Changing a Triton Shower Pressure Relief Valve or Device

Made this video primarily for my teenage son who's adapt at taking 30min showers and somehow triggering the PRV on our Triton shower. The symptoms of this problem are water gushing from the bottom of the shower unit rather than reaching the shower head. It is entirely a normal operation of your Triton unit designed to keep back pressure from damaging the pump and common causes can be a clogged Shower head or frequent "in operation" switching between normal shower head and rainfall shower head if fitted in your bathroom. The PRV is approx £3 from online stores like Amazon and Ebay - considerably less than a call-out charge or new Shower unit. Hope this helps someone 🙏
