How do I seal the pipe under my kitchen sink?
If the pipes under your kitchen sink are exposed, you may not want to fill the gaps around them with spray foam, which isn’t the most attractive material in the world. You can use caulk to fill gaps less than about 1/2 inch wide, and you can fill wider gaps by stuffing them with steel wool and caulking over it.
Why is the pipe under my sink leaking?
Arguably the most common reason you’ll find water beneath your sink is that your drain has a leak in it. Shifting plumbing lines, worn-out connections, or even pipe corrosion could cause fractures in the plumbing lines beneath your sink, which cause water that flows down your drain to slowly and steadily leak out.
Should drainage pipe be glued?
If you are trying to use PVC pipe to transport fluid or gas, PVC cement or special push-on fittings are necessary to assure there are no leaks. Not all applications require a permanent seal like this, however. Putting cement on all of these PVC joints could be time-consuming and messy.
Can you use plastic pipe under sink?
Most modern bathrooms contain plastic drain pipes made out of PVC, or polyvinyl chloride. This material transports nonpotable water down sink drains and other plumbing fixtures. Such pipes can be connected using threaded pieces or with glue.
Do you need plumbers putty to install a sink drain?
Some plumbers and installers favor plumber’s putty for installing drains, while others lean toward the more modern waterproof material called silicone caulk. Both plumber’s putty and silicone caulk provide a watertight seal for a sink drain.
What is P-trap under sink?
The p-trap under sink plumbing pipe serves the function of capturing a small amount of water inside your drainpipes after the sink is used. This plug prevents sewer gases from coming up the wastewater line and out the sink.
