We have a saniflo system in our loft bathroom. We believe we have drain flies in there (probably from not using the shower for a month or so as we were all using the one in our main bathroom). Does anyone have any advice on how to get rid of them as there is always standing water in the pipes? Is there a way to drain the pipes so that I could then 'fill' them with macerator cleaner in a hope that would kick the drain flies? Thank you
