I've replaced the sanitary pipework under my kitchen sink, using a McAlpine 1-and-a-half bowl sink kit https://mcalpineplumbing.com/traps/sink-kits/bowl-and-a-half-sink-kit/
And a flexi connector to get down to the stub of pipe that drops into the zone under the base cabinet: https://mcalpineplumbing.com/plastic-chrome-fittings/flexible-fittings-non-return-valves/flexible-connector-universal-x-plain-spigot/
However, the sink now gurgles when draining. I think the fall of the flexi pipe after the trap is too steep, and this is syphoning the trap.
I want to avoid the trap drying out, and also avoid the annoying gurgling noises. So I'm considering lowering the trap and using straight pipe and a 90 degree elbow instead of of the flexi (red line on the photo).
Will this work to stop the syphoning? Or any other suggestions?
