Help with under bathroom sink pipe work

[Jhw2042]

But there is still a blockage in the pipe leading out of the wall but I can’t see anyway to undo this section. Please advise ASAP. Thank you.

That pipe is solvent welded, cannot undo.
Use a flexible drain cleaning wire.

Time to call in a plumber.

Get a wet vac in it or rig up something to reduce down and blown through or get a bike pump on.

some one quoted soda crystals in water in previous post ,don t know if that works or not,
if you go to a merchants and tell them your problem they will give you some thing to pour down the drain that will clear it,

I had this situation recently. I resolved it by cutting the pipe where it came outside and replaced the section. I used a push fit on the outside so if it happened again I had access from both ends.

Bear in mind if you cut the pipe you'll need a compression fitting to reconnect - as push fit waste tends to be a smaller diameter than solvent weld.

Where does it run to and how long is the pipe run

Call a plumber or you could rent a mini snake designed for bathroom and kitchens, and just snake the pipe from that opening as far as it goes. Might be messy, so consider that before you start.

Snake , wet vac , put it back together and plunger. Any of them three should work.
