Kwikot = Kwik excessive waterloss - watchout!

I reside in Vaalpark (Free State) I had a new geyser installed with a new kwikot pressure control valve recently. In the past the water loss over 24hr period minimal (max 1-2liters). After installation the 24hr water loss increased to 20liters+. Kwikot came around twice replacing cartridges, as well as 3 visits by AmandlaPlumbing (appointed by kwikot), with 24hr water loss still in excess of 10-12 liters! Discussions with Amandla (Johan & Corrie) revealed that water loss can by up to 10 liters per day, BUT mine is constantly 10 liters+. It would appear that they have given up and I sit with excessive water loss per day. Discussions with other plumbers indicated 1-2 liters per day loss, which is consistent with information on internet: https://www.housecheck.co.za/geyser-troubleshooting/ “anything more than a few litres a day usually indicates that the pressure control valve is faulty” https://www.property24.com/articles/avoid-the-geyser-nightmare/12495 “Anything more than a couple of litres per day often points to a faulty pressure control valve” I am contemplating my plumber re-installing the previous valve or a Cobra product, BUT WILL NEVER TOUCH KWIKOT PRODUCTS AGAIN!!!!
