Could do with a little bit of advice off any plumbers out there, or anyone with some know how. l have just bought and fixed a 'p' trap with washer and dishwasher connectors.The fixings fine and the two 135 degree bends on the inlet stalk are to both appliances.The dishwasher hose has a rubber collet on the end of the hose and this is pushed onto the bend and tightened with a clamp, no problem, no leaks.The washing machine has no rubber on the end of the hose, but is pushed onto the bend and again clamped with a jubilee clip but it leaks water when the washer is on.The clips are on really tight, so any ideas- and why wou;ld it still leak.
