We moved into our house in December and noticed a problem with the main bathroom lavatory straight away, what with other priorities related to the house move, Christmas etc. have only just turned my attention to this to try and find a solution.
Symptoms are :- water level in toilet pan is low a lot of the time, when the toilet is flushed the water level drops even further before refilling the pan and is (50% of the time) accompanied by a 'sucking' noise as the pan empties. ( have to say the toilet has never actually failed to empty at any time).
Research on line suggested that the problem was likely to a blockage somewhere in the drain outside so I finally summoned up the courage today to open up the inspection cover in the garden and found no sign of a blockage. Looking at the soil stack, the bath and washbasin outlets connect to the soil stack just below where the toilet connects - there is no problem with the water flow from the bath or washbasin. While the inspection chamber was uncovered I filled the bath and then pulled the plug and watched the water flow into the inspection chamber and everything seems fine.
So, given the above, does this focus the attention back to the soil pipe between the toilet pan and the soil stack? and if so, would it be advisable to try plunging the toilet pan?
One further thing which may be relevant, when you start to pee into the toilet pan you can hear water beginning to trickle as the level in the pan rises, I have checked and it is not water running into the cistern so it must be the increased water level in the pan running down the soil stack.
Appreciate any advise. Thanks
