Hey everyone,
we recently bought a small house built in 1959. We have renovated it and have been living in it for some time now.
However, we have a problem. We renovated the two bathrooms located one above the other, and since then there has been an issue with the wastewater drainage. The entire vertical waste pipe is new (PVC), but it connects in the basement to the still existing old cast iron pipe. This means the last section, including the bend/angle leading to the sewer pipe, is still old. When we shower for a long time, the water does not drain properly at this point. It seems to me that the wastewater is standing there, draining very slowly, and leaking from the connections in the basement. A plumber has already been here and cleaned the entire drain pipe. Regarding the leaks, he said we would need to replace the last section as well. I had planned to do that, but only in summer (because of digging the pit etc.).
What worries me most, however, is that we apparently have no ventilation of the wastewater pipe. I haven’t seen any pipe going through the roof (as is usually the case). Was this common practice back in 1959? It shouldn’t be, right?
The gurgling sounds in the shower and sink are not too bad but are noticeable.
I’ve done some research and came across these air admittance valves (DN50). Would it help if I installed, for example, one air admittance valve under the kitchen sink and one under the walk-in shower (with the connection then leading to the basement)?
