Tub Spout Leaking from Back – Here’s What You Need to Know!

Each of those problems, “tub spout leaking from back,” may seem minor initially, but when you don’t fix it right away, it might become a significant issue. In addition to being a major annoyance, it might be a huge infrastructure problem.

The most frequent causes and fixes for this issue are covered in depth in this comprehensive guide, which will additionally assist you in fixing it but also in preventing it in future instances.

How do Tub Spouts Work?

A tub spout has two purposes: it covers the tub’s water supply line in a beautiful manner and directs liquid out of the wall to prevent damage. You have a choice of at least two distinct types of tub spouts to place in the bathtub. Bathtub spouts with a diverter, and those without one are the two primary types.

Slip-in Faucet

Standard or half-inch pipes made of copper that protrude from the wall should be connected using a slip-in connector.


It features a nose attachment that attaches to a threaded area in the spout’s nose, which is where the water supply is supplied.

Switcher Spout

Diverter spouts come in a variety of styles that are suitable for two-in-one bathtubs and showers.

Diverter-less Spout

Those spouts have absolutely no diverter, as their name suggests.

Spout for a Brass Adapter

Such spouts can be constructed of plastic, zinc as well, and brass ducats.

What causes my Tub Spout Leaking from Back?

Tub spouts frequently have this issue, which is typically not the spout’s fault. This occurs because you very certainly forgot to clean the tube nipple during the installation on the spout.

This area has a great deal of granular buildups, which causes the joint to become loose. As a result, remove your faucet, wipe the pipe using steel wool, and finally, reinstall your spout by applying a small amount of caulk sealer.

Defective Seat Wiper

The seat washer, which is within the faucet, controls and releases the water anytime the water is turned on or off. Daily switching between positions causes friction degradation to the chair washer, which causes it to become stiff.

It is reasonable to state that the padding in the washer naturally experiences some tear and damage, which may result in leaks. Another possibility is that the seat washer’s rim will deteriorate.

Faucet Stems Components that are Corroded or Damaged

This issue may also be brought on by other faucet stem components that are blocked, cracked, or damaged. Each component of the faucet stem is vulnerable to deterioration over time, including corrosion as well as physical harm.

Diverter for the Tub’s Spout

A diverter’s primary function is to guide the flow of liquid from the faucet toward the showerhead.

Most tub spout components, however, are vulnerable to mineral accumulation and obstruction, which impairs their performance.

You will not be allowed to completely turn off the faucet’s water flow after taking a shower when the bathtub’s spout diverter is obstructed or jammed in some manner.

Due to this issue, water can leak not merely from the faucet but also from the tub’s rear spout.

Outdated or Broken Tub Spout

It could be advisable to get new tub faucets when you haven’t replaced your old ones in a while.

Occasionally nothing except completely replacing the entire tub spout can assist, regardless of whether you were to repair each component separately.

What to Do If the Tub Spout is Dripping from Behind?

Inspect the inside of the tube for cracks or obstructions before removing the spout to see what could be causing the water to pile up and shoot rearward. Additionally, inspect the remainder of the showerhead pipes and the water line that comes from the wall.

When there are gaps in the caulking surrounding the tub spout, rusted showering pipes may also cause water to flow into the walls and outside of them, giving the impression that the tub spout is leaky.

When debris clogs the tub spout’s entrance, water is forced back through the inner pipe, whether it is in the bathtub or is already there. Water may spill if there is adequate pressure.

How should the Problem be Fixed?

  1. Turn off your water source first. Avoid getting sprayed when repairing your spout.
  2. The spout should be taken out of the wall utilizing a wrench or tweezers. Take care not to harm the pipes that are behind it.
  3. Examine the spout for deterioration, such as rust or cracks. The complete spout should be replaced if you see any damage.
  4. Use pliers or a Phillips screwdriver to pry out the old washer off the interior of the spout, provided it is in excellent shape.
  5. Substitute the old screw with an alternative that fits tightly into the spout.
  6. When a rusty valve becomes the root of the problem, unscrew it with an actuator seat wrench and substitute it using another one.
  7. When you have to buy a new spout altogether, be sure to buy the right one for your company’s make and type.
  8. Replace any broken pieces before reattaching the spout onto the substrate and tightening it with a tool or pliers.
  9. Lastly, switch on the water source and check the spout to ensure it is operating properly.

A slip-on bathtub spout gets its name from the fact that it slides onto the waterpipe that extends out of the sidewall.

Below the spout, a single bolt is tightened. The newly installed spout should be carefully pushed onto the conduit till the rear of the spout hits the wall after the old spout has been withdrawn by loosening the setscrew located on the spout’s bottom.

Install it carefully to avoid damaging the wall tube or its inner component. To make sure there do not exist leaks after tightening the new setscrew, switch on the water supply. If not, caulk should be applied to the spout’s raised end.

You may need to replace the protruding piece of the wall pipe if the inner pipe turns out not to be a perfect match for the wall tube.

How Can a Tub Spout be Replaced

How Can a Tub Spout be Replaced?

The faucet spout needs to be taken out first. There are two types of spigots: setscrew spigots and thread-on spigots. It constitutes a setscrew spout because of a tiny hexagonal screw that is located beneath the spout.

To get rid of the spout, first, remove the screw by using a socket wrench or screwdriver. The tube will be exposed in this fashion, and in the event it is damaged, it might be the source of the leak. Remove any water from the conduit and clean away any leftover old sealing compound using a clean towel.

To make the sealing peeling process simpler, score it with a kitchen knife at the point wherein the bathtub walls and faucet meet.

Use a wrench to pry the pipe nipple out of the pipe. Plumber’s film or Teflon should be wrapped around the threads at both sides of the tip.

Insert the nipple onto the wall-mounted 90-degree elbow pipe. To make the tip tighter, turn it around.

The water supply spout should be reattached. To remove any debris, switch on the water supply. Fill the space behind the faucet spout as well as the wall with a fresh bead of sealant.

Put the spout back where it belongs and apply silicone sealant to cover the tube in order to stop any leaks at the connection.
