Hello,
this topic has already been discussed in the forum. However, I still cannot form a final opinion on it. Does a manifold system (MSH) really make sense or not? The alternative would be, for example, using PVC pipes in the basement, right? In the end, it all comes down to the same thing, or what is the added value of a manifold system? From there, the supply still needs to be distributed to the rest of the house anyway!?
Regards, SebastianH

How many houses, like the thousands that have been built, do you know where the KG pipe still does not fulfill its purpose today? Personally, due to my profession, I know of a high three-digit number of houses built within the last 4 years where a KG pipe has failed to serve its intended function. The reasons have already been mentioned here: radon, landfill gas, water...

The reasons have already been mentioned here: radon, landfill gas, water... Could you explain that? For example, I know radon can be present in drinking water, but the MSP (mechanical sealing system) doesn’t change that. Is it about preventing radon from the soil from entering the pipes? If so, how can this be resolved with an MSP differently than with a sealed PVC drainage pipe?

For example, I know radon can be present in drinking water. It can be. However, radon does not remain in water for long because it quickly escapes into the atmosphere. This is the key point: radon is a gas and can enter residential buildings through improperly constructed penetrations. Especially in southern Germany and the central mountain ranges, radon (more precisely, its decay products) can become a problem in poorly ventilated basement rooms.
Appropriate multi-utility solutions are proven to be both gas- and water-tight, even under external pressure. Any DIY solutions involving concreted-in wastewater pipes, subsequent use of expanding foams for construction and well sealing, or inserting ring space seals into underground drain pipes (for which, to my knowledge, ring space seals from Kr*** and Doy** are not specified) are not state-of-the-art or recognized technical standards.
