Dishwasher hose - I am changing my kitchen and want the dishwasher further away from the drain and water pipe. Is it ok to extend the hoses (by adding another hose onto the current hoses) or do they need to be short for it to work correctly?

Check the inside diameter of the drain hose with a ruler.

Go to your hardware shop and tell them that you want two plastic inline connectors and 4 Jubilee clips for an inside diameter hose of ???

Get a one foot piece of clear plastic tubing from the same place.

Cut the hose in the middle insert one of the connectors and tighten it on with a clip put the plastic tubing on and tighten that

Put a clip on the plastic hose and fit the next connector tighten that up, now fit the original hose end and tighten the clip , job done

you can buy the drainage hose ( B&Q) by the per / m if you can not install a drainage pipe closer.

get another hose same diamiter and two hose clamps and a splice nipple from hardware store, cut hose to lenght with some extra insert nipple into both hoses and clamp with hose clamps make sure you get them tight.. use a metal nipple as a plastic one may crack when you clamp hoses
