PVC Question

Rookie_4

WOW!! It was only a thought. It's in my house and I do clean the lousy metal flex that is there thats why I was looking for something more practicle. I do have a code book
527CMR4.00 (oil tech.) I'm not a plumber or I wouldn't be worried about cleaning it, I'd pay someone to do it for me with all my extra cash. LOL!! I'll go with the metal pipe set up Plumdog style.....Thanks for swaying that foolish thought.....ROOKIE

PVC Question

Would a 4" PVC pipe be OK to vent a clothes dryer? The cheap plastic flex hose can handle the heat alright, does it have a flame retardant that PVC pipe does not? I have about a 10' run that would be much easier to clean if it was a 4" pipe vs. the big slinky...........Thanks ROOKIE

As far as I know...

Plastic 'flex' has been outlawed in most cities. Where it hasn't, it should be. I worked a fire job that was the result of using plastic flex.

I'd stay away from plastic altogether. What's the point when you can use 4" metal flue or duct?

DO NOT USE PLASTIC!
Be safe!

Buy a code book

dryer vents must be metal; no screws; and the joints must be made in the direction of flow. The point is not to catch lint which may block the vent or catch fire. The vent terminal should not have screen in it. There are limits to how far and how many ells are allowed depending on code adopted in your area.

silly rookie

Tricks are for kids. 2003 International Fuel Gas Code section 613. See section 613.1 General, 614.1 Installation, 614.2 Duct penetrations, 614.3 Cleaning access, 614.4 Exhaust installation, 614.5 Makeup air, 614.6 Domestic clothes dryer ducts, and 614.6.1 Maximum lenght. Summary: Metalic only (no screws), 25' developed lenght max. (each 90 degree = 5' of developed lenght). As the plumbdog suggested "Buy a code book". Below are some pics of a fire we had in town in June where the resident located the dryer in the middle of the basement and used a combination of flex (plastic) connector, PVC pipe, and smoke pipe (total developed length (including 90 degree fittings) was 53'. I had to post the structure with the little UNSAFE STRUCTURE notices. Follow the manufactures installation instructions on the UL listed and approved appliance and PLEASE!!!!! Be safe.

encountered a Holloween dryer vent this past week!

For 30 years.......

Dryer, gas-fired no less, was vented through the floor - into a crawl space. The place looks like a haunted house(G). We'll be upgrading to a direct vent hi-e furnace AND venting the dryer too.

for sure it is a bad idea...

code or not. i have seen basements filled with lint,wall on fire, fire shooting out of the grills ( supply side) on a forced air heating system with the dryer tied into the return air...and a host of other abortions i am too tired to comment upon right now. straight shots one 90 or less metal seams sealed and taped. and hey...would be reasonable to mention cleaning them from time to time to the homeowner....just a thought
