When the old house was renovated for more than ten years, how about the cast iron sewer pipes in the

The cast iron sewer pipe of the old house, the entire three-dimensional layer is the same, if it is not uniformly replaced, the interface is problematic. In addition, cast iron pipes, both in terms of corrosion resistance and sound insulation, are quite good. If there are no major problems, it is also a good choice to continue using them.

It doesn't feel good, you can decorate the pipe.

When the old house was renovated more than ten years ago, the sewer pipes in the bathroom and kitchen were all cast iron sewer pipes, which may not be changed at this time, because it is the sewer pipe shared by the residents of each building and each floor cannot be changed, otherwise it will bear the corresponding responsibility.

Try not to use cast iron for the sewer pipe in the bathroom, we are doing sanitary partitions, that is, the partition on the public toilet, often seen more on the construction site, the sewer pipe is made of cast iron, the iron will rust after a long time, a place is rusty like a hose, and the iron pipe is rusted and cannot be repaired.

When the old house of more than ten years is renovated, what should I do if the foot sticker of the kitchen and bathroom is the sewer? If the old house is rebuilt, you must replace the cast iron sewer pipe in the kitchen and bathroom with plastic when decorating, and it must be a brand-name plastic pipe, so that you will have no worries in the future.

I think that since it is redecorating, it is best to replace the cast iron sewer pipe in the bathroom, otherwise it will be troublesome if there is a problem after the decoration. When the time comes, it's not easy to repair.

If it is an old-fashioned cast iron pipe, it is best to go to the local building materials market to buy the same style of cement adhesive fittings that can be cut directly with a cutting machine and connected to PVC.

Congestion and leakage sealing at the interface, use a PVC reducer to change the diameter, and the iron pipe is inserted into the reducer; The water pipe is the pipeline of water supply, and the modern decoration water pipe is built with buried wall, and the plastic pipe, such as PB and PP-R.

Remove the PVC pipe from the new one. But I'm afraid that the main pipes are all iron, so I have to discuss with the property, because the iron pipe and PVC are difficult to link, and there will definitely be problems in the future. Such an old house property should have been replaced with iron pipes long ago.

Exposed walls and floors are sawed off and replaced with ceramic or plastic.

As long as there is no leakage, wrap it up as it is now, and then do waterproofing and tiling.

It is possible to replace the PVC pipes that are now commonly used.

Cast iron sewer pipe is connected with PVC pipe:

1. Congestion leakage seal at the interface.

2. Use a PVC head to change the diameter, and the iron pipe is inserted into the reducer;

The water pipe is the pipeline of water supply, and the modern decoration water pipe is built with buried wall, and the plastic pipe, such as PB and PP-R.
