All the screws are sealed on the outside with silicone sealant. Also, a bead of silicone on top that support piece that twists around the pipe. Pipes are installed in proper direction, so its not leaking in the pipe assemble joints. Every pipe seam in the garage drips water when it rains.

I cant figure out where it comes in. Id rather not get up there with a hose. It only leaks when there is a lot of rain. Either very hard rain or just a long rain.

Ideas?

First of all, that's NOT chimney. It's INTERIOR connector pipe.
It's not meant to be exposed to the elements.
Secondly, your set-up is TOTALLY unsafe & non-compliant.
Your insurance company will void your policy if they see what you have there.
You need to redesign your system & include Class A from the wall pass-thru to the cap.

Not only that, but every pipe section in the system is upside-down. Totally unsafe and non-comlpliant either way, but upside-down pipe joints is the reason it's leaking.

Oh but they are...stove pipe is meant to be installed male end down, or toward the stove...which will probably make your water issue worse since it isn't meant to be outside.

Unless that’s double wall, which it doesn’t appear to be, then they are upside down. Stove pipe goes male end down, so condensing exhaust (creo) drains down into the stove, rather than leaking out thru the joints. Of course this would make your rain problem worse, which is just one of perhaps a dozen reasons that type of pipe is not legal for outdoor use.

DIY installs are fine, it’s one of the primary functions this forum serves. But you really need to go back and do some reading, before tearing out that mess and starting over. Outside should be all class-A stainless, black stove pipe is for indoor only and male end down, approved thimble, and likely an appliance adaptor at the stove collar. Buy all components from a single manufacturer for best chance of it all working together.

There are some good install threads here, with an hour or two of reading, you’ll have most of the info you need, and know which questions to ask to complete that install.

Probably no need to continue jumping all over the guy. He just needs to do some reading on proper installs, I think this forum has a few stickies and articles to get him started, he’ll get this right.

They are definitely upside down. Creosote is supposed to drip down the pipes back into the stove. This is impossible with the way you have your pipes. Male ends should be pointing downward.
