J-B Water Weld on PVC Pipe: Does It Really Work?

Are you disappointed in using PVC cement to seal the PVC pipe leak? Wondering how good would be J-B Water Weld on PVC pipe? Here I’m going to put light on all those topics related to fixing irrigation pipes with J-B Water Weld.

What are PVC pipes used for?

Whether it is for the distribution of drinking water, drainage solution or fire sprinkler system, PVC pipes are the most convenient option to use. As it is durable, safe, sustainable, cost-efficient, and mostly recyclable, different piping applications take in this piping material. 

What is PVC material? PVC or Polyvinyl chloride- a human-made polymer solid is the world’s most exploited plastic. Being produced throughout a reaction of chemical synthesis, PVC material is used to produce different product forms such as water pipes, wastewater drains, and sewer etc. 

This versatile material can produce uPVC (rigid) or PVC (flexible) forms of equipment according to preferred sizes and shapes. For irrigation, sewage, and plumbing, PVC pipes are the most sustainable solution. 

However, leakage in the existing pipe is a common issue we face. The easiest way to repair the damage is to keep the leakage under control. And, generally, we use solvent cement and couplings to connect the pipes. But, if you don’t apply the right PVC cement, it can get deteriorated. 

On the other hand, using the wrong glue can eventually lead to deterioration and call for repair. Now, you must be wondering, will J-B Water Welding on PVC pipe be helpful or not. 

It is a great solution for Polyvinyl chloride material, whether they’ll get wet or are wet. 

Can I use J-B Weld on a PVC pipe?

Though your plumber won’t recommend you to use it to repair leakage, temporarily you can use this product to stop the leak with a J-B Water Weld. For blocking small leaks on PVC pipes, you can go for J-B Weld. 

But, it won’t bring a good result for polypropylene or polyethene plastics. You will find identical recycling codes on the bottom of any plastic item. 

How to make a water weld seal on PVC pipes using J-B Water Weld?

J-B Water Weld can seal leaks, patch cracks and holes in your PVC water pipes. It is ideal for setting up underwater. You can drill, tap, sand and paint, or file it after curing. 

How to prepare the plastic pipes before using J-B Weld on them? Whether you’re about to adhere one plastic pipe to another or repair a broken PVC component, Make sure the surfaces are clean, oil-residue and grease-free.

Use white vinegar or rubbing alcohol to wipe down the repairing area to remove any greasy films. 

To affix two smooth areas together, use medium-grit sandpaper to rough them up at first. Following this, with a dampened paper towel wipe them away. 

Now that both surfaces are prepared, let’s go to our next step- preparing the JB weld by mixing their components. To make the epoxy that adheres things together, jet the same amounts from two tubes onto a disposable material or paper plate. 

With the help of a plastic putty knife or toothpick mix up the substances and apply the mixture onto the area you need to bond. Press it together to fix it together. 

If it is a heavyweight or flat item, it may be enough to remain together as the weld cures. In other instances, it would be good to clamp or squeeze the bonded items to hold them jointly with rubber bands. 

The average set time of JB WaterWeld is about 4-6 hours and takes 15 to 24 hours to set hard. The off-white color cured WaterWeld is rated at a bendable solidity of 1300 PSI and able to tolerate up to 300 degrees Fahrenheit temperatures. 

So, the bottom line is J-B WaterWeld is ready to use a plastic product that is suitable to use on PVC pipes. The process is convenient to use. It works great to stop leakage. But, don’t forget to wash your hands well after working with it.
