If you need it, you need it. Works great.
Bought this for an under-kitchen-sink install, to help keep grease out of a septic system. Seems to work very well. We did contact the seller a couple of times for advice, and they were quick to respond and we're very happy with the product

Works Exactly as Advertised
I bought this grease trap for my home kitchen and couldn’t be more satisfied. It handles up to 5 GPM and traps grease efficiently — even after heavy cooking days. Cleaning is quick; just open the lid and dump the collected grease. The design feels solid and well-made, and I appreciate the clear instructions included. Since installing it, my sink drains much better and I’m no longer worried about greasy buildup. This has made kitchen cleanup easier and given me peace of mind. Highly recommend it!

Well fit at home or at the business
The city code for the plumber changes since last few years: it requires the grease trap for the small business with 3 compartment sinks. The item fits perfectly for this purpose. Ease to install, save a lot of money if DIY Cover sealed for the bad odor (need to flush, to clean every 4 or 6 weeks, using grease trap cleaning tablets) Value for the price comparing to other models (steel, ....)

Works until it leaked. Leaked on both sides
Works, but is leaking. Leaks on both sides. Apparently it stays full as shown on picture. No wonder the smell builds up. The lid has a hole which traps water inside of it. It has a white plastic cork on it which can be removed. Slushing the water around to remove is a task. That too will eventually smell. I plan to add more clamps on the sides that leak. Hopefully that will fix the leak.

Works as advertised except…
This works as advertised. The enzyme tablets are recommended by me. I used easy disconnect unions in my installation. It catches the grease and the tablets eat the grease up. Cleaning is surprisingly easy. The female fittings supplied did not fit normal 2” pipe as advertised. I didn’t use them because I used the disconnect unions as recommended in the installation video. I couldn’t figure out what size pipe used in the USA or Canada would fit. (2” PVC/CPVC were too small for the fitting.) It was weird and the plumbing supply dept. couldn’t help.

Beseder will stand by their products.
Beseder is a stand up company. I had concerns, from reviews that were left, that the product leaked. I took the time and effort to properly seal the threaded joints, and had NO leaks whatsoever. The trap works beautifully, and is protecting my drain system. They were kind, helpful and generous, in sending me a new lid seal, just to have on hand, as well as some other parts, that I wanted to have, for maintenance, down the road.

No connectors included
Unit looks solid but we haven’t installed it as it does not come with the pipe connections so we haven’t installed to buy those separately
