Is It Normal To Have Standing Water in Your Shower Drain?

It can be concerning when your tenants start complaining about water lingering around their feet every time they shower. But is it normal to have standing water in your shower drain?

While this standing water isn’t ideal, it isn’t the end of the world, and understanding its causes and solutions can lead to a quick and easy fix. Whether you’re a seasoned property manager or a rookie landlord, gaining insights into this problem will help you maintain a smoothly functioning bathroom for your tenants.

This article will explore the causes of standing water in your shower drain, examine what it means for your plumbing system, and offer tips on tackling the issue.

How Shower Drain Systems Work

At its most basic level, your shower drain removes water from your shower basin and directs it into your home’s sewage system, but there’s a little more to it than that.

Basic Functionality

A shower drain consists of several vital components. The drain itself connects to a series of pipes that lead to your main sewer line.

One critical component is the P-trap, a U-shaped pipe below the drain. The P-trap holds a small amount of water, creating a seal that prevents sewer gases from coming back into your bathroom.

Along with the P-trap, vent pipes are essential as they allow air to enter the plumbing system. This air ensures water flows smoothly and prevents suction that can impede drainage.

Signs of Normal Operation

In a well-functioning shower drain, water should flow out quickly and smoothly, disappearing almost as soon as it hits the drain.

After turning off the shower, you might see a small amount of water in the drain, but it should quickly vanish. Typically, you shouldn’t notice any significant delay in water draining away.

If everything works correctly, the P-trap will maintain its water level, blocking any unpleasant odors from escaping while allowing wastewater to pass through efficiently.

Causes of Standing Water in Shower Drains

Standing water in your shower drain can be frustrating, but understanding the causes can help address the issue. Here are some common reasons why water might be pooling in your shower:

Hair and Soap Scum Buildup

One of the most frequent culprits is a combination of hair and soap scum. Hair can easily get tangled and trapped in the drain, and when combined with soap residue, it forms a sticky, clogging mass that slows down water flow.

Mineral Deposits from Hard Water

If your home has hard water, minerals like calcium and magnesium can build up inside your pipes over time. These mineral deposits reduce the diameter of the pipes, leading to slower drainage and standing water.

Foreign Objects or Debris

Sometimes, small objects like shampoo caps, razor covers, or bits of plastic can accidentally fall into the drain, creating a blockage. These foreign objects can obstruct water flow, causing it to back up.

Pipe Blockages Further Down the Line

Clogs can occur not just near the drain but further along in the plumbing system. Grease, food particles, and other debris can accumulate in the pipes, creating blockages that impede water flow from the shower drain.

Venting Issues Causing Slow Drainage

Proper venting is essential for drainage systems. Vent pipes allow air to enter the plumbing system, maintaining pressure and enabling water flow. If these vents are blocked or malfunctioning, they can cause slow drainage and standing water.

Problems with the Main Sewer Line

The issue may be more severe in some cases, involving the main sewer line. Tree roots, heavy grease buildup, or significant blockages can obstruct this pipe, leading to water backup in various drains throughout the house, including the shower.

Is Standing Water Normal?

Short-term standing water is usually not a cause for concern. For example, a small amount of water lingering for a minute or two after a shower is likely the result of a temporary minor blockage or the drain needing some time to clear the water. This scenario is normal and typically resolves on its own.

However, if you notice that water consistently takes a long time to drain or is persistently standing in the shower even hours after use, you could have a more significant issue. Persistent standing water is not normal and suggests a blockage or other problem in the plumbing system you’ll need to address.

Red Flags

Certain signs indicate standing water is a problem. When slow drainage becomes a regular occurrence, it’s a clear signal there’s a blockage or buildup. If unpleasant odors, gurgling noises, or water backing up into other drains accompany the standing water, you could have a severe plumbing issue to address.

Ignoring these issues can lead to significant problems, including water damage to your bathroom floor and subfloor, mold and mildew growth, and even structural damage. However, addressing persistent standing water can help prevent these costly and inconvenient problems.

Solutions for Standing Water in Shower Drains

If water is draining slowly or if you notice recurring issues, foul odors, or gurgling sounds, it’s time to call a plumber.

Professional plumbers have the tools and expertise to thoroughly clean and inspect your drain system. They can remove stubborn clogs, check for damage or blockages further down the pipes, and ensure your entire plumbing system functions correctly. Regular professional maintenance can prevent future issues and extend the life of your plumbing system.
