Pst E7 100

[tc_rain]

I am looking at a PST E7 100 that I am told is new and has never been dove. There is a tank valve and boot installed and the visual inspection sticker that lists a date of 04. It looks like a bead finish and has the blue PST decal on the front of it. Should I be leery of it due to the expired vis 4 ½ years ago? This is being offered by a private party for $200. Anything special I should look for and is this a good deal or not?

Lots of things to go wrong on that kind of cylinder in that many years, especially if it's empty or been in salt water. Never trust what a seller says, or trust but verify if you wish.

At any rate, I'd take it to a good dive shop that knows how to do a proper visual inspection, ask to see training certs, and have them look it over before sending out for hydro if needed. Odds are that since the visual is that old the hydro is somewhere close by and needed as well.

If it's empty pull the valve off and look for pits of rust, or heavy rust in it. Pull the boots off and examine around them, look for bubbles on any stickers you see. Check the valve for a proper operation.

Basically look for rust/corrosion and if you see none or little then get it inspected/hydro'd. I'll let others comment on the good deal part, since it's probably going to need a hydro and vis the value is not nearly as high as it would have been with at least a couple years left on the hydro.

The date (month/year) of manufacture will be stamped into the cylinder. Does that match the vis year? This year I bought a AL-80 that was made in 01/95 and vis was 08/95 and a AL-19 that was made and vis in 5/05. Both cylinders looked brand new.

At min, pull the valve off and look inside. Also, tell him to hydro and vis the tank. If it passes you will pay for the tests. If the tank has not had a visual in 4-1/2 years the hydro has to be close.

Yes, the date of manufacture matches the vis year. He said it is brand new and has not been used.

That means nothing. If the first fill was wet it could be garbage now. If it sat empty with an open valve it could be garbage now as well. You've pretty much got to look at it to determine it's condition.

If it's clean it'd a good deal, and I would make the sale only on the condition it passes both the hydro and the visual inspection. Don't pull the valve if you're not serious about buying it, if you fail to buy it he'll have an empty cylinder that without a vis he can't fill to keep it clean. Only do it if you're serious and not just tire kicking.

If it's full drain the air very slowly as well, don't just open it wide.

I agree. Plus, if it's never been dove, and has been well cared for, the owner should have no problems agreeing to it having to pass hydro & a vis before the deal is done.

Too many threads about PST tanks failing hydro, so for it to be worth the price, it definitely need to pass hydro first. If it passes hydro, it's a great deal.

PST tanks falling hydros? Uh oh, kinda getting scared of my PST tanks now and they're doubles too.

Threre is a thread about 4 PST tanks failing hydro on The Deco Stop... it was their 1st hydro after purchase...

Only problem may be that when it passes hydro, it will be worth a bit more than $200 plus the cost of the hydro. If it were me, I'd pull the valve and give him $200 if it is clean (rust free) inside. Then find a hydro facility that has a good record with PST tanks and keep your fingers crossed. Or eliminate the risk and spend over $350 for a new HP100.
