Drain UN-Blocker

[ETAF]

my son-in-law has a slightly slowly draining drain outside the house , which has the kitchen sink draining into.

when the water is flowing normally its fine, but empty a sink full of water and it overflows
its quite deep, so i can not get my hand down to clean out the "trap"
so i was going to try a good drain chemical cleaner

one shot has been advised from b&q , but when looking at the availability on stores it does not seem available - sulphuric acid
otherwise
caustic soda
BUT - i went to a few plumber shops saturday morning , and they can no longer sell any decent cleaner or acid. They can order in but only for account holders

any recommendations

Is there a manhole down stream if the drain? Get a man in to jet up from there if there is.

Thanks for the very quick reply
yes , but thats quite a distance to the manhole - we have one either side and at front of house - so maybe 5-6m away

we have a jet wash karcher

Get it jetted, I can jet up to 90m away.

The sale of high-strength acid drain cleaners to the general public has now been banned, in an effort to combat the instances of unsavoury characters throwing it in people's faces. If you really want some then eBay will come to your rescue (which rather makes a mockery of the new laws) but professional jetting is often the better option, especially on large bore pipes which won't be as thoroughly cleared by drain cleaner

You get a hose adapter for some Karcher models, I have one but not great to be honest, it does work to a fashion but takes a lot of faffing around

Chemicals aren't much use, often by the time they're where they need to be, the stuff is so dilute it's useless, or it simply melts a hole through the blockage, runs away and leaves the bulk behind. Mechanical methods are far superior, rods or jetting). If you can justify it, get one of these, https://www.wickes.co.uk/Wickes-Wet+Dry-Vacuum-with-Blower-20L---1250W/p/215735, may solve your issue, if it doesn't, it'll clean the gulley pot out enough to see what's going on.
