Provent catch can leaking

[bazzaboy]

Has anyone else had a problem with the drain valve leaking, the one supplied with the Provent catch can? I fitted my unit about 2 months ago and have been checking it weekly to see how much oil collects. I went to check it again last week and found oil over various steering bits. I don't think it was a lot of oil, but as you know, a little goes a long way. After checking further I discovered that it was leaking through the valve.

To give them credit, I rang them up and explained the situation and they said they would replace the valve asap. Has anyone else had this happen and were they happy with the replacement, or did they replace it with a different valve.

Put some plumbers tape on the threads at the valve. Solved.
I went though the same saga.

Thanks Hodge, but my one's leaking through the valve. I tested it by putting some oil in the catch can and watched it leak out through the valve. A steady drip.

[Hodge]

Your valve comes apart yeah ? 2 parts joined by threads?
Sorry should have mentioned that'd where my oil leaked through.

Which valve are you talking about? Can you take a pic?

Ok this is the type of valve I got through Western filters Provent200 kit.
I initially thought the whole valve was "one" part. But the bit I circled in yellow where the hose attaches to actually screws out.
And the oil was leaking through the threads on that part.
If this is the same type of valve you have, this may be yours cause.

That part circled is an air fitting say for a rattle gun. Why have they given you this rsther than a proper barb fitting.

Yeah it's a fitting seen on air compressors. I think the valve it's self is some sort of an air valve too.
Just came part of a kit with the catch can. And it worked (except the leak).

Guys,
Mine is the same valve except it has a brass barbed fitting. The leak in mine is through the valve, as if it was turned on, but only a steady drip in the off position.

i did not get a valve with mine . i just went to bunnings and got a irrigation tap with barbs on it for about $2 . never leaked a drop in 3 years .

I think its becasue they use cheap chinee taps. You can get them for around 5 or so dollars. I have the same tap but it has two female threads. And I bought it from Pirtek from memory. Hasn't leaked a drop. I considered a Bunnings irrigation tap but being all plastic and my drain hose runs down and out at the rear section of the front guard and along the chassis rail for ease of draining, I was concerned it may get damage to easy. Hodge, its just a ball valve. Nothing really special about it....

Ive got the same valve and no issues with it been plastic. I used clear tubing and can easily see the amount of oil collecting in it.

This all I did works a treat

Garden hose connector and plastic tap

OK.
The replacement tap arrived from the supplier. Looks like the exact same unit. I have taped the threads and put a smear of industrial silicon on the barbs before tightening it all up. I'll be keeping an eye on it to see if this one leaks.

Provent valve? Didn't know they had one. Up to to run your own hose and drain tap.

A drain kit ( hose & drain valve/tap ) is an supply option when you purchase a Provent Catch Can.

Yeah, I seen those cheap-n-nasty kits on ebay. Provent don't make the kits, just sellers "Value Adding" (term used loosely).

I will use this one for a demo in FAIL: http://www.ebay.com.au/itm/Oil-Drain-Kit-for-Provent-200-/261831447404?hash=item3cf65ed36c:g:waYAAOSwYlJW3NX 8 (http://rover.ebay.com/rover/1/705-53470-19255-0/1?campid=5336709507&toolid=10001&mpre=http%3A%2F%2Fwww.ebay.com.au%2Fitm%2FOil-Drain-Kit-for-Provent-200-%2F261831447404%3Fhash%3Ditem3cf65ed36c%3Ag%3AwaYA AOSwYlJW3NX8)



PVC hose, does not work well with oil, goes hard and/brittle. Not good with heat either.
Ball valve, these have Teflon seals around the ball. Oil softens Teflon and and leaks will come of it.


Just my 2 cents.

OK ..... bugger!

Now the replacement valve is leaking. Same issue, slowly leaking through the valve, as though it was open slightly. Time for something new. Maybe I'll try the cheap Bunnings options. Something so simple is starting to annoying the crap out of me.

I have had this valve in for about 6 weeks and has not leaked a drip...

I have the same tap..
But mine is from a reputable supplier.
Been on 6 months and no issue yet..

[LostBenji]

Just get one designed for petroleum based oils.

Better tell the hydraulic world teflon is no good....
It is more than likely just a shit valve with shit tolerances

And look at the barb fitting they use on the end of the ball valve. It a Nitto male coupling for air tools. Lol. Get a decent ball valve, with actual barb fittings and some good hose with clamps and Bobs your aunty.
