My son has moved house recently and the only place he can fit his dishwasher is a fair distance from the external wall of his kitchen.

I’ve fitted any number of washers/dishwashers over the years from scratch, but never one that would be so remote from a convenient waste outlet position and cold-water feed position.

I believe there are 3.5m Universal Drain Hoses (and universal 3.5m cold fill hoses) available for dishwashers.

I can take the cold-water feed from beneath his sink using the 3.5m hose which shouldn’t present much of a problem.

I can also presumably(???) connect the 3.5m drain hose to the ‘appliance U-trap’ beneath his sink.

His washing machine drain hose is already connected to the sink u-trap but I think there is enough room to replace the existing ‘appliance U-trap’ with one that has twin connectors for both washing machine and dishwasher.

I’d appreciate any advice as I’m a little reticent about fitting such a long (3.5m) dishwasher waste pipe.

Is it feasible?...any thoughts/advice/guidance etc gratefully received.

1. I'd run the cold water feed in copper, and properly clipped.
2. You can run the waste with a long hose, but you do run the risk of having water stagnating in the pipe. Make sure the waste pipe rises from the machine to just under work top level, then falls gently to the trap.
3. If you are replacing the trap, I'd recommend using a McAlpine. SK1 or SSK1 or alternative depending on type of sink.

Many thanks for the reply my friend;…the SSK1 certainly looks promising!(y)
 
Just give it a go and see how it all performs... as you're diy-ing, it's no great biggie if you have to return to make alterations - for us, we have to aim to get it right first time else it would be uneconomical... although "some" plumbers operate in this way :LOL:

Fair comment :mrgreen:;…you’re quite right, as a DIY’er I do have the luxury of a certain leeway with time/effort etc. However, as with my own profession, I absolutely hate re-visiting a project and ‘duplicating’ effort to get things working properly.

I work on the premise of ‘PPPPPP’;…however, as you pointed out, things don’t always go to plan :eek: ,…regardless of one’s chosen profession.
