Plumbing Leak

After 7 plus years the sink faucet bit the biscuit, so it was replaced with a kitchen style faucet that came with 3/8" metal female connectors.  The original plumbing for the sink was a plastic 1/2" female connector.  Since I was unable to locate a 3/8" to 1/2" reducer bushing I had to get 2) 9" lines that went from a 3/8" female to 1/2" female and then get 2) 3/8" brass and 2) 1/2" brass bushings to connect everything together.  However where I go from 1/2" brass to the original 1/2" supply line I still am dripping water.  I pulled the plastic gasket out and it still feels quite soft, hence I am puzzled at to why it continues to leak.  At this point I may have to look for a brass 1/2" barbed fitting for the hose that has a 1/2" male opening on the other end or maybe discard the 1/2" brass bushing and replace with 1/2" plastic bushing.   Any thoughts on this?  Much appreciated.

	jato, I'm not sure what you mean by the hose? But if you mean the plumbing supply lines they are all I think 1/2 inch pex so you need to use pex fittings there. There are several vendors of various types, both push on, crimp, and clamp all readily available at your local hardware store. I personally like the stainless steel clamp fittings, changed all the old copper supply lines in my house over to pex last year and not one leak. But you need a clamp tool. If you just have the two to do you can buy the push on type.

	Thanks offgrid. Yes, I meant the 1/2' supply lines. Ended up getting 2) barbed brass fittings with 1/2" threaded male opening on the other end. Cut off the plastic pex fittings, ruined the rubber bushings when I screwed in the brass coupler, didn't have a replacement bushing even at the hardware store. After cutting off the pex fitting I installed the barbed piece with a hose clamp for both hot and cold, hooked up to sink, took maybe 5 minutes. Waited about 2 hours with pump on to check for leaks, there were none. Sounds like a very ambitious job to change the plumbing in your house, I can't imagine cutting so much drywall/plaster/paneling on the outer walls to accomplish the task! I installed the copper lines in my house when it was built in 1979, no leaks to date and I really like the heat transfer on the hot side. All cold side pipes were insulated with the blue styrofoam wrap to eliminate condensation in the basement area.

	Jato, glad you got it sorted out. Next time check out the Sharkbite type Pex push on fittings. I had to raise the house 9 ft higher due to chronic hurricane flooding here in the OBX. It is a 1930's house so all the old copper supply plumbing was shot. I installed a hot and cold water manifold (like a breaker panel for water) and ran separate pex hot and cold lines to each appliance/fixture. No tees or elbows. Its a single story house so once it was up in the air all the lines ran under the house through the floor joists prior to installing the new subfloor insulation and plywood underpinning. Very inexpensive, easy, and no leaks. Pex is great stuff, reduced freezing risk vs. copper because its flexible. It should last much longer than copper as long as it's not exposed to UV. I don't like the exposed hanging low point drains in the rPod for that reason. I covered mine with pipe insulation.
