Blue water from your tap?!

Have you ever had blue water coming out of your kitchen tap?

Although it is not recommended that blue toilet blocks be placed in the cistern, some people still do this. However, this practice has highlighted a problem that sometimes occurs if the w/c was incorrectly setup. If you’ve ever seen the above problem then it is likely that the inlet valve is not working correctly, the overflow pipe is set too low and there is a no air gap between the inlet valve CL mark & the overflow pipe.

Take a look at the link below to see if your loo is correctly setup (even if you haven’t seen any “blue water”)
