I have to make a revision to my Poseidon 3960. How much it concerns him or-ring there are no problems. I have to replace the valve and the small tablet of the safety valve because' the regulator has a loss from the first stadium. In Italy where I live a center reparations Poseidon and' very away from my country. Someone can to point out me a solution? There and' some retailer that sells on line parts of exchange Poseidon? Thanks of heart. Gianni
