Roof Drain Repairs

[Lorenzo Poletto]

I am trying to find info about a roof drain repair kit that makes replacing lead seal roof drains unneccessary. I heard that someone had developed a fiberglass or PVC insert that fits in the drain from the roof side and is sealed to the bowl with silcon caulk. If this is true how do I get infromation? No one in the Colorado Springs area has heard anything about it….if it exists. Thanks.

What are you trying to accomplish. The cast-iron roof drain bodies are almost indestructable, and any insert would still be relying on it for its ultimate leak protection.: I am trying to find info about a roof drain repair kit that makes replacing lead seal roof drains unneccessary.

We have sold over 8,000 U-Flow retro-fit drains over the years. You simply drop the U-Flow drain insert into your existing drain pipe and expand their mechancial seal with a screw driver. The seal creates a very positive barrier to water backing up underneath the existing roof drain. You then simply flash the new insert drain per standard roofing details.

Thanks.Dear Sir: To accomplish hte repair that you are after the only true way to repair it is to remove the old lead joint that has been installed by a licenced plumber and re-seal the connection to the piping system that carries the water away to the storm sewer system. You can dig the old out with an awl, ascrewdriver, or thirdly by burning th eold lead out. The last method is to dangerous most time for the amateur to try. when all of th eold lead and oakum has been removed, you can repack the joint with white oakum and repack it down to form a water tight seal and top it off with a coat of molten lead at least one inch thick from the top of the packed oakum to the top of the lead joint. Melt enough lead so as to make one pour and not to place layers of lead causing the joint to leak. After the lead has hardened, about one minute, repack with a packing iron and a hammer that is about 10-12 oz. so not to crack the spigot or bell of the joint. The lead should pack about 1/8-1/4. After this you can top the joint off with some PURE silicone and forget about ever having htis problem again for at least 100 years. I am a licenced jorneyman plumber and as well as a member of plumbers local 93, one of fastest growing local in the US. I do nothing but commercial plumbing and repair these problems all the time and know only the correct way to do them. Once you have invested in gadgetry and all the rest you would have done better to do the repair the correct way. Yours, Bryan H. Groves please respond when you have received this message.
