He graduated with a degree in Global Business Management in Tub drains are typically two pieces: the drain and the overfill tube. Installing a tub drain requires fitting the drain and overflow tube, which piece together to form an L-shaped unit, to the tub.
The overflow tub secures to the top with screws through the cover plate that grabs the overflow tube. The drain is secured to the tub by screwing the drain basket down from inside the tub but requires sealant. Sealing an existing or new drain basket is easily done with plumber's putty.
Remove the pop-up drain if installed. Most pop-up drains unscrew by firmly grasping and rotating the drain while in the up position. Some pop-up drains have a horizontal screw in the side of the drain. Lift the pop-up drain and rotate it until you see the screw.
Remove the screw with a screwdriver or Allen wrench, allowing the pop-up drain to lift out. Some types require you unscrew the top cap by holding the larger base of the pop-up drain to expose a retaining screw. Unscrew the existing drain using a basket wrench, which is a specialized tool that looks like a short-metal pipe with a rod running through it horizontally.
The tool is available at any hardware store. Press the tool down into the drain to grab the edges of the drain and rotate. The drain will loosen and come free. Do not fully remove the drain. Dry the drain and tub with a towel to remove any residual moisture. Remove any existing or damaged gaskets or putty from around the drain basket. Wrap the roll of putty around the drain and pinch the ends together. Press the roll beneath the lip of the drain basket.
Twist the basket down using the basket wrench until the basket is flush with the surface of the tub. The putty will squeeze out the sides of the drain.
Remove excess with a screwdriver or scraper. Reinstall any pop-up drains the opposite of the removal. Pin Share Tweet Share Email. Step 1. Step 2. Step 3. Step 4. Step 5. Step 6.Plumbing fixtures, such as bathtub drains, are common sources of water leaks. Sealing or caulking the bathtub drain helps guard against water damage. The material used to seal this type of plumbing fixture depends on the accessibility of the drainage pipe below your bathtub.
The area outside the actual drain may also require sealing to help insulate the tub area. Check for an access panel below or beside your bathtub that allows you to reach the piping beneath the drain. If you can access this part of the drain, the best sealant to use is plumber's putty. Plumber's putty forms a tight, waterproof seal in wet areas. If you are unable to access the underside of the drainage pipe below the tub, you can use silicone caulking on the exposed area of the drain to help create a watertight seal.
Once the caulking dries, it forms a firm seal that won't wash away. Plumber's putty is a thick, moldable substance that forms a tight seal between the underside of the drain lip and the surface of the bathtub. To apply this material properly, you must first loosen the drain lip by unscrewing the nut below the bathtub drain. This nut attaches to the drainage pipe underneath your bathtub. Squeeze out the putty into a thin rope that measures approximately a quarter-inch in diameter.
Place the putty beneath the loosened drain lip. Working in the area beneath your tub, tighten the nut below the tub to pull the underside of the drain lip firmly against the surface of the tub. Remove any excess putty before it dries. If you can't reach the underside of your bathtub, an application of waterproof silicone caulking around the exposed part of your drain will help reduce the risk of leaking that can occur when water seeps beneath the underside of the drain rim.
This clear, white or colored caulking provides a seal between the tub and the drain, although regular use and excessive scrubbing may wear away at the material, making it necessary to recaulk the drain from time to time. Follow the manufacturer's instructions when applying a waterproof caulking to your plumbing fixtures. Although caulking directly around the bathtub drain can help eliminate water leaks, this type of seal won't help insulate your tub area from leaky air that enters through large gaps around the exterior sides of the drainage pipe.
Large gaps and openings in the underlying floor provide a common source of energy loss.Log in or Sign up. Gasket or putty under bathtub drain lip? Joined: Mar 21, Location: Virginia. I'm installing a new lift and turn bathtub drain.
The new drain is packaged with a rubber gasket, and the instructions seem to show that the gasket goes underneath the drain lip on top of the tub. The old drain had putty in that location. I've cleaned out all the old putty, and I found the ring and gasket underneath the tub intact. They seem salvageable. My question is about the gasket that came with the new drain. The local hardware store clerk said I didn't need putty under the new drain lip on top of the tub because "all the new stuff uses gaskets these days.
Or should I remove the gasket that comes with the new drain and use putty instead? Thanks for your help. PKMay 4, The seal on top of the tub is somewhat immaterial because it is just to make sure water stays in the tub when the plug is installed. The gasket under the tub is what is making sure water does not leak into the ceiling.
But if the gasket is used on top of the tub and is too thick it will create a "dam" around the drain and water will always stay there. Last edited: May 5, Thanks -- that makes sense. I'll use the gasket that came with the new drain to replace the old gasket under the tub, and I'll use putty on top of the tub.
There's a thin, stiff ring under the old gasket. What's it's purpose, and do I need to replace it as well? I don't have one lying around, so that would mean another trip to town.
PKMay 5, If so discard it because it can prevent the rubber gasket from sealing properly. Its only use would be to help assemble the drain assembly by screwing the shoe ONTO the strainer while holding the strainer stationary. Which is the opposite of what you are doing, or what any plumber would have done. You must log in or sign up to reply here.Nov 23, 1. Messages: 13, Likes Received: Nov 23, 2.

