How much sand does it take for a BaquaPure 22 gal. tank?

All air compressors have a water drain device on the bottom of the tank.
Get a wrench and remove this part. Shake all the sand out and maybe shoot some air up n there if you have canned air or another compressor to use.
Wrap the part with new teflon tape and reinstall it.

If you have a above ground pool go with the Cartridge or sand, and if underground go sand or D.E. All have their ups and down you should find out what you want from them specifically cause they all do varying amounts of the same thing.

Sand Filters (Filters using literally sand)
For sand filters, on inground pools, I like to use a 30 inch tank diameter, which is a 4.9 sq. ft. filter surface area, and holds 600 lbs of sand. For small pools (under 20,000 gals), I might advise the next size down (24 inch tank), if the budget is tight. But never go smaller than a this for an inground pool.
Cartridge Filters (like a air filter)
I have a rule of thumb for cartridge pool filters. 100 sq. ft. of filter surface area per 10,000 gals of pool water, as a minimum. I like to see the 400 sq. ft. models on inground pools above 25,000 gals. These can go an entire season without cleaning in most cases.
D.E. Filters (Ground up fossilized algae)
Because they offer the most superior type of filtration, people tend to go small with DE, and buy a 24 or 36 sq. ft. DE filter. Ugh - go Big! Nothing below a 48 sq. ft. filter, and if your pool is over 25,000 gals, go with the Big Boy - the 60 sq. ft. filter.

Also make sure the filter can take the amount of water that the pump is pushing through it.

for starters, a 22" filter should have been filled with roughly 300lbs of sand. this information will be found on the filter body and in the owners manual.

Fuel tank capacity for the standard wheel base Envoy/TB is 22 gal. and 25.5 gal. for the extended wheel base model.

The rear tank is rated 22 gallons, the side tank is rated 19.5 gallons (actual usable capacities are about 1/2 gallon less than posted capacity).
Please rate my help, thanks

If you have the standard wheelbase Envoy, you have an 18.7 US Gal. tank, if you have the XL model, it has a 22 US Gal. tank. Don't know off hand the conversion to liters.

There is a TSB on high sulfur fuel usage, and how it impacts the fuel level resistance.
If you change fuel, it might start working again. The TSB is : ERRATIC FUEL GAUGE OPERATION TSB 08-2-9

Publication Date: January 22, 2008
FORD: 2004-2008 F-150
LINCOLN: 2006-2008 Mark LT


ISSUE:
Some 2004-2008 F-150 and 2006-2008 Mark LT vehicles, built before 12/3/2007, may exhibit erratic fuel gauge operation or illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0460 or P0463, and/or Instrument Cluster Module DTC B1201. This may be caused by sulfur contamination in the fuel causing an open or high resistance in the fuel level sender.

ACTION:
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

Install a new fuel level sender following the service procedure instruction sheet provided in the fuel sender kit.

Should be 30 U.S. gal (25 imp gal; 110 L)as you have the higher end model. The lower end models have 22 U.S. gal (18 imp gal; 83 L)

it should be 18- 22 gallons depending on engine size and awd

if leak is around the top 7-way valve it is probably the rubber o-ring underneath that needs replacing. if the tank itself has a crack or hole you could try something like j/b weld to patch the hole.
