I think what improved in ours was the area of the shower spray, I know its not like the 20 litres a minute, that the home power showers are, but we get a lovely 3 to 5 minute shower. With a 15 minutes to fully reheat the water up again.We had the so called Ecocamel fitted and changed it within a week for a normal shower head. Now have a decent shower with a good flow. We would not have one of those Ecocamel shower heads in our caravan or at home. Goes to show how different we all are thank goodness. 😆
