New Bathroom Fan is Ineffetive


I installed the same bathroom fans in two different bathrooms. In one bathroom, the fan has suction and will hold a tissue against it. In the other, the fan has no suction - tissue does not stick. The old fan was like this as well.

My initial thought is not the fan itself, but the vent tube must have a leak. How hard is is generally to replace these tubes? I am wondering if the tube is something flexible causing lots of resistance. Other thought is a clog somewhere - is it best to take the fan out and stick a shopvac in the vent?

Can you gain access to the area above the bathroom ceiling, to check on the vent tube, it might be any number of things wrong.

An inspection would be my next move.

It might not be there at all, and insulation lying over the fan, or it might be plugged on the roof by any number of things.

Only way I am getting access to the vent tube is a ladder outside to look at the vent exhaust; otherwise I am cutting into my ceiling

I dropped one ceiling to find 3 90*s and a 45* bends before it left the room and one joint had come apart and dropped into insulation totally plugging any hope of ventilation. I moved the fan 12" and used one 45*

Was the door open when you tested the fan. There needs to be a source of air coming in before any air can go out. Just checking before you cut into the ceiling.

If the duct is flex, it's very possible there are too many turns or kinks. Flex duct is terrible for pressure loss. First think you might want to check is the where the vent exits the house. Did a bird make a nest in there?

Along the lines of what Bud suggested there should be a gap under the door for make up air.
If not it's like sucking on a straw with your finger over the tip of it.
The flap on the outside to keep stuff out could be stuck.
