Just helping a friend Posted September 22, 2022 Report Share Posted September 22, 2022 Working on an older tub with a E2400-0300et low-flow heater that needs to be replaced. It has a tecmark pressure switch (3029_3010) on it. I would like to replace with a flow-through heater which are more available and less expensive. Can I do this with plumbing adapters and an in-line pressure switch? Quote Link to comment Share on other sites More sharing options...
