Plumberpro :

Hi , is it a new system and or has any work been done on the soil( waste water ) pipe?

Customer:

No, property is 100's years old, rest of the toilets in the property are fine - we are connected to a septic tank which was emptied a few months back.

Plumberpro :

Its a strange one. Have you replaced them loo or any part of the cistern?

Customer:

no, just flush the system, everything washes away, then the level of the water in the bowl continues to drop leaving a shallow amount of water at the bottom, repeat the flush, same thing ...

Plumberpro :

Some toilets are syphonic . they need a special valve in the cistern . if you had it replaced with a normal one this could be the problem

Plumberpro :
