The kitchen cast iron sewer pipe is leaking, and I want to replace the middle leak with a PVC pipe,

There are very, very many reasons why a kitchen drain pipe made of cast iron can leak if you want to switch to another PVC pipeThere are several issues to consider: whether the PVC pipe can be connected to the cast iron sewer pipe (the size should be selected), whether the PVC pipe has better performance than the cast iron pipe, and whether other materials can be considered to be connected to the cast iron sewer pipe.

PVC Pipe: Polyvinyl chloride chemical resin is the most important raw material, which is added with a certain amount of stabilizer, a little lubricant, a small part of the filler, a small part of the color agent, etc., extruded into shape by a plastic extruder (a tool) and injection molding by injection molding machine (special tool), and produced by cooling, curing, shaping, inspection, packaging and other processes. There are many sizes.

The difference between PVC pipe and cast iron pipe: PVC pipe has the advantages of light weight, excellent corrosion resistance, high mechanical strength, simple construction, and does not affect water quality; Cast iron pipes are susceptible to corrosion and affect water quality.

In short, the cast iron pipe is connected to the PVC pipe, and the process is more complicated, and it is very troublesome if you do it yourselfIt's best to find a professional team to deal with it This kind of water leakage problem is also responsible for the downstairs residents.

But to do these things, I personally think that it is better to find a professional company, because many times it is not professionals who are not careful enough when dealing with these aspects, and they do not cure the root cause. It is very likely that you will still be troubled by this kind of thing in the future. But when we invite a professional company to solve this kind of problem, we must also beware of being cheated.

After replacing the PVC pipe, you should also use a strap to wrap the joints of the pipe firmly, so that there will be no water leakage.

It can be sealed with a sealing strip, so that there will generally be no water leakage.

PVC pipes can be wrapped with raw tape or sealed with sealant.

The easiest way is to wrap it with waterproof tape after it is tightly installed.

The waterproof nature of the PVC material is very good, and as long as it is tied well, it will not leak.

Once the tube is attached, wrap it with raw material tape or seal it with sealant.

You can seal it with a sealed tube so that it doesn't leak and wraps it securely.
