I have a Hamat kitchen faucet which was in the house when we bought it 5 yrs. ago. It's made in Israel, is quite attractive, and works well with my kitchen sink layout. It's a single lever with side spray.

When we first moved in, the side spray didn't work at all and the water volume from the faucet wasn't very good. After trying a few different things that didn't help, I got a Hamat distributor to send me a replacement diverter, and installed it. Now the sprayer works, but half the water still comes out of the faucet when the sprayer is on, and the water volume from the faucet still isn't very good even when the sprayer is off.

Shouldn't the faucet stop when I use the sprayer? Is it possible I installed the diverter valve incorrectly? I haven't seen another faucet I like as well, but I'm getting tired of how long it takes to fill a pot with water.

TIA

Jo
