i have installed a shower mixer on my bath. It leaks where the mixer is bolted to the underside of the bath on the HOT water side (from under the washer and nut securing it to the underside of the bath .)
Is this just because water is getitng past the mixer on the top of the bath?
Is there anyway a mixer could have an internal leak causing it to weep past the washer? or are the spindles welded onto the body of the mixer
