Vapour Block
Drain sealer that prevents sewer gas odors and dry traps
This citrus-based drain sealer stops sewer gas odors and blocks insects from entering dry P-traps, ideal for infrequently used areas like cottages and cabins. It forms a vapor barrier that reduces water evaporation in both P-traps and sewer drains, even without a P-trap.

How to keep drain traps from drying out?
This easy-to-use floor drain odor stopper eliminates sewer gas smell by creating a vapor barrier on top of the water in the P-trap reducing the water's evaporation rate.
Product Information
What causes the sewer gas smell from floor drains in buildings?
This is usually caused by dry P-Traps. When a drain's P-Trap is functioning correctly it acts as a seal preventing odors and/or potentially explosive methane gases from entering rooms through the drains.
P-Traps typically dry out in remote areas where there is no trap seal primer or it is not functioning correctly. Without a constant supply of water, a P-Trap will eventually dry out leaving the drain fully exposed.
Trap seal primers are designed to provide a supply of water to replenish P-Trap for drains located in infrequently used areas. In some cases, they are a small piece of tubing which feeds water to the P-Trap when a sink is used or a toilet is flushed.
Without a properly functioning trap seal primer, maintenance personnel has to feed water manually every week or so to prevent the drain trap from drying out.
How to keep drain traps from drying out and avoid sewer gas smells?
Vapour Block is easy to use and seals in the water located in P-Traps by creating an evaporation-resistant floating seal that lasts for extended periods of time. Depending on the humidity level, Vapour Block can last 6 months or more, greatly reducing the amount of maintenance required.
Why use a floor drain sealer?
- Stops sewer gas odors
- For use on drains with no working primer
- Will not freeze, great for winterizing drains in seasonal cabins, cottages and country homes
- Has a nice natural citrus formula
- Slow evaporation rate keeps your traps sealed for a long time
- Creates a seal in the P-Trap of the drain preventing the water seal from evaporating
- Reduce maintenance in areas not being used frequently
How to apply it to dry drain traps
For initial treatment:
- Add sufficient water to fill the P-trap.
- Then add 16oz - 32oz (1L) of Vapour Block directly into the drain to seal in odors and prevent evaporation.
Recommendation for regular maintenance:
| 2" drains | 16 oz |
| 4"+ drains | 32 oz |
| 6"+ drains | 4 L (1 gallon) |
Repeat the above treatment when necessary.

No more stinky!
Got a tub I do not use, poured this in... no stinky for 3 months now.
Still have some on the shelf for when it gets stinky again.
Very happy.

It can be toxic
Did what nothing else good and that was stopped the noise in my drains

It works
This product works for down drains that do not get used regularly. If you use your drain regularly do not buy this because you will just end up rinsing all of your vapor block away! The price I paid for this is $$$$. It should not be this expensive
Luis Rosado
This really works for drains that are not used frequently
I used this for my house that I'm not leaving and the drains when you're not using them they get dry and could get insects or even a clog. Is really good and keep it odorless, this is not for unclogging drains people, you have to know the difference between clog remover and drain maintainer but having a maintainer it will help you prevent a clog in the future. I used it in the bathroom, kitchen and shower sink.

Good product.
This Vapour Block contains a good amount of the fluid. This is always good to have on hand.
Questions & Answers (3) Questions
Q: We would like to know what happens when the shower is used, does it just flush out the Vapour Block and then we'd have to refill it after every use? Please let us know, we've seen your youtube video and others are asking the same question: how long does it last IF the shower is used? THANK YOU.
A: Vapour Block is only for drains that are not frequently used. Vapour Block prevents the p-trap from drying out, stopping sewer gas smells. If you are using the shower every day then there should not be any smells coming from the p-trap in that drain since you have water going into it every day. If you are still getting smells in that shower drain then you likely have a different issue. And yes, it will wash away when you add a substantial supply of water to a drain that has been treated. Hope this helps.
Q: How long would Vapour Block keep a 4" drain from drying out? How about a 2" drain?
A: In any drain diameter, Vapour Block can last for months depending on the humidity in the room.
Q: My floor drain in the basement may be dried out, we have a metallic odour in the air. I have already put 2 cups of water in. the drain and a cup of javex, can I still add the Your vapour block to the drain?
A: Yes, VapourBlock is ideal for this application. I would pour a few buckets of water down the drain before adding VapourBlock to get rid of the Javex. VapourBlock will prevent the drain from drying out and stop those odors.