I never seen a foam gasket for the sink drain. But I haven't installed near as many as our resident plumber ol'Jim. I've always used putty and it's never failed me.
Nov 23, 7. DOH, for the drain use the putty, not the foam gasket. I always dope the threads on the under sink end and rubber that goes on the bottom too. I've had water trace the threads down and leak. I guess I'll hafta post that resume' pic again!! Nov 23, 8. Nov 23, 9.
How to Putty a Shower Drain
Messages: 2, Likes Received: 0. I recently replaced all my faucets in my house and used the plumbers putty and have not had any issues with them at all.
I even used plumbers putty when I installed a new garbage disposal in the kitchen and it worked great. Those supplied foam gaskets have a tendancy to age harden over time and start leaking. Do yourself a favor; toss those supplied gaskets and use the plumbers putty.

The drain is slightly recessed compared to the rest of the tub. Is it better to use Plumber's putty or silicone on the drain?? That tub is acrylic, right? Contact Kohler if you don't have their printed recommendations. The same one that I had with my documentation so the info they gave was no help at all. Before I retract that recommendation, I will just state what is known by many plumbers.
Plumber's putty can be used on numerous applications in relation to drain shoes, basket strainers. There are certain manufactures that recommend that you do NOT use putty due to either the physical properties of thier product, such as pourous type bowls or certain corian tops. Has to do with the putty staining the product it attaches to.
I use putty for the following: Cast Iron sinks or tubs Cast Iron pedestal or drop-in sinks Porcelain drop-in steel sinks Fiberglass tubs and showers Composite type sinks Stainless steel sinks Brass bar sinks. Since your unit is acrylic, it is worth calling Kohler as advised to get the final say in the decision of what to use.
I have used silicone on certain cast-iron Kohler sinks where I cannot get putty to work on sealing the strainers due to the degree of angle of opening where strainers go.
Post Edited - - - - - - Always be aware of cross-connections in your potable water systemsThey could one day harm you and your loved ones. Plumbers putty never drys. Silicone will dry at some point and will no longer move. Plumbers putty has the same consistancy long after it was installed.
Silicone is great for a flange to flange assembly that produces a very steady seal. If you put a "bead" of silicone on a table, and a similar bead of plumbers putty on the table. After about 12 hours you can pull the entire bead of silicone up as one piece, but not the putty.
Silicone will lose its seal on one side over time, putty will not. Unless your entire Waste and oveflow fitting is brass and your tub is mortared to the floor I woulnt even think of silicone. You have allowed to much flex. Plumbers putty is oiled based and could "possibly" stain acrylic, fiberglass or plastic products and definetely will bleed into marble or granite. It's always best to follow the manufacturers installation instructions whenever in doubt.
Most acrylic or gelcoat tubs or showers recommend to install the drain assembly according to the drain manufacturers recommendations. That is unless plumbers putty will cause damage to their unit, then you will see a warning notice with the tub documentation not to use plumbers putty. The specialty finish on some drain assemblies can also be damaged from being in contact with plumbers putty.

Author: Anonymous User just curious but does acrylic require some special precautions?The putty typically comes in small containers or tubs and is sold at home improvement stores.
The durable putty will not stain, crack, crumble or shrink. It should be used only in nonpressurized plumbing situations, such as draining, and never for water-supply lines. Place it on a flat, clean work surface such as a countertop. Turn the shower drain body upside down to expose its underside. Gently take the rope of putty and string it around this lip until the ends meet and form a circle. Press the putty joint together and work it until there is no visible seam.
Press the remaining putty gently against the underside of the drain body so it stays in place. Place the drain body into the tub opening with the thread side facing downward. Gently turn it clockwise to thread it into place. Insert the drain-body tool into the opening so that the prongs slip around the cross section of the drain body.
Continue tightening by hand until the face of the drain body is flush with the tub surface. Josh Arnold has been a residential and commercial carpenter for 15 years and likes to share his knowledge and experience through writing.

Tip If you removed an old drain body to replace the putty, clean the surfaces of both the tub and the drain body with a bristled brush to ensure that the new putty adheres correctly.
Warnings Seams in putty are weak points and cause leaks in the future. Don't use plumber's putty on plastic, marble, granite or any other dimensional stone. Use tile caulk or silicone sealant on these surfaces instead.

In places where the manufacturer does not supply a gasket and the flange is not metal they suggest silicone caulk. I've installed a couple of sink wastes with supplied foam washers that compress down to almost nothing.
They were very effective I first thoroughly cleaned the old putty completely away from the porcelain. I would not use putty. Be sure the bottom of the sink is clean and smooth. The rubber gasket should be sufficient to seal without putty.
Gasket or putty under bathtub drain lip?
The main reason for this is that the drain will sit slightly lower, hardly leaving a gap between top of the drain and sink. This allows the water to drain completely, instead of a small amount of water remaining around the drain seal. This way, in time, there will be no dry water stain around the drain seal. I would use a the rubber seal on top and the bottom if i had an extra. Put a little cooking oil on the rubber both sides to keep it bind free like an oil filter and torque down till the rubber starts to oval on the outside edge.
Yea, don't skip the putty, or something, on the sink parts I'm working on without the putty there is no seal. Never have, never will, by virtue of you being able to screw things together, they're not sealed tight. Sign up to join this community. The best answers are voted up and rise to the top.
