Hi, we have a 2017 Corinium RB.
The sink in the bathroom drains really really slow.
if you help it with a plunger it drains ok.
The kitchen sink drains fine.
I have blown down the waste pipe and it feels as if there is some kind of valve / diaphragm in the pipe as there is some slight resistance then no resistance.
Does anyone know if this is the case
