Hello,
I installed a dishwasher in the kitchen of our student shared apartment yesterday, and now the water pressure in the kitchen is significantly lower.
I’ll just write down everything as accurately as I can - I’m not a professional, but I have read up a bit.
In the kitchen, we have a rather "old" mixer tap with 2 rotary valves (1x hot / 1x cold) and additionally a rotary valve for an appliance connection on the faucet (can be turned about 3/4).
From the angle valves on the wall, the two pipes go up to the mixer tap and from there one connection goes back down, with the 3/4 inch thread, to which I connected the water supply for the dishwasher. I installed the drain to the designated connection on the siphon.
To avoid flooding the kitchen, I closed the "main valves." I found 3 of these in the apartment. We have one bathroom and one guest toilet.
In the bathroom, there were main valves with connected meters for hot and cold. I closed those. And in the guest toilet, the same faucet again for cold water. I also closed that.
Before I connected the dishwasher, I also turned off the angle valves in the kitchen.
After connecting the dishwasher, I opened all the taps again - first the main valves, then the angle valves.
Since the dishwasher was bought used, I ran a test cycle right away yesterday evening. (First problem was that I didn’t know at which position the appliance valve on the mixer tap is “open.”)
In any case, everything worked fine and the dishwasher is running. It’s not leaking either.
However, I just turned on the kitchen tap and noticed that both cold and hot water barely flow anymore. There is practically no pressure; the water flows very slowly.
In the bathroom, there is full pressure!
So at first, I suspected the angle valves in the kitchen, but they are fully open.
So I thought of the main valves. I let the water run in the kitchen to determine which main valve controls what.
I found that the kitchen cold water is regulated in the guest toilet, while the hot water in the bathroom is regulated together with the cold water for the bathroom.
When I let the water run and opened and closed the main valves, very dirty (black) water suddenly came out of the tap in the kitchen and also from the shower, which I ran for control.
After 1 second, the water was clean again.
So; all valves are fully open, but still hardly any water reaches the kitchen - neither hot nor cold. Changing the appliance valve position didn’t help either.
Does anyone have an idea what it could be?
I’m grateful for any tip!
I am happy to upload pictures or further info!
Best regards and many thanks in advance,
Tom
