Bathroom faucet water leak - faulty faucet using both lines

[grall1126]

Hi,

I just placed a cheap Glacier Bay faucet, two handle into the sink. This is the problem.

I only have the hot water line hooked up on the faucet. I also have the cold water line from the faucet hooked up but not to the cold water supply. It's just hanging downward into a bucket. No cold water right now. Therefore, when I turn on the hot water, no water should be coming out of the cold water line. I have the cold water handle off but water still drips out. If I turn the cold water handle on - more water comes out.

It's like the hot water line is using both lines.

It seems to me that something is amiss inside the faucet?

What do you think?

Glacier Bay 217251 bath faucet out of home depot.

The water crosses over into the cold side from the hot.
You will need to either cap off the cold inlet to the faucet, or hook it up too.
The faucet somes with 1/2" straight threads, not tapered. A standard cap doesn't work well there.

Thanks Terry but I was wondering that shouldn't be normal for something like that. I thought when one line is closed off no water should be coming through? It looks like a few people have had the same problem with internal leaking in this faucet.

thanks

In theory, when you have the handle set to all hot, nothing should come out of the cold supply line (assuming it is unattached), but, depending on the cartridge design and quality, it can happen, as you're seeing. The only way to fix that is to cap it. One fairly easy way would be to put a valve on it - assuming you're going to eventually connect the cold supply, you'll need one anyways.

The cartridge MAY need pressure on it to seal.

Thanks for your replies, I am going to the store today and replace the cold water shut off valve so I can run the water. Hopefully this part comes of okay.
