Jockey Pump on a Dry Pipe System 1

[sl3656]

Does a dry pipe system need a jockey pump? I am certain not, since there is no wet sprinkler pipe that needs pressure maintenance for small leaks etc. However, would appreciate any thoughts on this. Thanks.

Thanks all for the replies.

@SD2 - in my original post, I was asking whether a jockey pump, in addition to the main fire pump, was required upstream of the dry pipe valves. I do have a main fire pump to boost pressure from the fire service connection, as the pressure is insufficient. However, normally on wet systems, I have seen a jockey pump too, which serves to keep the main fire pump from starting automatically in the case of small leaks on the system side. Based on the replies I have received on this forum, it appears none is required, since the air compressor is serving this same purpose. However, I would like to know whether there is any harm in having one?
