Title: Garden tap with return valve.
Post by: Gordon_Taylor on March 31, 2009, 07:42:21 am

Hi all,

Would anyone know if using an outside tap with a non return valve would effect water pressure going into the ro.

Thanks

Gordon

It shouldn't do, unless it's a faulty non-return valve.

I also think that by law, all outside taps are sold with a non-return valve.

You should put one on if you haven't got one, by law.  That's why they're sold with one now.  Doesn't make any difference to flow/pressure.
