Hot-melt water pipes are all ppr, but can you use the joints of Wei Xing and other brands of water pipes (such as Jinde)? Will there be any problems in the future?

Not necessary, because the quality of different manufacturers and the sensitivity of products to heat are different.

Generally, the heat of a hot-melt machine is the same, so the melting degree of two different products is different, which will lead to the problem of incomplete fusion in future welding.

However, this situation is generally theoretical and there are not many problems.

If you use the second brand, you don't need to pay attention to any good brand, which is much more taboo. Ask the decorator specifically to make them understand.
