Two toilets acting wierd

Hi @barmstrong

Low water level in a toilet bowl is indicative of a partially blocked sewer pipe or air vent.

If the other toilet is filling instead of draining this also indicates a blockage in the pipes somewhere.

You could try clearing it using a plunger.

If still no good then you may have to try using some other options¹ or calling a plumber as they should have the necessary equipment to clear drains.
