Hello! I just found this group in an attempt to help my DH troubleshoot our 2018 Reflection 312BHTS. We just got it back from an annual inspection from a GD approved shop and we are supposed to leave for our first camping trip Sunday. DH went to do the end of winter flush and fill and discovered that the pump is not functioning correctly. It just sputters and runs continuously without getting a normal flow to the faucets. He gave it plenty of time to bleed the air out of the lines. He hooked up to the city water and everything worked fine. I saw another thread on here from someone with a cracked pump casing and it sounded pretty similar. Hoping we can get our hands on a new filter quickly if that is indeed the problem. Has anyone else dealt with this problem? Really hoping this does not derail our first trip out as COVID really did a number on our plans last year.
