Aaaarghh..... whenever I run the bathroom sink tap water backs up into the bath. The bath is also very slow to drain. The toilet has also started making a whistling noise.
I have used every brand of drain unblocked and bags of soda crystals. I just bought some device but it is hopeless.
Any ideas (@pigletjohn) and others.
Really, really cannot afford a plumber at the moment. Was made redundant and have zero money.
Would be really grateful if anyone can help.
TIA
