Things been clogged for ages, tried everything but nothing works. My pipes are old copper ones too so I can’t take them apart. It’s smelling too and it’s looking like I’ll have to call a plumber.
Can you get that gel that unclogs them? I think it's called Mr Muscle drain gel. It's in an orange bottle if you can get it? Ive poured that down mine before. It works best if you leave it over night. It even dissolves hair apparently.
