1. Where is the best location to install a Snyder Tank?
IMPORTANT: Prior to installing
any Snyder Septic, Cistern, Holding or Pump Tank, you must read and follow
the Document
"Site Selection/Preparation & Septic Do's & Don'ts". Failure
to comply with these instructions, will void the Snyder Warranty.

2. Why is it necessary to bed
the tank with sand/gravel?
Placing bedding in the bottom of the hole makes it easier to level the
tank and gives more even support to the ribs in the bottom of the tank. It
also keeps rocks or other sharp objects from damaging the tank.

3. Why must I fill the tank with water as it's
being backfilled?
Filling the tank with water adds enough weight to keep the tank from
shifting during backfill. It also equalizes the pressure between the
inside and outside of the tank, which prevents any distortion.
Please note, Snyder Rib Tank designs require filling with water as they
are being backfilled. For Snyder Low Profile tank designs, the use
of water during the backfill procedure is optional.

4. Can a septic tank be used for potable
water?
No. The pigments used in the septic tank are not approved by NSF for
potable water.

5. Can a cistern tank be
used as a septic tank?
Yes. The cistern tanks and the septic tanks are made from the same molds.
The cisterns are natural in color (no pigment) and are about 25% thicker.
The increased wall thickness is required to withstand the stress of being
constantly pumped empty.

6. How do I get my manhole
covers up to ground level when my tank is buried 24 inches below grade?
By using our manhole extensions (P/N 5160000W95301). They are twelve inches high and are
stackable up to three high.

7. How do I keep children
from accidentally getting into the tank?
You need to purchase our tamper resistant screw assembly which utilizes
pin-in-head Torx screws (P/N 34701197). The special driver is also provided.
top
8. Can I use a ribbed
septic tank or cistern above ground?
No. The ribs on these tanks are specifically designed to withstand the
stress from soil loading. Use of these tanks above ground could cause
deformation of the tank. We recommend using our more economical above
ground storage tanks that are specifically designed for that purpose.
top
9. What type of sealant
can be used to seal the manhole covers?
There are three recommended sealants: silicone, butyl rubber rope, and
asphalt. Silicone is the easiest and most widely used. Silicone is the
only sealant that should be used for potable water (cisterns.)
