Thread: Pressure Gauge keeps busting?

    Pressure Gauge keeps busting?

    Odd thing - last year the pressure gauge on the sand filter died on me (always showed the highest pressure reading, on or off). So I replaced it last year with a new one, and mid way through the year it died again. I could go out and get yet another gauge but is this indicative of another problem by chance?

    Also, the filter likes to spit sand into the pool, esp after a backwash. I've read this could be a busted lateral - is it dangerous to run the filter with busted laterals or is it just an annoyance?

    Cheers,

    Having the gauge fail every year is common. Failing mid-year is much less common. Still, those inexpensive gauges tend to break, so I don't consider it significant.

    Sand getting into the pool is only an annoyance, there aren't any safety issues I can think of.

    Is there any point in putting a super duper heavy duty industrial one on to replace the cheapies? If so, who has a source for a 'decent" one?

    Here's the one I bought. Great minds think alike!

    It's a compound gauge and it's liquid filled. I bought a bottom mount because it's self draining. I used a stainless steel street ell to mount it to the filter. I bought a compound gauge so I could check the suction pressure whenever I want or need to.
