    This is what I used to replace my broken PSI gauge. It's been in operation for over 24 months and no problems. This is a great price for a liquid filled gauge. Direct replacement for the standard ones that last a season or so.

    I don't work for the company or anything like that but want to save you some money.
    They offer 15/30/60/100 PSI and up for $8.19.

    Hey, I got one of those. Of course it's on the hydraulic system on my tractor! I'm not sure my Sand Dollar would even stand enough pressure to move it off the peg!

    I have a -30" hg to 30 psig Wiki gauge on the pool filter. It looks just like the one pictured above except it's all stainless.

    HOT DOG!!! What a deal.
    Thanks for the find.
    Oil filled gauges are the best. They can last seemingly for an eternity.

    Is this the company you bought yours from? D they seem well built and is the company easy to do business with?

    I don't have a sand filter, but planning on getting one. Looks like a good time to secure a superiour gauge now, so I have it for next year.
    What pressure range should I get? Is 30 PSI too much, or is, say 20 PSi better? Don't want it so big that it's super low on the scale. HAHA

    Depends on your pump and setup. With my old pump, I was over 20psi. After installing a smaller 2 speed and replumbing the pad, I am now just under 20psi.

    I think a 30 psi should be a safe bet.

    Most pool pumps are capable of building a little less than 40 psig and since most systems run between 10 and 20 psig, a 30 psig gauge puts the operating pressure about in the middle which is where you want it to run.

    Re: Liquid filled pressure gauge! Inexpensive!!!! SALE $7.99

    Most stock gauges I believe are 0-60 psi that come with pool equipment, and the max pressure for the equipment is 50 psi typically. If your normally running below 20 I'd say a 30 psi gauge would work for you but you'd wouldn't know how max. your system went to if you exceed 30 psi. With that being said I've got the 0-30 PSI gauge and I'm happy with it but my pressure has never gone above 20 psi.

    I purchased my gauges from them and they shipped quickly. The liquid gauge will replace the gauge on cartridge/DE/sand filters with 1/4" NPT Lower Mount treads.

    Re: Liquid filled pressure gauge! Inexpensive!!!! SALE $7.99

    The specific one listed and linked has a number of copper alloy parts - is that OK with a pool? There was another option for an all stainless one - a little under 2x the money.

    My filter gauge today sits almost parallel to the ground - Hayward SP0714 valve. Does that mean I need a right angle adapter to have it sit vertical and is that important?

    Re: Liquid filled pressure gauge! Inexpensive!!!! SALE $7.99

    My 3 mo. old gauge is stuck on 20.. This is a real stupid question.. and I'm sorry. The gauge in the photo doesn't have the same numbers on the face of mine. If I bought a 60psi one, would it go from "0" to "60?"

    Is the 1/4 fitting what I need for a DE Pentair?

    Thanks in advance!

    This is the description of the gauge:Pressure Gauge - 2 in. - 0-60 psi, 1/4 in. Bottom Mount - Plastic Case

    Yes you need 1/4 in fitting. Here's the one you need. It's on the link on the first message:

    Decided I would like to get one of these for my filter. But they add nearly $12 for shipping ONE gauge? I suppose I'll see what's available locally first.

    Try Amazon.. I didn't find any 2" gauges... just the 2-1/2" ones. Good luck!

    I just ordered three gauges and the shipping was $9.19 total using the USPS option. The price of them has gone up a little but the shipping was reasonable. $36 including shipping for three gauges of my choice is a great deal.

    Choose the USPS Priority Mail option, it was the default when I checked just now. Shipping price for 1 gauge is $6.77, so that makes it about a $15 gauge. Not bad.

    See below for some more gauge options and my ultimate choice. Will report back on it when I get it and put it in use on my as yet to be purchased sand filter. HA

    UWV, Interesting question. At 1st, I thought to myself, OK.. the internals of the gauge will never touch the pool water. Well, after looking it up, that's sort of true. As originally thought, the gears, needle, pivots, etc.. will never touch the pool water. They're permanently suspended in the oil for lubrication and anti-shock against pressure surges causing sudden and abrupt needle movement. Like when you fire up the system, or shut it down, or get a clog when using the vacuum, even a brief clog, etc..

    Then I got to looking at how it's designed. I know what a manometer is, pronounced (mah-nom-eh-ter) the 'a' like in "ma" for 'mom'. Pretty cool invention, I have studied it a bit in the past. Ever heard of a sphygmomanometer? That's a stethoscope. Sphyg comes from sphygmos (Greek), which means "pulse". It literally means "to measure your pulse". Laennec (pron. like it's spelled, or Leinek) the father of thoracic medicine, was a genius!!
    Ooops, off track.

    OK, so a Bourdon tube, another French scientist, converts pressure into displacement and as it travels into the copper tube, it literally bends the tube as the pressure restores the tube's round shape from its flattened state, thereby moving the needle via a cantilever at the end of the tube. NEAT!!

    The pool water, or whatever other fluid you'd hook the gauge up to, does enter that copper Bourdon tube. But I imagine that once it's in there, it stays until you shut the system off. So if you do this, say 1x/day, your getting something like a ml or 2 of "copper infused water" back into your pool. I'm not sure how big the tube is in the unit. I wouldn't think it'd be an issue, as I'm sure Chem Geek would say it's so little it's not even there.

    I'd be more concerned with the fact that chlorine is corrosive to copper. Not sure how long it'll take to break down. I imagine the movement would die, or the tube would break before the copper got destroyed.
    Here's a cool drawing showing the tube & how it works.


    The only other option would be a bellows or diaphragm based gauge.

    Here's a center back mount 1/4" (bottom avail.), all stainless wetted parts, 30psi 2" gauge. Has a whopping 5yr. warranty and a restricted orifice to reduce pulsations and wear on the gauge internals.
    http://www.amazon.com/dp/B0087UPTGK/ref=biss_dp_t_asn
    It's about $23 /w free frt.

    It looks like most of these gauges use "phosphor bronze" as the material for the Bourdon tube. Which is mostly copper, but...
    Wikipedia shows the following:
    "....used in situations where resistance to fatigue, wear and chemical corrosion are required (e.g., a ship's propellers in a marine environment)."
    So maybe it's all good in the end.
    Then again, I looked at a chemical compatibility chart, according to that, both brass & copper show the following compatibility ratings.
    Sodium hypochlorite <20%, sodium chloride, salt water, chlorine water = Severe Effect, not recommended for ANY use.
    Stainless steel both 308 & 316 for chlorine water = Fair -- Moderate Effect, not recommended for continuous use. Softening, loss of strength, swelling may occur.
    I'm all but certain that our "chlorine water" & theirs are 2 different things. HAHA

    Having looked at gauges on Amazon and already having looked on websites elsewhere, seeing crazy high prices on these. I have decided I'm going to go with this one.
    http://www.amazon.com/dp/B0087USYQ2/ref=biss_dp_t_asn
    It's actually cheaper than a single gauge (includes freight) from the OP's linked vendor & it's even better quality.
    It has the brass internals spoken of in the previous paragraph and it has a 5yr warranty. That says a lot to me, but not always indicative of product reliability. This is an industrial brand and not a "value oriented product", so it appeals to me, a step up if you will.
    It can handle up to approx. 50psi working pressure before it breaks and a 25% surge, so 37psi.
    Pretty cool!!
