Washing machine hose pipe smells

Anonymous user 03/03/2024 - 2.54 PM

Had originally two seperate traps from bowl and half sink and a seperate WM trap on the main waste which caused syphoning and led to smells from main waste. Changed this to single bowl and half waste with combined washing machine outlet. All was fine till recently smells from waste when washing machine drains. Have cleaned out washing machine hose pipe and all well for a while but still get smells which can only be coming from washing machine hose. The washing machine hose outlet is located above the water seal on the trap as is standard so how do I prevent these smells as there is no water seal to prevent the smells coming out of the hose and into the main sink waste. I have considered installing a separate trap on the main waste but before I do I would like some professional advice. Also should I install a Hepvo ????. No smells when washing machine not on. Have thoroughly cleaned out the WM hose of lime scale etc. Thanks This bowl and a half sink does not have an overflow
