Tankless Water Heater with PEX Piping System. For our house size and region a tankless system water heater would be extremely efficient compared to traditional water heater tank. This would reduce electrical use to heat water, deliver hot water on demand, and increase useable space in the storage area.
Press the pipe into the Shark Bite fitting until it reaches the marked depth on the pipe. If it does not reach the full depth, use the removal ring (an inexpensive, specialty item for Shark Bite fittings) to pull the line from the fitting. Ensure that the center, “inner pipe” inside the fitting is landing properly with the PEX line and reinsert the pine to depth. That’s all. It’s really that simple!
