Georgetown GT-7 36D7 shower drain
Shower not draining intermittently, when not draining if turbo vent under sink in bathroom is removed You can feel air flow and water drains. Does not matter the level in the gray tank. I spoke with the manufacturer of Turbo vent,they didnít think the turbo vent was the problem but sent one anyway. I replaced the turbo vent under the sink closest to the shower however this did not fix the problem.
Iím new to RVíing, any help is appreciated.
