The system is working as planned. have recommended it to some neighbours as they all suffer post build leaks of one sort or another. After having three major leaks over a 12 year period, luckily when we were in the house. It is reassuring that there is a permanent watch on water flow proceedings. We were put onto you by our plumber. Who had fitted your system on some social homes to avert overflowing baths. It is good to see some original thinking on an old subject.
Long may you be “inventive”.
