Leaks Under Bathroom Sink

I had a leak under the bathroom sink. I attempted to tighten the fittings and the more I worked the more leaks I started. It's like the plumbing under there was done by monkeys. Anyone else have this issue? What did you do?

You gotta put your model in your signature line man. Nobody knows what you have just looking at your posts.

I can't be clicking on profiles! Put it in sig. Matter of fact, that should auto populate when you sign up for this site.

The monkeys that did my plumbing had an improperly calibrated PEX tool and all hose fittings in my wet bay began leaking, nearly simultaneously. A pic of your under sink fittings would help us help you.

2017 Vengeance 25V.

Pictures. Might as well took a picture of a baggy full of soggy spaghetti.

When I move one hose out ot the way to get to the leaking one, that begins to leak, etc. ....and yes, it's coming from the compression fittings.

For the money I have into this, the tow vehicle and work to fix it I could have invested that money and stayed in the finest of hotels.

Don't to this to yourself. If we do, we realize we could have stayed at 5 star hotels the rest of our lives, and still wouldn't break even! Those white hoses are exactly what leaked on my unit, but they didn't have the hand-thread fittings. They were clamped onto barbed fittings. I had to cut off the old clamps (used Dremel with cutting wheel, very carefully), then used PVC cutting tool to cut off ends deformed by old clamps, then had to buy a pex tool and proper size clamps to redo it all. No problems since.

Would Shark Bite fittings work? The one white hose leaks at the compression fitting. The blue cold water that it screws into is leaking on the bottom compression fitting. Think I might cut that "T" out and replace with Shark Bite "T" and find a new hose to replace the white one.

Lots of people use shark bite fittings to replace bad fittings on their RVs. One of the problems in your/my case, is they don't give you much slack on hoses, so when you cut bad part out, sometimes things barely reach when you put things back together.

I kind of figured that and thought I would buy some extra and splice it in. Actually I'm going to reroute the hot & cold to give me more room to work in there if I ever have to again.

Thanks.

You are on the right track. Over 10 years I have replaced every pex banded junction as in your pic with Sharkbite. For the non-pex tubing I bought the appropriate pex adapter for the transition.
When replacing joints, you are correct, there is rarely enough slack, so I just cut out ample old tubing and use couplings to add new pex if necessary.
I always carry extra pex, pex cutter, and Sharkbite fittings (couplings, tees, and elbows). Amazing how many times they get used by myself and friends on trips I have never had to replace a Sharkbite fitting unless I screwed up the install I have also successfully reused Sharkbite fittings when reconfiguring old plumbing jobs

The Sharkbite release tool can be very helpful (as can a Crescent wrench when you can't get your hands on the Sharkbite tool).

Exactly. And I have used both

Simple fixes are never simple for those who have never tried to fix it themselves. Go to Lowe’s and buy a PEX banding tool and bands… if that is the way you want to go.
I myself, I periodically check all the connections and joints. Always looking for that one thing that came loose from the last journey.
If you do decide on Shark Bite, do yourself a BIG favor and get the Shark Bite that was specifically designed for PEX!!! You will never regret it! ( Make sure you invest in the removal tools too, because you will always come up with a better idea “after the fact”!)

I’m a plumber and I deal with PEX on a daily basis. Those are a breed of PEX crimp I have never seen before. And I’m always checking out the latest and greatest stuff in trade magazines and supply houses. Those look similar to the type of ferrules used on hydraulic lines.

I canít believe Iíve never seen them before. They require a different crimper and look like they are very difficult to remove:

Well Earl,
I am not a fan of those braided lines, nor am I fan of the plastic fittings used with the PEX tubing in the construction of RVs today.

The braided lines swell with age and leak.

The plastic fittings crack and leak. They Are Not approved for use in residential or commercial construction for that very reason.

My solution will not be popular but it is to replace ALL of the braided lines that leak and the plastic fittings they are attached to with Brass fittings and crimped on PEX so it will NEVER leak.

At one point in my life I was a Journeyman Plumber so I have the tools, But a $10 pair of tubing cutters and a $35 crimping tool (at any big box store) and you too can do it easily enough.

IF you decide to do this buy the fittings at a Plumbing Supply store. They will be about 30% less than at the Big Box store.

Thanks for tip. I remember spending close to 100 bucks for an Irwin tool (calibratable)and a couple bags of clamps.

I've never seen them used on regular plumbing either. Only on A/C and transmission line fittings on vehicles.
