How To Clean Dryer Vent Under Slab

I don't see a problem with PVC what is the length?

Why should it be okay just because in encased in concrete? It still has the potential to ignite. How do inspectors keep up with exceptions should more than one contractor that make the same mistakes over and over?

This is not only a violation of the code but the manufacturer's standards which are usually less restrictive than the code.

Apparently he's asking for forgiveness than permission.

We use plastic from the dryer to exhaust vent.

Rider Rick, I believe you but that is not permission or an exception to allow the violation and risk life and property.

Gregg good point but one thing that immediately comes to mind is the kitchen exhaust is opened at both ends and cooking is usually attended to whereas the dryer connection is concealed and should blockage occur the potential of fire to spread is high with the dryer unattended.

I would have a problem with a screen at the end of a dryer vent but not with PVC.

I allowed PVC for ducting for bathroom exhaust fans.

Greg,

Would you quote IRC M150.1 for me.

M150.1 says you can't use plastic venting from dryer to wall?

kyhowey,

A good meomory aid would be for the contractor to jackhammer up the

slab and replace the underground pvc piping and install above slab.

Also, the window wells typically get filled up with landscaping debris

over time, plus the well itself will function like a cystern during rain

/ snow events. What does Aaaaaahnold say, " ..bad idea!" :eek:

Greg,

In the code is there anywhere it says you can't use plastic ducting from the dryer to the wall?

Greg,

So I understand you correctly in the International Fire Code a plastic flex dryer duct that is sold at Home Depot to hook up to your dryer is not to code?
