Metal water features may have a stylish and simple appearance, but they are prone to common problems such as rust and corrosion, mineral and scale buildup, uneven water flow, and pump malfunctions. Proper water quality management and routine maintenance are crucial to mitigating these issues.

 

Metal water features are made from a variety of durable materials, including stainless steel, weathering steel, zinc, and aluminum. Each metal possesses unique aesthetic characteristics, ranging from a smooth, modern finish to a rustic, weathered patina, while also exhibiting excellent weather resistance. These metal water features can add a unique artistic touch to modern gardens.

 

Common Causes of Water Feature Failures

Have you ever passed by a once-pleasant metal fountain only to find it dry and silent? In short: it's usually due to a blockage, low water level, or an aging pump.

1. Clogs

Debris and algae can clog the pumps, filters, and nozzles of a metal water feature, affecting the normal water flow.

 

2. Electrical Problems

Power issues often cause steel fountains to stop operating. Pumps may wear out and stop working over time.

 

3. Water Level Issues

High temperatures and strong winds can cause water to evaporate quickly, causing the pump to run dry. Hidden leaks can also lower the water level.

 

4. Seasonal Factors

Extremely cold weather can cause pipes and pumps to crack. Strong sunlight accelerates water evaporation and promotes algae growth.

 

5. Neglected Maintenance

Irregular cleaning can lead to clogs and odors in the metal water feature. Ignoring small problems can result in serious damage.

How often should I change the water in the metal water feature?

Completely change the water in the metal water feature (corten steel, galvanized steel, aluminum, stainless steel) every 2 to 4 weeks. If the water is cloudy or in hot, sunny weather, more frequent changes are needed. Regularly topping up evaporated water and checking for debris ensures the water pump operates efficiently. Here are some simple steps to keep your water feature clean:

 

  • Every 3-5 days: Topping up evaporated water. The water pump must be completely submerged to prevent burnout.
  • Every 2-4 weeks: Thoroughly drain, flush, and refill with fresh water.
  • Every 1-3 months: Remove and thoroughly clean the water pump filter and inlet filter.

 

 

How to Keep Metal Water Features Clean

The key to keeping fountain water clear is removing algae. The following simple cleaning tips apply to steel garden bowls, ponds, and corten steel water features.

Simple Cleaning Steps

  1. Turn off your metal fountain and unplug it, then drain all the water. If possible, remove the water pump.
  2. Follow the product instructions to clean the water pump with a small brush and clean water to avoid damaging it.
  3. Mix equal parts vinegar and water in a spray bottle and spray it on areas where algae have grown. Do not spray near plants. Scrub with pure white vinegar, then rinse thoroughly.

 

Filter Maintenance

Clean the filter regularly to prevent clogging and bacterial growth. Clean or replace the filter as needed; consult the manufacturer's guide if in doubt.

 

Water Quality and Maintenance Tips

Change the water in your metal fountain every 2 to 4 weeks. For better cleaning results, use distilled water instead of tap water. Perform a deep cleaning once a year in the spring to maintain the water feature's good condition.
