Questions & Answers


Hi! Thank you for asking about the Liberty SJ10A. It is not recommended to use a ½” water feed line for operation of the SJ10. We have seen issues in the past with installations using ½” line not pumping properly due to not enough flow and pressure being supplied to the pump. It would be best if you could branch off of the ¾” line with a dedicated ¾” feed line for the SJ10. This should allow enough flow and pressure for the system to operate properly. Please don't hesitate to contact us if you have any further question or concern about this product. We thank you for choosing We are always happy to serve you!
