Here is the best advice I can give you about that Perflex filter and
Superpump. JUNK THEM. The perflex is hard to work on compaired to the
universal grid models, parts are beyond expensive an the filter is just not
that good. The Superpump does not compare with the Super II. The Super II
is just a better built pump. For a 28K inground pool and I hope who ever
built the pool was smart enough to put in two inch plumbing use a Hayward 60
sq ft DE or if you want to get away from the DE use a 400 to 550 sq ft
multicartridge filter. With the DE use a multiport valve because it is more
versatile and if you go with the cartridge filter you do not need a valve
because you do not backwash the cartridge filter. Use a 1 1/2 hp Super II
with either filter. Also you could go with a like type filter from Pentair
and use their Whisperflo pump. The cartridge filter from Pentair is called
Clean& Clear. The equipment from Pentair will be more expensive but it is
also better quality than the Hayward. If you are replacing the entire system
be prepaired to spend about $1500.00 including installation. If you can glue
PVC you can install it yourself. There is not much to installing the wiring
for a pump (is the system 220V ?). You can tell by looking at the breaker
(two breakers ganged together) and both leads to the pump will be the same
color with only the ground a different color. If you go with the
multicartridge filter get a replacement set of cartridges when you buy the
filter. When the first set gets dirty replace them with the second set and
get the system running again then wait until the first set drys and just
knock the dirt out or use some compressed air to blow the dirt out and they
are ready for use. Have fun.

Parts for bump filters are getting hard to come by and they are beyond
expensive. Junk it and get a universal grid DE filter (they have eight
curved grids and can be backwashed) and you will be happier.

Many years ago the bump filters were the norm but in the last 5-7 years the
back washable DE filters have taken over the market place to the piont that
most dealers do not even carry parts for them. If the dealers have parts it
may be because there are many bump filters in their area and when they are
gone they are gone. Besides with a bump filter you are knocking the DE off
of the tubes and allowing it to resettle back on. With the universal grid
style you backwash the filter and the dirt goes out with the water. It has
fewer parts and is much less expensive to maintain. Yes I agree that pool
parts are expensive but I feel replacing that filter with a newer one will be
more cost effective in the long run and also much less work for you.

The gauge is staying pressurized when the filter is off? I’d
replace it. Should only cost 10-15 bucks depending on the dealer.
The filter, ideally, should have a tight seal, where no air leaks in
when it’s shut off. When the pump is off, it creates something of a
vacuum which will try to draw air in. Upon restarting, if the
filter kicks right up, and no air is forced back into the pool -
then you have a solid setup. Some air is ok, just no long stream of
bubbles. Don’t overtighten bolts, as they may cut into the gaskets
you’ve replaced.
Unfortunately, it sounds like the previous owners didn’t do much to
keep their system functioning well.
I assume the DE is leaking back in for a short time after bumping,
eventually stopping? A hairline crack in the bump plate will allow
some DE to leak above the plate, which will get shot into the pool
upon restarting. The crack may re-seal itself once the plate is at
rest again, stopping the DE leak. Again though, it points towards
the plates. Although a small tear in the finger could cause this as
well.
The amount of DE recommended is normally correct, depending on your
pump. It’s considered optimal for filtering by the manufacturer.
I’d leave it at 6lbs for now, if not cut it back 1/2 lb. Some might
say it will reduce the amount of filtering that can be done, but
this is simply a marginal reduction, at best.
When adding DE, just scoop - dissolve - and add…don’t pack it in.
I’ve had customers just throw it into the skimmer and swirl it
around so that any chunks are dissolved before they get drawn into
the pump. I’ve also had them try to jam as much into a scoop as
possible… Use a bucket first if you choose to..it would work just
the same to dissolve the DE.
Per DE manufacturer and quality…it really doesn’t vary much. Any
foreign particles are likely the result of the manufacturing
process. I’ve rarely seen this in any brand of DE. I’ve used
Celatom before w/o problems. But then again, I’ve used others as
well.
Yes, parts are expensive - no matter what the brand name. But the
fact that they keep those on hand is a good sign. They’ve obviously
sold that brand for years - long enough to have customers come
looking for parts. That usually shows a good relationship between
the dealer and manufacturer (or at least their supplier). Trust on
both sides, so to speak.
Fleeting thought - when you drain/backwash, and replace DE, don’t
replace with all 6lbs. The only way to truely get all the DE out is
to crack the top open, and reclean the entire finger set.

producers of DE? Celatom, hth, AquaChem, etc. I did notice that
the AquaChem and hth have a very small amount of black granuals in
it that I didn’t notice in Celatom. Also, the Celatom appears to be
a brighter white.
…
pouring it slowly into the skimmer basket or just slowly adding the
DE dry into the skimmer basket? I’ve done it both ways. I think
mixing it first is the way to go. That’s how I became aware of the
black granuals because they settled out.
…
filter inlet just after the pump discharge outlet. The one that was
there was “shot” and “ripped”. Since fixing the air leaks and the
replacing the check valve, the filter holds it’s pressure even when
off. Should it do this? Is this a sign of a problem?
