Downstairs loo is blocked, there is a soil stack right next to the toilet. When I unscrew and remove the soil stack access "thingy" water flushes no problem and no blockage.
When i screw the part / thingy back into the soil stack the water does not flush in the toilet and drains very slowly.
I'm guessing there is an air issue, I've checked the outside of the house, i can't see a soil stack vent.
