Copper Pipes


The best material to replace lead is copper. Copper has been used to transport water for more than 4,000 years. 

Since it has been utilized in plumbing applications for so long, copper piping has established itself as the industry standard for rigid pipes. Copper plumbing pipes have been demonstrated to be remarkably resilient. The maximum pressure that this piping material can withstand is 1,000 psi.

Due to its corrosion resistance, dependability, and safety, copper has been utilized to distribute safe drinking water for thousands of years. Unlike other materials used for service lines, copper is extremely resistant, preventing outside contaminants from compromising the water system. 

Copper pipes are typically found as drain and vent lines. Soft or rigid copper pipes can produce solid connections and high corrosion resistance. Although it has a high corrosion resistance level, copper has become increasingly expensive.

Heating and HVAC systems also employ copper tubing most frequently as refrigerant lines. Choosing the appropriate copper pipe involves matching the pipe's wall thickness to the application's demands.

Copper can shatter, however, if the water inside the pipes is exposed to freezing conditions. The nature of the water passing through your plumbing system is the main reason for pinhole leaks. Below are the reasons for having a pinhole in your copper pipes:



Copper pipes may corrode over time if there is a lot of acidic water. Copper pipes can develop pinhole leaks when exposed to acidic or corrosive environments. 

Copper pipe corrosion can also be caused by water that is too basic or hard, which means having high concentrations of dissolved calcium and magnesium.

This implies that the breaches may be gradual yet persistent, making it challenging to detect if a leak is present.

Old Pipes


Additionally, the inner linings of copper pipes that are 20 years old or older typically grow worn and weaker with time. They are now more vulnerable to pinhole leaks, which can cause issues.

You can also use it on various materials, including copper, glass, plastics, and wood. You can use Flex Seal on painted surfaces as well.

Additionally, it can aid in weatherproofing and waterproofing your house. It helps seal cracks and holes in your copper pipes that are used for plumbing. Flex Seal can be used on both dry and wet surfaces as well as underwater.

Flex Seal performs best when the can is kept at an ambient temperature greater than 60 degrees Fahrenheit. Flex Seal sprays thicker than conventional spray paint, which is why it is effective.

How Do You Use Flex Seal On Copper Pipes?


You must take quick action if you see cracks or holes in your copper pipes. Pinhole leaks can become more extensive and eventually bust your pipes if they are not treated immediately. 

Flex Seal helps seal cracks and holes in your water pipes. Before using it, you should use an abrasive pad to clean the damaged area.

Gently apply a good coating using a brush to fill up all the cracks and holes. To preserve the freshness of the Flex Seal, don't forget to replace the can's lid. 

It slips into crevices and, after drying, creates a rubberized surface that seals off moisture, air, and water, preventing rust and corrosion. Additionally, it can aid in weatherproofing and waterproofing your house.

You can only use Flex Seal if the material you're working on is compatible with it. You can use Flex Seal on various surfaces such as copper, glass, wood, and plastic. 

Surfaces That Flex Seal Does Not Adhere To

Flex Seal Liquid does not affect silicone surfaces. You must remove silicone first before applying the product.

It's also not recommended to use Flex Seal on foams. Some foam may react when used with Flex Seal and warp or dissolve. We advise against utilizing it in environments with extreme heat or pressure, such as gas tanks or engine radiators.

How Long Does Flex Seal Last?

Flex Seal won't dry out, discolor, or deteriorate for up to 30 years. Proper upkeep and the surrounding environment will affect how long it will last. Flex Seal will be far more durable with a thicker coat than a thin one.

Can You Remove Flex Seal?

Liquid rubber, which is rugged and incredibly robust, is used to make Flex Seal. Once liquid rubber comes into contact with skin, it thickens into a complex, clingy substance that can be exceedingly challenging to remove. Fortunately, you'll be able to remove the flex feel off your skin, clothes, or other surfaces.

When removing Flex Seal, a bit extra caution is needed. First, use paper towels to wipe off as much of the product as possible. You may use warm water mixed with dish soap to remove the grime.

You may easily remove Flex Seal from the skin with steel wool. Give it a good scrub, and it will come off. 

Avoid applying too much pressure since it could hurt. The steel wool's grit must be coarse enough to remove the residue but delicate enough not to irritate the skin.

Flex Seal helps seal cracks and holes in your water pipes. The optimal surface temperatures for applying Flex Seal are between 0°F and 100°F.

Flex Seal can resist temperatures between -20°F and 140°F once it has thoroughly dried. Whatever the weather, Flex Seal keeps it together, whether it's scorching heat, torrential rain, or bitter cold.
