Are plastic or metal drains better?
When it comes to choosing between plastic and metal drains for your drainage system, both materials have advantages and disadvantages. Here we discuss the pros and cons of both so you can find the right drain to suit your needs.
Plastic Drains
Advantages:
– Unlike metal, plastic drains do not corrode.
– Generally, plastic drains are more affordable than metal ones.
– The smooth surface of plastic pipes reduces the likelihood of blockages, as waste is less likely to get caught inside and block the drain.
Disadvantages:
– Plastic drains are known to crack or break under heavy loads or in high-traffic areas.
– Over time, exposure to sunlight can change the colour and weaken plastic pipes.
– Plastic drains may not perform well in extreme temperatures or when the temperature changes quickly, as they can become brittle in cold weather and soften in high heat.
Metal Drains
Metal drains come in several types, each suited for different circumstances. Cast iron drains are highly durable and are often used in older buildings and high-traffic areas due to their strength. Stainless steel drains are more resistant to corrosion and are ideal for industrial and commercial settings, while galvanised steel offers added protection against rust, making it a common choice for outdoor use.
Advantages:
– Metal drains, particularly those made of cast iron or steel, are often incredibly strong and can withstand heavier loads.
– Metal drains typically last longer than plastic ones, especially when properly maintained.
– Metal pipes can handle extreme temperatures better than plastic.
Disadvantages:
– Depending on the type of metal, corrosion can be a significant issue, especially in environments with acidic water or soil. Regular CCTV surveys are essential to monitor for early signs of corrosion.
