After £200 per month water bills (family of 4 with 2 teenagers) I let this company that were recommended by United Utilities that do free checks for water saving come and check our house.
No leaks detected but, amongst a couple of other things, he replaced the shower head. I dunno the make and model but it uses less water. It feels really poor though, really doesn't satisfy like the old one did, and whistles as the water comes through the holes.
I am sold on the idea of getting an eco shower head to save on bills but is there one that doesn't feel pathetic. Budget £50 maybe more if it really is that good.
