What can be used to seal the No-Caulk flashing to the rooftop?
100% exterior or marine rated silicone caulk can be used to seal plastic base flashings to the rooftop.
What flashing is used for single wall metal exhaust pipes attached to water heaters and furnaces?
Single wall metal exhaust pipe should never be used to vent a water heater or furnace when the pipe passes through a combustible material of any kind due to risk of fire. The flashing rain collar will melt or warp if exposed to these temperatures passing through the single wall pipe, and loose the water tight seal it is designed for. All water heaters and furnaces not listed as high efficient should be vented using rated B vent pipe. B vent pipe is doubled wall pipe which isolates most of the exhaust heat to the interior pipe. All Oatey flashings are safe to use with B rated vent piping.
What is the manufacture warranty for flashings?
With the exception of the Master Flash and Retro-Master Flash, all flashings have a one year warranty from the date of manufacture. Flashings cannot be guaranteed for the life of the roof due to varying roof life spans, and potential adverse conditions (i.e. extreme heat, extreme cold, hail). If a roof is replaced the flashing should be replaced at the same time. Master Flash and Retro-Master Flash are the only exceptions; if installed properly according to industry standards, they have a 20 year warranty from date of manufacture.
Is there a roof flashing for corrugated (engineered) roofs?
Yes. The Oatey Master Flash and Retro-Master Flash are designed to conform to most roof profiles.
How is a rain collar installed?
After the correctly sized collar has been selected; you will apply a 100% exterior or marine rated silicone caulk to the top of the existing rain collar attached to the roof flashing, and also to the underside of the new rain collar. Slide the new rain collar down over the pipe to the top of the existing collar. Press the new collar down with enough pressure to seal the two together without collapsing the seal around the pipe.
How is the flashing size determined?
The size of the flashing is determined by the OD (outside diameter) of the pipe penetrating the roof or sidewall of home or building. Never try to slide a smaller flashing collar over a larger pipe because it will cause fatigue failure in the collar. Never install a larger collar over a smaller pipe and try to use sealant to fill the void. Any sizing miscalculations will lead to leaks within the home or building.
Does Oatey offer a washing machine or ice maker valve that can easily attach to different pipe materials without adding additional adaptors?
Oatey is pleased to announce that we do offer such a valve for washing machine and ice maker connections; it is called the “Push Connect Valve”. These valves come as part of our Outlet Box collection. They are designed to easily accept ½” Copper, CPVC and PEX pipes, by simply pushing the ½” pipe into the Push Connect Valve Fitting. If for any reason the pipe needs to be removed after installation, no problem. Simply use the quick release tool to remove that section of pipe, and insert the new piece of pipe. No need for solder, pipe joint compounds or thread sealant/Tapes; just cut, de-burr and chamfer (bevel) pipe end before pushing and connecting the pipe.
Why do some valves have hammer arrestors?
Hammer arrestors are designed to help with water hammer (banging noises) in the water lines when a washer or ice maker are in use. When the appliance’s quick closing valve shuts off, it will exposes any loose piping in the water supply system and make banging sounds. The hammer arrestor helps absorb the shock and minimize or eliminate the banging sound. Oatey manufactures a full line of pipe supports which can assist in securing the loose pipes.
Does Oatey offer fire rated boxes?

Does Oatey offer a UL listed washing machine outlet box or ice maker outlet box?
