I posted this on the Screwfix Community Forum but depsite many views, there were no replies!
My wife is a wheelchair user and we previously had a toilet fixed to a plinth to raise it so she could transfer more easily. We have had it replaced with a comfort toilet which is the same height as the previous one (including the plinth).
The waste pipe outlet was lower than the previous one so the builders made adjustments to the pipework.
The original cistern was kept.
It gurgles a few seconds after flushing which lasts for a good 5-6 seconds. There is no sign of air bubbles in the bowl. There is no blockage in the waste pipe and water flows freely into the drain. They have also replaced the flushing system.
However, we have discovered that if the cistern handle remains down after flushing, the gurgling is much quieter and lasts for 1-2 seconds at most! They suspect the new toilet is the problem (for whatever reason) and this morning brought an old one, put it on a temporary plinth and the problem disappeared. They have admitted defeat! Clearly, the new toilet and old cistern do not get on!
Before I contact the supplier for advice, can anyone enlighten me as to what might be the problem?
This is the new model:
