Shower 'tray' seems to be made of concrete/terrazo. Looking underneath, the waste pipe appears to be solid (not plastic). Should I replace this with a modern waste pipe? My concern is that it may not cope with a lot of waste shower water and there is no trap.
Thoughts?
I have a basin making a 'gargling' noise. It looks like a 32mm (I think) S trap is fitted but space seems to be pretty tight under there. What's the best way to fit an air admittance valve?
I'm looking for a 'high output' (fed by unvented cylinder) mixer shower with a large shower head and wand.
Seems to be a massive range of price from from £100 to £1200.
So what's the difference between one of these:
