Simple Fixes for Common Plumbing Problems in Your Pool

Part of owning a pool or hot tub means taking care of any problems that might occur, preferably while it’s still early days and the problem is easy – and inexpensive – to fix. While some issues, such as chemical balance, are simple to understand and correct, dealing with plumbing problems confuses most people.

Plumbing issues in particular require swift action. Waiting leads to further damage and expensive repairs. While fixing a plumbing problem may seem daunting, there are simple solutions to common plumbing problems pool owners experience.

Air in the System

Any air in your pool system can be a serious issue, as it restricts water flow. This may cause cloudiness in the pool or even lead to the filter tank bursting due to pressure build-up, which may not be apparent when viewing the filter pressure gauge. One symptom of an air leak in your system is when streams of air bubbles come from the water inlets into the pool. There are a few things that might cause air to enter your system, all of which have a simple remedy.

Check the water level of the pool, as a low water level can cause the surface skimmer to pull in air. If low water is the only issue, refill the pool to the proper level. Speaking of the surface skimmer, another component to inspect is the skimmer weir. The weir is the “flapper door” inside to mouth of the skimmer. It’s purpose is to actually create the “skimming action” by free-floating on the uppermost surface of the pool water level. The weir can become faulty and stick in the mouth closed position, literally creating a dam effect inhibiting the flow of water.

Other common causes can be the circulation pump and valves, typically located on the suction side and in front of the pump. The circulation pump has a hair and lint strainer pot with a cover and gasket / o-ring. When the gasket o-ring becomes flattened or the cover becomes damaged (cracked or warped), it can break the airtight seal, allowing air to flow into your filtration system. For valves, a cover is sealed by a gasket or o-ring and may begin to leak, the lid can warp or crack and let in air.

To determine if the circulation pump or a valve is the culprit of your air leak, start up the system and relieve any existing air by opening up the air bleed valve on top of the filter tank. Once the gauge has achieved the expected pressure, turn off the system and watch the pump area. If there is a small spray of water in any of these areas, then you pinpointed the leak. From there, replace all necessary parts and remember that you should never let an air leak go unattended.

Dirt and Debris

Dirt and debris is at the forefront of every pool owner’s mind, though usually in the form of thinking about cleanliness and water chemistry. However, dirt and debris can enter the plumbing and cause problems for you and your pool. Debris entering the filtration system can cause clogs or even wedge itself in valves and covers, letting in air. If the filter or strainer is clogged with debris, clean the strainer, then backwash the filter or change the cartridge. Dirt and debris may also clog the skimmer line, so your pool filter fails to work properly. If this is the case, turn off the pool pump and (if possible) the power to the motor. Clear any existing debris from the basket and use a plumbing snake designed for the particular type of plumbing to remove the clog from the skimmer’s piping.

Changes in Filter Pressure

The filter in your pool or hot tub must work perfectly to ensure optimum water safety.  A change in filter pressure is a common problem that, luckily, has an easy fix. Decreases in filter pressure are usually caused by clogs, trapped air, or incorrect valve settings. This can be remedied by checking valve settings, clearing suction lines, or replacing damaged hardware. Increases in filter pressure are usually caused by something blocking the filter, such as debris or an algae bloom blocking inside the filter. This can be prevented with regular pool cleanings and consistently clearing your pool of algae.
