Could find nothing in a search so asking about the best way to repair stock fitting leaks. This is at the hot water supply line connection for the kitchen faucet. The lowest drip is seen on the white connector (lowest point) but I'm not sure where the leak is. It is slow but enough to puddle overnight. I tried hand tightening the fitting. Should I use tools? I'm not wanting to replace stock plumbing lines with other materials. I appreciate the best approach.

Hot supply leaking at connection

I would not recommend using tools, those swivel fittings have rubber cone washers in them for seals. Over tightening may damage them. Is the leak really at the swivel to fitting joint. Or is water just appearing there and actually coming from someplace higher? Wrap a piece of paper towel around the braided hose to see if water may be tracking down them and then just dripping from the white swivel.
If the leak is actually where the hose is clamped to the swivel fitting, then that joint would need to be remade.Last edited by TedS; 03-04-2022, 08:25 AM.Ted

Hi Bill,
If the leak is indeed from the connection, it is relatively easy to take these fittings apart (by hand) and replace the cone seal inside. You might be able to buy just replacement seals, but if not, buy a similar fitting and use the seal from that. These parts are available at any plumbing store.
Those are the much discussed "soft hose" lines crimped to Pex fittings . . . the leak is most likely between the hose and the fitting. If this is the case, the best remedy is to make up an "adapter piece" to get the right barbed hose fitting into the hose and Pex pipe on to the Pex fitting.

I'll report the outcome.

Can someone let me know what size these connections are? Are they uniform throughout the unit? I likely have dodged a bullet not carrying extras.Bill & Cindy

BillinTexas the threaded connections should all be 1/2", the PEX is 1/2". The flexible hose is a tricky animal, I think the trade name is probably 1/2" but as Rob's photo shows it's a different diameter than the PEX and PEX fittings. I've been chasing a slow intermittent leak in my rig that I think I finally got, I replaced most of my flexible hose but left a couple pieces that were hard to get to and of course they were leaking. Even with the correct barb fitting and hose clamp the hot still had a slow small leak for only a couple hours every morning.

Hi Neil,
A fitting leak at a certain time each day is a curious thing. I was thinking pressure rise over night . . . but, you have a large accumulator tank which should keep pressure rise to a minimum. Hmmm .

Yeah. It was a hot line into a threaded tee that was coming from my hot PEX manifold, and going to the bathroom sink (PEX) and shower (flex). I replaced the line to the manifold with PEX and the leak has stopped.
It only leaked early in the morning, no relationship to shower time or bathroom use, my wife ran a couple back to back races last weekend and we were up early at about three am and there was no puddle (had an access in the coroplast open) but the 8 am there was a small puddle. By 9 or 10 the puddle was dry the rest of the day.
All I can figure is this: I've got a Truma tankless water heater, and it's got two modes. During the day I run it on comfort, where the heater basically keeps the water in a tighter temperature range, and raises the low set point when it runs the burner. At night just before bed I switch it to eco (mainly because it's quieter), which lowers the low temp set point to increase the time between cycles. I figure this change in temperature and pressure was causing the hose to expand and contract and leak.
Needles to say when we get home I'll be pulling out the last of the flex and replacing it all.Forum moderators are not GD employees--we are volunteers and owners presumably just like yourself.

Rob, looking at these photos closer, I have to ask why the need for a joint at the brass? It appears the crimp clamps are for PEX? Or am I just seeing this wrong? This link is for information and I haven't decided yet which I will buy. Are they different for the plastic tubing? Thanks for the information and education.

What Rob's picture shows is basically an "adapter". You get a 1/2" barb fitting with 1/2" threads and attach that to the flex with a hose clamp. Then thread that fitting into a female PEX connector which gets crimped onto a PEX line, which in his photo then has a 1/2" swivel female connector on it with the cone washer.
This should give you a proper seal at the flex hose, and end with the fitting you need to connect to your faucet lines.

Sorry if I'm doing a bad job explaining it, I'm not sure I was totally awake when I replied lol.

This is the set that I bought and it has served well Amazon.com: iCrimp Ratchet PEX Cinch Tool with Removing function for 3/8 to 1-inch Stainless Steel Clamps with 20PCS 1/2-inch and 10PCS 3/4-inch PEX Clamps and Pex Pipe Cutter- All in One : Everything Else
The cutter is small and very handy compared to the larger ones. The clamps for 1/2" pex do not fit the soft hose very well. I would recommend replacing the soft hose with pex but this may be a little more involved than you want to get. I have not found anything that joins the pex to soft hose very well, I did try one fitting from Lowes but it did not work and I ended up replace the soft hose with pex a much larger job but I ony had to do it once.
