    Hi... my kingspan solar hot water system and range tribune unvented cylinder is making a weird groaning/jet engine noise when the system modvlvs pump is circulating, is this normal? .. any ideas what it could be or advice? Both getting serviced end of may and not noticed it until the sunny weather arrived. Thanks in advance. Ps tried to upload a video but failed.

    They work all year round so nothing to do with season

    Sounds like pump is stuck
