What methods do people use to drain a riser that is located in a basement?
We have a four-story building with the sprinkler riser in the basement. The basement consists of a small mechanical room and the rest is earth-filled. Would it be permitted to run a drain pipe up to the surface, which would drain the majority of the system until the water finds its level, and then provide a secondary 1" drain which would run to a sump pit? In this particular situation, the remaining water adds up to roughly 20 US gallons. The sump pit is 42 US gallons, and the sump pump is rated for 50 GPM. Thank you very much!

I have provide a drain collection system with a pump with discharge to the surface.

That is an acceptable means. The majority of the water just needs to discharged at grade level and the auxiliary portion can drain into the sump, and or mop sink. Preferably the drain should be located at or near the riser room. Sometimes during testing the secondary drain doesn't get flushed since it goes unnoticed.

Any technical solution is considered acceptable as long as you don't flood the basement.

Drain as much out the first floor if possible and then drain the lower portion to your sump as noted. 10/11/2021 04:42:12 am
The drain should ideally be located in or near the riser room. Occasionally, during testing, the secondary drain is not flushed because it goes unnoticed. Leave a Reply. |
