If the tee can’t be installed more than 1m below the waterline, or if it can only be installed above the waterline,
some installers will put in a perfectly sealing non-return on the solar line to stop the main filter pump de-priming.
Please be aware, this is a special valve with a polished ball and rubber seat, contact us at
you require it. A standard flap non-return will not suffice. Also note, such a system will need regular careful
maintenance of the solar and filter line non-returns. Any failures or even the smallest leaks in these non-returns, due
to twigs or grit getting into the rubber seal, will pass air and eventually de-prime pumps.

Installing the Tuffman Fine Strainer
The above scenario you will require the Tuffman fine to protect the non-
return from fine grit and twigs. Depending on the level of pool use and debris
in the pool the strainer may need to be cleaned regularly. Use a jet of water.
