Sealing Sink Drain With Silicone

Use Temporary Methods To Patch Them

âsiliconeâ? INSTEAD of âplumbers puttyâ? on kitchen drain basket

First of all, disconnect that P-trap by using an Allen wrench screwdriver to unscrew whatever connects it to the sink. This way you can clearly find where the problem is and find the right way to fix it. For example, epoxy putty and tape can be temporary fixes for a pipe thats leaking.

Epoxy putty

Apply a 2-part epoxy putty for the most durable temporary fix. This will harden in about 15 minutes, making it good for small jobs like patching up holes or cracks where water is leaking out. It wont last forever thoughyoull need to reapply from time to time as needed.


If you dont have those tools on handor if theyve been lost or damagedyou can always use plumbers tape instead. Plumbers tape is just as effective as plumbers putty but much easier to use: just wrap a piece of tape around each threaded connection between your pipes and P-trap.

Wrap self-securing silicone tape around the pipe if theres a minor leak. This will stop water from coming out of the pipe without having to do any serious work on your part. Just be sure that the tape has been applied properly. This will help keep water from moving into other parts of your home while you work on repairing your plumbing system.

Pros/cons Of Silicone Caulk

As we just saw, silicone caulk is pretty versatile. This means that it can be used to repair cracks and holes of all sizes.

It’s also inexpensive, which makes it great for smaller projects. Plus, it’s super easy to use.

The only downside is that you’ll need to consider how permanent you need the fix to be. Silicone caulk is extremely difficult to remove once it’s been applied, so any mistakes could take time to undo.

Why Sealing Kitchen Sinks Is Necessary

Creating a seal around the kitchen sink is a simple step often overlooked by DIYers. Sealing around kitchen sinks or sealing a sink drain with silicone will keep your sink in good condition and prevent future problems. Using a high quality, waterproof sealant prevents water and debris from entering the gaps. If you want to avoid mould and water damage, sealing kitchen sinks is a must.

Is Plumbers Putty Better Than Silicone

Answering the question of whether a plumbers putty is better than silicone is difficult. The answer is circumstantial and will change in response to different factors.

Plumbers putty is always a great choice to seal leaks and connect fittings. But as the name does imply, you should only use this putty on plumbing fixtures and accessories. While you have more available uses for silicone caulking.

How Do I Seal The Sink Basin Opening

I purchased a new bathroom sink and faucet and set everything up according to instructions. The faucet instructions told me to use silicone for the drain lip .

Anyways, underneath where the pipe comes out is a rubber gasket and I’ve used the plastic screw on the drain pipe to seal the gasket against the underside of the sink, but when I put a little bit of water in it, some water leaks out from between the gasket and the sink. I’ve tried tightening it as much as I can and it still leaks.

Should I be putting silicone or plumbers putty between the gasket and the sink? If possible, I’d like to avoid taking the drain lip off because I’ve already sealed it there. What should I do?

Here is a picture of the underside of the sink:

UPDATE: It turns out that the problem was that the rubber “washer” was actually threaded itself. I’m not sure if they are always like this, but I didn’t realize that it was threaded when I was assembling everything. So I assume that what was happening originally is that when I didn’t have the rubber washer close enough to the basin when I started tightening the nut that it was moving the the threads out of alignment or something and not making a good seal. Once I turned the washer a few turns upwards, then tightened the blue nut, it made a proper seal. All without using a bunch of puttey or silicone.

UPDATE2: So it has been 10 months and it hasn’t leaked. Problem solved.

UPDATE3: It’s been 8 years and it hasn’t leaked.

Do You Need Plumbers Putty For Garbage Disposal

Silicone Tub Stopper, Premium Bathtub Drain Stopper, Sealing Sink ...

Yes. Plumbers putty is commonly used to seal the sink flange to the sink, but silicone will provide a more reliable seal. With silicone, theres almost no chance of the flange leaking now or later. Without a plumbers putty, you can still have a mess in your garbage disposal drain.

If youre replacing your garbage disposal, you do not need to worry about the flange. Silicone is more expensive than a plumbers putty, but it is preferred by professional plumbers because it has better adhesive properties and keeps water from leaking into the cabinet under the sink.

Also, its completely waterproof so theres no chance of water leaking into the walls or cabinets. To seal those gaps, silicone will be a better choice than plumbers putty because it cant be ruined by rust, water, or chemicals like bleaches or hot drain cleaners.

If you are installing a new garbage disposal, silicone is a good idea since its basically permanent and wont leak when you put in a new disposal or any other type of appliance for years to come. You also dont run the risk of it falling off and creating something else for you to fix later on down the road.

    What is plumbers putty?

    If you need to stop or prevent leaks around your faucet, sink or tub drains plumbers putty is the product you need. Plumbers putty is a sealing staple for professionals, homeowners and DIY-ers alike. This easy-to-use product will prevent the migration of water between two rigid surfaces, keeping your fixtures leak-free.

The product is ideal for setting faucets, sink basket strainers, shower and pop-up drains. Its easy to wipe away after installation and will not be visible from the outside of the plumbing fixture once installed.

    Unlike some other sealants, plumbers putty remains soft over time and can be easily modified after its first application. Because plumbers putty is oil-based, it can stain porous materials, such as granite, marble, quartz and sandstone. For application on these surfaces, use a stain-free plumbers putty, as this product is oil-free and will not stain the porous material.

    Is Plumbers Putty The Same As Silicone Sealant

    When it comes to fixing a leak, there are few things as frustrating as when you cant seem to put the pieces of the puzzle together. One of those pieces might be the sealant thats meant to keep water from seeping through the cracks and into your home.

    First off, plumbers putty is made with a thicker consistency than silicone sealant. This makes it perfect for use in areas where you dont want any water getting through, like around pipes or around electrical wiring.

    Should I Use Silicone Or Plumbers Putty For Sink Drain

    Yes. The primary distinction between plumbers putty and silicone for sink drain is the ease with which the substances can be manipulated or removed. Plumbers putty is very easy to work with in tight spaces, and its also very easy to remove. As a result, silicone putty is superior for waterproofing, despite being more difficult to work with.

    Plumbers putty is a good solution for sink drains because it has the ability to become malleable when heated. This is a great benefit for tight spaces because plumbers can use a heat gun to make the putty stick to any surface, including curved surfaces that are difficult to reach or see.

    Plumbers putty tends to harden immediately when it contacts the air this makes it easier to apply and remove than silicone. Silicone tends to stay hardened in certain areas of the sink drain, making it more difficult to remove, but silicone is much more waterproof in comparison.

    Tips For Using Plumber’s Putty

    While plumber’s putty is better than caulk in some situations, it’s not a universal caulk alternative. Do not use plumber’s putty where you need adhesive strength or where you need a watertight seal in exposed areas. Follow these other tips for the best results:

    • Plumbers putty should be pliable and easy to roll. If it’s too hard to roll or it cracks when you try to shape it, it is too old and dried out. Get a new tub of putty.
    • Keep the tub of putty sealed tightly so the putty will last as long as possible before getting hard. It eventually dries out in the tub, but this can take years.
    • Read the label of the plumbers putty before using it on porous surfaces. Plumbers putty is petroleum-based and can stain some materials, such as granite. The directions on the container of putty will let you know what surfaces it can be used on. There are stain-free forms of plumbers putty for use on stone and other porous materials.
