I have an 8 battery roof solar heating system for my swimming pool which has suddenly has become completely blocked with no flow.
This may have been preceeded by the use of flocculant which then passed through my poorly maintained sand filiter, which in spite of repeated suctionng and backwashing, still resulted in a significant residue resettling in the pool
The sand has now been changed to a glass based material, and refiltration has completely stopped this problem- pool noe crystal clear.
I have now become aware of the possibility of "flocculant clumping", and wondered if a very large ammount of this clumped flocculant may have indeed been pumped up to and blocked the fine cappilary tubes in the solar panels.
Has anyone else heard of such a problem and what advice or suggestions are there to clear od dissolve these clumps?
Presumably they mainly consist aluminium sulphate combined with pool residue and proteinacious alge.
