Washing Machine line

dnme

Hello folks,

Just moved into house after renovation. My plumber added the following lines into the utility for washing machine etc. Today, I went to use Washing Machine for the first time and discovered the line he connected to has no water. See first image. I checked the other lines and noticed they have pressure so to get out of a fix, I swapped over to the combo line (see second image). Is this OK, can it stay this way?

Why has the lever on the isolating valve been moved between the pictures ?

Just asking because as shown the valve is closed in the first picture and open in the second. Did you need to swap the valve too?

Just the way it was when I photographed it. I swapped the valve over as it was the only one I had.

But you can see the valve lever in opposite positions in the two pics.

Valve is closed in pic 1. It is open in pic 2.

That must have happened during the switchover.

Thanks.

If you have a tank of hot water, can you feel warm flow in the combo feed when you have water flowing from it?
It might be that only the hot water is available at this point and there's no cold in the combo either.

If you send the pictures to your plumber since its recent, you might get a very quick answer as there may be another isolation valve they can guide you to. The pipes are well marked and insulated, so I suspect they put a bit of thought into it.

When you say combo line, ,what do you mean?

Is this the rising main RM coming up through the red insulation

there could be an airlock in the one that failed, it should be back to the cold water tank so IFF you know what you are about, and IFF the combo is the RM, then feed the RM into the other blue one and give it a short blast to blow out any air

Combo = line on left where hot and cold are combined. I'm not sure why the plumber ran two sets of lines, any ideas? The way I have it now works, I ran the washing machine last night. I guess my question is, can I leave it like this? am I doing any harm?

I've never seen hot and cold combined like that.

Modern washing machines normally only have a cold feed - older ones used to have both a hot and cold inlet.

If your supply is warm, you may be wasting hot water for rinse cycles when only cold is needed. Also you might get hot water when you select a cold wash.

Without a TMV, this set up is at best wasteful as described by blackbox, and at worst dangerous
