Bad aerator threads on sink faucet


Hi;
I have a very old bathroom sink faucet. I wanted to replace the aerator. Sounds like a simple job, right?
Well, first off taking the old one out was a PITA. I had to use a vise-grip to unscrew it.

Now I have the new one, but I cannot get it to stop leaking, no matter what I do.
The faucet has female threads, so I am using the male threads on the aerator (which has dual threads - inside and outside)

I see what the problem is: The faucet's threads are bad. I took a photo using my phone's "selfie" camera and confirmed that fact.

I have tried wrapping teflon tape around the threads of the aerator before installing, but cannot get it to stop leaking. It leaks enough that water sprays out, or runs down the spout back towards the base and all over the place.

I Googled and found a thread in another forum where a guy successfully used pipe thread compound. But before I go spending more $$ on stuff like that, perhaps it is time for a new faucet. The only problem with replacing the entire fixture is that I am sure the old one is rusted in place. The faucet itself is plastic, but there are of course metal innards and bolts holding it to the sink.
I dread crawling under there, and cannot afford a plumber. That said, I do think I have a sink wrench...

So, just one last attempt to get this aerator to work without leaking... Is there anything else I can try?

Thanks for your help

FW

I agree with you, far easier to just replace faucet with another one.

I have very good results using pb blaster, basin wrench and tapping the nut to loosen up the gunk. Just my opinion.

Better than Liquid Wrench?

I don't have any proof that it's any better than liquid wrench. Imo, either one would do.

I think that PB Blaster is better than Liquid Wrench & better than WD40.

Re: Bad aerator threads on sink faucet


the threads are not the sealing factor for aerator.
the gasket is what makes the primary seal
& is most likely not tall/thick enough; that

or the damaged faucet threads are limiting the
ability of the aerator to tighten up onto seal...
you could try a thicker or 2nd seal in aerator?

Peace

I had that idea, so I tried a cut-down hose washer. It fit into the opening, but was too thick to allow the threads of the aerator to catch.
The faucet spout is plastic, and I know that the threads are damaged. I have given up trying for the time being, but may have another go at it tomorrow or next.

Is there anything besides the aerator I could screw into the faucet to attempt to clean out the threads? I used a 3/4" tubing brush, which did help somewhat.

A tap might work (tap & dye set) but it would still be easier & cheaper to replace a faucet or do what Bondo said. I'm in love with JB Weld too.

Re: Bad aerator threads on sink faucet


You can get a galvanized nipple of the same size and run it into the faucet threads to try and cut some new ones.

buy another multi thread aerator; it should have 2 seals inside
use any combination of these seals with existing seals to create a
thicker seal needed for installation; silicone grease all edges of seals

Peace

Re: Bad aerator threads on sink faucet


I would try JB Weld, but I won't be able to shut off the supply to the faucet long enough to allow it to dry. Too much use.

I think for now I'm just going to leave it without the aerator. It works well enough.

take all the guts out of the aerator & hand tighten body into threads...
this will at least corral/guide water down towards sink with a better pattern
