Replacing the seal should sort the leak. Fitting a shallow trap will likely cause other issues if the waste pipe goes into a soil stack.
The compression nuts holding the trap to the tailpiece and waste arm are designed to be hand tightened, and when you do it properly, the trap is watertight. When trap leak occurs, it's usually because the nuts aren't tight enough, the pipes are misaligned or the trap washer isn't seated correctly.
Removing the trap and replacing the seals
Clean all parts from the tailpiece down to the waste pipe. Remove the faulty rubber O ring and replace it with a new one. Reassemble the various parts and connect the waste back up to the base of the plug and the drain pipe.
Leaks from underneath the bathtub can be caused by issues around the waste pipe, overflow pipe, or P-trap, which are normally caused by wear and tear, poor connections, damage, or blockages.
Rubber washers might lead to a leak since rubber hardens and dries out over time. If your P trap's washers are hard or deteriorated, or if the washers have become misaligned over time, then they'll need to be replaced or realigned.
Attach the trap bend to the trap arm, using slip nuts and washers. The beveled side of the washers should face the trap bend. Tighten all the nuts with a pair of slip joint pliers. Never use Teflon tape on white plastic pipe threads and fittings.
Generally, the easiest and most effective sealant for leaking plastic pipes is a liquid pipe compound as they can create air-tight seals around a leak. In some cases, a silicone repair tape may be just as effective, provided the leak is small enough.
How to install a p-trap. Sink p-trap: Measure and cut the wall tube to the length needed. Insert the wall tube into the connector, making sure to use a slip joint washer to ensure a seal.
While other sealants can work, silicone's resistance to mould and durability in wet environments make it the preferred choice for most shower applications.
The Different Parts of Your Shower Drain's P-Trap
Although they look like the curved pipes under your sink, they are quite different in that they have a greater curve. Your shower's P-trap consists of three main parts: the inlet, water barrier, and outlet.
Leaking Water Pipe—Broken or loose pipes are a leading cause of shower leaks. If access is possible, take a look at the water valve behind the walls. Are the connecting pipes damaged?
100% silicone caulk is recommend. There are many conditions where plumbers putty could cause product failure and finished product staining, please refer to category #4 FAQs for these applications.
How to fix PVC pipe joint leak: Fast fix with epoxy! Once you've assessed the damage and decided to seal the leak, we recommend using Loctite Repair Putty-All Purpose.

Plumber's putty is a small but important product in the arsenal of any DIYer. You've seen it at hardware stores or in your friendly plumber's toolbox. If you have to stop or prevent leaks around your faucet, sink, or tub drains, plumber's putty is the product you need.
Yes, compound sticks, also known as repair sticks or epoxy sticks, can effectively and temporarily seal leaky pipes.

The most popular products for sealing kitchen sink drains are plumber's putty and silicone sealant. Both products create effective, waterproof seals, but we recommend opting for silicone. Silicone sealant is quick and easy to apply, and it's extremely durable. It's also much more versatile than plumber's putty.
The better substitute for plumber's tape (thread seal tape) is “pipe dope,” also known as pipe thread sealant or pipe joint compound. Thread paste is specifically designed to seal the threads of a pipe and is known to be better for maintaining a permanent steal than Teflon plumber's tape.
When Not to Use Plumber's (Teflon) Tape. Using plumber's tape on PVC, copper, or PEX pipe threading is usually not recommended. Those fittings often have a gasket or O-ring to create a seal between the two pipes. Also, avoid using this threading tape on fluid power (hydraulic) systems.
Wear and tear, including degraded seals and loose connections, are common leak culprits as well, not to mention corrosion in metal pipes and high-water pressure. These can weaken connections and cause leaks too. Clogs and blockages, as well as chemical exposure, can strain pipework and lead to leaks.
Flush Sink with Water Regularly
Especially during hot days, flushing your sink regularly with cold water can maintain the seal in your drain trap. Let some water run into your sink for five to ten minutes in the morning and at night to prevent complete evaporation.
Slowly pour about a gallon of water into the drain. This will refill the trap and recreate the seal to block sewer gases. For long-term prevention, consider adding a small amount of mineral oil on top of the water in the P-trap.
