new shower - trap not draining away

[cardenjw]

new marley low level trap on an elevated shower base. RA bend after 6" and a vertical drop to a RA bend then slow drop to 45 bend to t piece to main.

why will water not go away?

RA = knuckle bend or swept bend?

Can you remove the centre of the trap and re-try?

Are you saying that you have no flow and the water stays in the shower tray or that once the tray has emptied there is still water in the waste?

gents

RA - Knuckle bend

water not draining away at all or very very very very slowly -.......

trap removed and tried over a sink and OK!

think there seems to be a 'dip' in the pipe somewher and it its acting like a 2nd trap?????

if i blow down the pipe i get 'resistance' like i am blowing water.

must be a dip then......
