealer for FAR more. Works like a charm
    We just installed this grease trap and it seams to be working well. The flow reducer is a bit much and the basins take a while to drain. I opened it once it is definitely intercepting grease.
    My plumber loved this. Easy for him to install. It came with all the parts so there was nothing extra for him to purchase. It is perfect size for my bakery. Does not take up a lot of room and easy lid to remove.
    don't know much about grease traps, but i bought this for my small bakery. i guess is doing its job. i have been using it for almost a year with no major problem..i guess one of these days i'll have to clean it
