How should sewage pipes be designed to prevent freezing?
Thread Content
For pipeline design, we are using a 25-inch pipe. In the past, water was drained once per hour, but freezing still occurred; this was due to the rebar in the house getting in the way. Therefore, it’s necessary to bend the pipe to maintain a certain degree of strength. My question is: is it best for sewage pipes to run vertically downward?
It is best if no material remains behind the valve.
Some insulation measures, such as rock wool, can also be added.
Try to avoid using bag-shaped pipes for waste discharge, use as few elbows as possible, and keep the pipes as short as feasible. In very cold areas, insulation and heat tracing need to be considered
