Hi all..
We did a remodel last year and finally got the very large island done in March.. Anyway, it's got the proper drain vent for an island per drawings I've seen on this forum. So, my problem is that the hot/cold come down from the attic into the concrete floor and reappear under the island cabinet where they are terminated with your typical sink valves.. Now, I've got a KWC faucet that has water pressure which is <50% of what it should be.. I just disconnected the cold water supply line on the faucet and was able to fill a large vase quickly (great pressure -- what I expected) for about 2 seconds before I heard a WHAM and then the pressure dropped to about 50% of what it started out like.. I was easily able to repeat the problem.. If I closed the valve and started out slowly I could get the full pressure for as long as I wanted.. If I did a sudden open of the valve then I got the loud WHAM and the pressure drop..
Now, I looked under our other kitchen faucet (installed >15 years ago) and it's got a manifold of sorts for each of the supply lines with a vertical piece (perhaps 6" tall) with a cap on it aside from each valve.. I'm assuming this is working as a water hammer arrestor.
If I do something similar on the new island, will that solve the water pressure problem? I was the poor sucker that plumbed the faucet/drain on this after our plumber became a pain in the $#$#!@$ when it was time to hook up everything near the end of the remodel..
Any ideas on this would be greatly appreciated!
