Buster Bathroom Drain Unblocker 300ml, Pack of 2 – Sink Unblocker Removes Hair & Sludge in Showers, Baths & Sinks. Fast-Acting Shower Drain Unblocker Clears Blockages & Slow-Draining Water

Really good stuff sorted my blockage out

Unfortunately, not solve the issue. I consumed the full bottle in the sink and keep it all the night. And in the morning added boiled water but not worked.

The unblocker was purchased for use on my elderly mother's toilet. She wasn't aware it was actually blocked, until I found out whilst having a sneaky much needed pee. So I bought this (as it had good reviews), put a whole bottle down the loo and left it for 30 mins. On the bottle it says leave anywhere between 5 mins and overnight. The longer the better. Anyways...30 mins later. I poured some hot water down the bowl, as per the instructions and flushed. Glad to say that the loo contents went down the U-bend. Brilliant stuff. Highly recommended.

I have used this a few times in my toilet as I have to boys who like to over use toilet paper and the water doesn’t drain. Leave it over night and quick flush in the morning, seems effective.

I had a slow draining bath it took about 30 minutes to drain fully the shower also was slowly draining but on top of that my bathroom sink was just sitting with water in it all the time which needed scooping out. I bought this product not really having much hope and thought I must of have a major problem as all 3 were showing problems. I got this today and poured a full bottle in the bath plug and shared the other bottle with the sink and shower. I left it about 1 hour and pour kettle water in all plugs. I ran a bath as normal and when finished I drained it away and you could hear the water going down the pipes I tried the sink and that was draining away straight away. Cannot recommend this product enough it’s does exactly what it says it does and saved me 100s on a plumber :-)
