Slow drainage from sink

Hi, we have recently moved into a house with a Taylex Home Sewage Treatment System, and the sink in the bathroom is draining very slowly. In my old life, I would have chucked a bit of Draino down and cleared it out, but I can't do that now. Any ideas on how to speed it up?

If you have decent water pressure, poke the hose down the drain hole (as much as you can) and seal it with hands, rags or whatever, and give it a blast.

Check your grease trap and grey water tank.

If its connected the same as our, all your drains will go via a grease trap to the grey water tank. Only the toilets will go to the treatment unit.

We had the same issue for some time but it would come and go. I tracked it down to the float switch in the grey water tank. The issue was the switch was activating to late and I just needed to move it deeper into the tank.

When the tank is empty the floor drains have about 2m of fall. When full about 100mm producing a very slow flow.

I just needed to make sure the tank emptied earlier to maximise the fall

Thanks everyone, I contacted the manufacturer as well, and they suggested Actizyme, so that might be my first port of call. :)

These blockages usually occur in the places they're "supposed" to, as in U bends and grease traps. If you can unscrew the U bend below your sink that might yield the simplest solution and a few gold nuggets if you're lucky. Beyond that, it's possible for a build up to start from a minor obstruction in any pipe with only a few degrees of slope, so location, location, location might be the key.

I like Gordon's solution. It could be very exciting :D

Would this work for slow draining baths too?

Yes to some extent. Actizyme pellets desolve fats and grease.
A slow draining bath could be hair as well.
Can't hurt to try though.

I've recently had slow draining water from a shower enclosure. Turned out to be root intrusion through a crack in PVC pipes.

Hmmm...I might give the enzymes a try and see if it makes a difference. Thanks!
