Pedestal trap cleaning

Czhornet

Hi all,

A few of the wash hand sinks up stairs have gone very slow to drain lately, is there a handy way to clean thoroughly the tight/compact P-trap behind the pedestal? It has no access point in the middle only the 2 ends are open.
I can take it off but i still need to flush the sh1te out of the bends some how. Would prefer not to use chemicals if possible.

like the link below except it has no small access point on the top of the bend

Try boiling a kettle and pouring it directly down the drain from a height. No need to dissassemble anything and often works via a combination of heat and pressure.

Thanks Alun, Does it work on those compact u bends as well?

When you are using the plunger or pump, use a cork or a squash ball to seal the overflow hole up, it makes a big difference to the amount of pressure you can push and pull through the trap.
Hot water works best, not boiling just hot like 50-60°C

I don't have one like that on my sink, I use it mainly on the shower where I can't easily get to the trap even if I wanted to.

Like CJHaugehy says, use good hot water, not boiling, and fill another container with it. Suck up a plunger full and squirt down the plughole. You may have to do this several times before it has the desired effect.
