my pool guy cleaned the filter and replaced the DE, but now my roof solar panels have started leaking. how do i stop the leak? does backwashing help in any way?
bypass the whole panel if you can ( one individual panel of several ) , or bypass that loop in that panel - car part rubber hose clamps
If you do not isolate the solar system when backwashing your filter, you WILL pump DE into the panels and plug them and destroy them. At this point you may have to disconnect the panels, wash them from the RETURN SIDE (from the higher pipe and HOPE that the DE will flow out of the panels... most likely your pool guy just screwed up your solar real good... if the DE is plugging your panels, when winter comes your panels will split because they are holding water and the freezing water will split them... I hope your pool guy has insurance
