Gulley trap issues

[satchmolips]

Hi all,
My folks bungalow was built in 1989. After several months of problems with kitchen sink smells and floods then got to the problem today. The sink waste feeds into a gulley trap which is INSIDE the house. This was a gulley with a normal plastic cover where you cut hole for waste pipe and a drain type covers the other half, obviously for external use. It was totally full of grease etc. It had been originally sealed by plastic under the hard plastic cover. Question is; was it ever legal to have such a gulley in the house? Was there a better seal that could have been used for such a gulley? House was built by reputable buiding co and overseen by architect. Did someone foul up?
I have made an alluminium cover, hole for waste, sealed that all with sealant and then mortared over the lot with weak mortar. Guess I will have to break that when it needs cleaning in the next 20 years, unless there are any good tips out there.

Hmm!

In the sixties and seventies we sometimes used internal back inlet gullies. As you say one side was covered with a sealed inspection cover and the other connected the waste in a variety of ways.

The best was probably the one with a rubber seal and a rubberised hole for either 36mm or 42 mm waste pipe. So that when the waste pipe went in a tight seal was made around it, stopping any smells coming in.

Some houses had the inspection cover outside and an extended inlet going through the wall to pick up the waste.

All legal as far as I know. Check Bldg Regs for the time to be sure.

Train the staff not to discharge fat of any kind down the sink. It is by far the biggest cause of drain problems. When allowed to cool by mixing with cold water it solidifies and gums up the works. Good Luck
