Recommendation For Pool Maintenance Company/Person

[raysun]

If you mean the multi valve selecter which does filter backwash etc.  It depends on where it is leaking. If itsa crack somewhere on the main body  then get a new one, less than 90 euro and font almanzora will come and change it for you. Take a pic to them to explain.
they charge about 50 to fit but well worth the money.
There is also a gasket inside which  sometimes wear  and can cause problems  and when you take top off easy enough to replace.
But depends what you mean by a leak.
