Rain Gutter Diverter: How to Clean and Maintain Easily

A rain diverter is a device that helps you collect and conserve rainwater from your roof by diverting it away from your foundation or into a rain barrel. A rain gutter diverter can provide many benefits for your home and the environment, such as preventing water damage, erosion, flooding, mold growth and saving water and money. However, to enjoy these benefits, you must regularly clean and maintain your diverter. Otherwise, it may get clogged, leak, or malfunction, causing more problems than solutions.

The Importance of Cleaning and Maintaining Your Diverter

Cleaning and maintaining your rain gutter diverters is important for several reasons:

  • It prevents clogs: Over time, debris such as leaves, twigs, dirt, and insects can accumulate in your rainwater diverter and block the water flow. This process can reduce the efficiency of your diverter and prevent it from collecting rainwater properly. It can also cause water to back up in your gutters and downspouts, leading to overflow and damage.
  • It prevents leaks: If your diverter is not properly sealed or fitted, water from the joints or cracks may leak. This water can waste water and cause damage to your roof, siding, foundation, or landscaping. It can also attract pests and insects that may nest in the moist areas.
  • It prevents malfunction: If your rainwater diverter has moving parts such as valves or switches, they may wear out or break over time due to corrosion or weathering. This can affect the performance of your diverter and cause it to fail when you need it most. It can also create safety hazards such as electrical shocks or fire.

How Often to Clean and Maintain Your Diverter


The frequency of cleaning and maintaining your rain diverter depends on several factors, such as:

The type of diverter: Different rain gutter diverters have different designs and features that may require more or less cleaning and maintenance. For example, a simple splash block may only need occasional rinsing, while a complex rain barrel diverter may need regular checking and adjusting.

The amount of rainfall: The more you receive in your area, the more often you need to clean and maintain your diverter. Rainwater can carry more debris and contaminants that can clog or damage your diverter. Increased water pressure and volume can also cause more wear and tear on your diverter.

The condition of your gutters: The condition of your gutters affects the condition of your rainwater diverter. If your gutters are dirty or damaged, they can transfer more debris and water to your diverter. They can also cause more strain on your diverter due to improper drainage or alignment.

Generally, you should clean and maintain your diverter at least twice a year: once in the spring and once in the fall. This will help you prepare your diverter for the rainy and winter seasons. However, you may need to clean and maintain your diverter more often if you notice any signs of clogging, leaking, or malfunctioning.

The Tools and Materials You Need for the Job

To clean and maintain your rain diverter effectively, you will need some tools and materials such as:

A ladder: You will need a sturdy ladder that can reach your roof safely. Ensure you follow the safety precautions when using a ladder, such as placing it on level ground, securing it firmly, and having someone hold it for you.

A bucket: You must collect the debris and water from your diverter. You can also use it to mix some cleaning solutions if needed.

A hose: You need a nozzle attachment to flush out your rainwater diverter with water. You can also rinse off any dirt or soap residue from your diverter.

A brush: You will need a brush with stiff bristles to scrub away any stubborn dirt or stains from your rainwater diverter. You can use a small hand brush or a large broom, depending on the size of your diverter.

A cloth: You will need a cloth or rag to remove excess water or moisture from your diverter. You can also use it to apply some lubricant or sealant if needed.

The Steps to Clean and Maintain Your Diverter


The steps to clean and maintain your diverter may vary depending on the type and model of your diverter, but here are some general guidelines that you can follow:

  • Step 1: Prepare your tools and materials. Gather your ladder, bucket, hose, brush, cloth, and cleaning solutions or lubricants. Wear gloves, goggles, and a mask to protect yourself from dust and debris.
  • Step 2: Remove any leaves, twigs, or other dirt from the gutter and the diverter. You can use your hands or a brush to scoop out the debris and put it in the bucket. You can also use a hose to spray the debris from the gutter and the diverter.
  • Step 3: Flush out your rain gutter diverters with water. You can use a hose with a nozzle attachment to spray water into the diverter and through the hose or pipe that connects to your rain barrel. This step will help remove any remaining dirt or sediment clogging or damaging your diverter.
  • Step 4: Remove any clogs from your rain gutter . If you notice that water is not flowing properly through your diverter or rain barrel, you may have a clog in your diverter, hose, or pipe. You can use a wire coat hanger or a plumber’s snake to poke through the clog and clear it out. You can also use a plunger or a vacuum to suck the clog.
  • Step 5: Check the drainage of your diverter. If you have a rain barrel diverter with a valve or switch that allows you to switch between diverting and draining modes, you must check if it is working properly. You can test it by turning on the valve or switch and observing if water flows into your rain barrel or back to your downspout. You may need to adjust or replace it if it does not work as expected.
  • Step 6: Check the slope of your rainwater diverter. If you have a splash block or a flexible extension that disperses water over a larger area, check if it is sloped properly. You want the water to flow away from your foundation and not pool around it. Adjust the slope by bending or moving the splash block or extension.
  • Step 7: Check the fasteners of your diverter. If you have a downspout filter or a rain barrel diverter that requires you to cut a section of your downspout and insert the diverter, you need to check if it is fastened securely. You can use screws, nuts, bolts, clamps, or zip ties to secure the diverter to the downspout. You can also use caulk or sealant to seal any gaps or cracks that may cause leaks.
  • Step 8: Clean the exterior of your rainwater diverter. You can use a cloth or rag to wipe off any excess water or moisture from your diverter. You can also use a brush or sponge, mild soap, and water to scrub off any dirt or stains from your diverter. Rinse any soap residue with water and dry off your diverter with a cloth.
