Ehup peeps . As per title , I have an elderly customer with a very slow running shower waste. Heres the best bit ... under a tiled floor and it even gets better ,theres electric UFH under that ..

Has anybody out there some miracle solution I can pour down the pipe.
Happy to try any suggestions

Thanks in advance
 
Dam Buster(s), basically the same as One Shot but better imho. Have used it on 1. 1/2 pipe full of hair and scum etc to great affect.
Don`t breathe in the fumes though.

Blocked bathroom drains are usually plug of hair+grease+soap.

A drain auger ('snake') is my weapon of choice with a plunger as runner up.

Chemical treatments are either strong acid (suphuric in the case of One Shot) or strong alkali (sodium hydroxide). I don't like either of them much because they are hazardous and less effective than physical means but in theory alkali works better for organic blockages such as:

There should be a special place in Hell reserved for bathroom fitters who install drains with incorrect falls and no access points.
 
Oh I dont half agree with your last paragraph @Chuck .

I read of a method years ago involving baking soda or bicarb and white vinegar , I may have a go but dont hold much hope . The customer wants me to try something on those lines first
 
Do you know if the waste pipe is a straight run ?

Could you feed a bit of 10mm bendy plastic down and have a poke ?

An educated guess is 2.5 m then 1 elbow and then around 3 m, it must all be level . They asked me about 5/6 years to do the bathroom, I was to busy , they went with a bathroom " firm" , the minute I walked in the bathroom after it was finished I said this day would come ... great

your best bet would be a snake if you dont want to go the road of chems
 
As me tupnęła earlier Oneshot is best thing in such situation BUT you will need to be careful as it's very accidic and it could cause damage to the the plastic pipe. However if you use a little and mix it with boiler water it will be fine. 99% I clear blockages with plunger and boiling hot water. I'd pour quite a few Liters of boiled water down the drain with a little one shot and then start plunging. You will see, it will solve a lot

Be careful using a plunger if there's any chance there are push fit or compression waste fittings involved. I've seen them blown apart by vigorous plunging.
 
I agree with rpm chems wont affect the pipe after all its stored in a plastic bottle. But after blockage is cleared the acid is flushed with water.

I have seen it few times, deformed pipes or eaten away which caused a hole. I only say that because of my experience.
However, I know for certain it will melt the pipes and can cause serious problems.

Not all plastics are the same though. Can you imagine a manufacturer being allowed to sell something that ultimately causes damage, respectively I suggest what matchless has seen is the result of two chemicals mixing.
 
Currently unable to edit the typo and my posts will include a time delay until cleared by a mod.

Would say there's more down to the boiling water your putting down the waste pipe
 
If hair is the problem, half a mug's worth of Oneshot will quickly burn through it and unblock the pipe. I have never had any damage caused by this product. The pipe can get hot because of the chemical reaction of the acid and water/hair in the pipe but I put some acid in the drain, (open windows for ventilatation, follow all instructions to the letter for safety) it burns through hair in only a minute or two then flush with cold water. Repeat as necessary until the water runs quickly, and completely from the shower waste.
