Siphon issues - water does not drain

[bushidobrown]

Dear all,

I would like to consult with you, my situation is the following. Drainage in my kitchen has been extremely slow (water in sink stands for hours), I have bought and installed a new siphon and cleaned drainage pipes. The water still stands there and doesnt drain...can anyone advise what could be the issue? maybe not relevant, but a new apartment complex has been built right infront of mine recently...could this cause drainage issues? Or hydraulic pressure?

Many thanks for your replies

Best regards

Peter

Blockage further down the line. Lift manholes outside and have a look.
