Same issue as always with bathroom exhaust and tissue paper test on meadow wing. Kurt in maintenance tried balancing and adjusting bypass between RTU return and exhausts in bathrooms. Core on ERV is plugged and I believe it may be collapsing internally on itself. I recommend replacing 1st with filters and see what happens rather than looking for a problem that may not exist. Communicate with Matt and Kurt when finished. Thanks Mark. See pictures of plugged Core in service titan. Also see pictures of exhaust fan they would like replaced. See pictures.cannot read information on tag. Try to look at plans at shop 1st.
