Had new Trevi boost shower installed in December, water keeps stopping intermittently. Doesn't help turning temperature control. Could cut out valve be faulty?
Trevi Boost is designed for cold mains & hot gravity, is this how yours is installed ?, if it is then you may have blocked filters or a water supply problem, or the pressures are not within the Trevi boosts range, try National shower spares, www.showerspares.com or tel 0845 126 4141
