Shower Leak Repair, Replacement or Installation

Coming home from a day of work, enjoying a good bath forms a part of our lifestyle in Singapore.

Having problems for the Shower such as a leak or a slow dripping shower are definitely unwanted. If left unchecked shower leak can cause serious damage to your home. Water will have direct access to your membrane through cracked and missing tiles or grout of any kind, causing serious and costly damage. Do not underestimate a small crack for it can cause long-term damage and dampness throughout.

What causes a shower leak?

The majority of shower leaks in Singapore are caused by normal wear and tear, as well as natural shifting of a building. Water could leak through the bathroom tiles and drip into the walls, ceiling, and other sections of the house as a result of these shower leaks. Water damage from a shower leak can be significant, and shower leak repair is usually an expensive and time-consuming process.

Shower leaks can also occur when the shower head’s seals are broken. This results in water wastage and, in certain cases, water damage.

When shower materials, components and equipment are not aligned, it can too cause a shower leak. For example, if the shower joints are not properly tightened, the water pressure will cause the joints to loosen with time, resulting in a leak. Besides being aligned properly, it is important to ensure that the shower materials, components and equipment used are of good quality as well.

Lastly poor bathroom tile tiling can also result in a shower leak since water can seep through the misalignment and reach the other side, causing a leak. Even with a waterproofing agent, a shower leak is most likely to happen if there is a gap between the tiles.

4 Signs of a shower leak

If you suspect a leak in your shower now that you’ve learned about the various causes of a shower leak, keep an eye out for the following indicators of a shower leak:

  • Bad smell

If water has seeped beneath your tiles as a result of a shower leak, it can swell up the flooring and wall skirting, resulting in mouldy or damp-smelling patches on your bathroom walls and ceiling. If your home’s flooring is built of wood, and you notice a rotten odor in the air whenever you pass by a certain place near the shower, it could be an indication of leaking. This is because if there is a leak and water get into touch with wood, it will encourage the growth of wood-loving microorganisms, which will slowly destroy the wood and cause it to rot.

  • Bathroom wall damage

When there is a shower leak, the wall right behind the shower can be damaged. You can tell whether the paint on the wall is bubbling or peeling. If there are no paint-related indicators, you may notice damp stains on the wall.

  • Missing Grout

If you notice any grout missing in your shower, it could indicate that there is a shower leak. Grout is a mixture of water, cement, and sand that is used to fill the gaps between bathroom tiles. The grout will loosen if it is exposed to water on a regular basis. Even though the grout is exposed to water during showers, the contact is not continuous because it is on and off. Grouts will only come loose if they are constantly exposed to high levels of moisture and pressure.

  • Loosen Bathroom tiles

Constant exposure to moisture can cause the bathroom tiles to loosen, which can occur as a result of a shower leak loosening the grout that holds the bathroom tiles in place.

How to fix a shower leak

A shower leak can sometimes come from your bathroom’s shower unit like a shower head leak or a faucet leak, and these shower leaks are usually minor. Below is a useful guide should you want to try fix the shower leak yourself. Or you can always call us, Plumbing Hub if you need help.

Important note: Before you start, ensure that the water supply is being turned off so as to ensure that you can carry out the work at ease, without any sudden burst of water. Suggest that you prepare a towel just in case because there could still be water left in the pipe.

First, remove the shower head by unscrewing it from the pipe. You may want to use a pair of pillars or crescent wrench if it is too tight to unscrew with your hand. After removing the shower head, look inside for a little plastic washer or rubber O-ring hidden behind the threads. When if the washer or rubber O-ring appears to be worn or damaged, replace it with a new one. You can easily purchase washer or rubber O-ring in hardware stores.

After checking or replacing the components of the shower head, wrap up the thread on the pipe stem with a thin strip of tape around the threads at the very tip of the pipe stem. Hand-screw the shower head back on until you can no longer turn it. To give it a final tight turn, use a pair of pillars, but not too tight, since this could shatter the shower head. Turn on your water supply to let the shower run for a few seconds. Then switch it off and wait a few minutes to observe if any leaks or drips have appeared.

Open the faucet and let the leftover trapped water to drain. Next, you will need to remove the faucet as well as 1 or 2 valves and handles, depending on the type of faucet of your shower unit. 

A two-knob system is similar to a single-knob system, except that 1 extra component must be removed. To loosen the valves and remove the knobs/handles, use a screwdriver and crescent wrench. Remove the guards and you should see 2 nuts. To get to the shower stem, loosen the larger nut. Loosen the shower stem in an anti-clockwise direction to remove it. This shower stem works with a number of washers (such as Seat washers and Packing washers), all of which should be replaced to ensure that the current leak and any future leaks are being avoided.

Then reassemble the shower by first reattaching the shower stem, then screwing on the valves and reattaching the knobs. After that, connect the faucet faceplate and use caulk to seal the area where the plate meets the shower wall. Over the next few days, monitor to see whether any leaking has occurred.

If fixing the faucet does not stop the leak, you might want to consider replacing it. Shower faucets come in a variety of shapes and sizes, and not all of them are interchangeable. As a result, it’s critical to find the right replacement for your current faucet. Always take precise measurements of the holes in the faucet and bring your old faucet along with you when looking for a replacement. 

In order to bring the faucet to the hardware store, you need to remove it first. Begin by removing the faucet’s base. You can do this by loosening the nuts that hold it to the shower fixture using a pipe wrench. You can now remove the faucet’s base after loosening it. After receiving the new replacement, you will need to align the new faucet with the shower pipe and use a pipe wrench to secure it to the pipe. As previously mentioned, to secure the new faucet, always follow the manufacturer’s instructions. The water supply can then be turned back on to check for any leaks.
