Answers

Why is the tank so heavy?
Thickness of the steel and the double-wall design cause the extra weight. The ENVIROSLIP uses 12 gauge steel for both the primary and secondary tanks in order to be extremely durable (something we feel is important to heavy industry). Heavier steel reduces the chance of tank splitting thereby increasing safety and environmental protection.

How is the visibility, because with my present tank I can’t even see out my back window?
The low 24” profile of the ENVIROSLIP 95 and 135-short provides increased rearview visiblity. This reduces the chance of missing (or hitting) something behind you.

During development it was brought to our attention that increased visibility was essential to make driving safer and we made this an essential design factor in many of our tanks.

What is that box on the top for?
The Fill-Spill box on top of the tank has two purposes.

First, fuel spillage is reduced when filling the ENVIROSLIP thanks to the Intake Spill Stop because it catches any residual drip.

Second, it is lockable in order to protect your fuel supply from theft and contamination.

What is that center vent for?
The vent found in the center is an Emergency Vent with a fusible plug. If there is rapid expansion due to heat or if the primary vent is unable to work, when parked on a side hill for example, the Emergency Vent ensures proper venting.

What is that pump mount for?
The Suction Tube with Emergency Valve combines a break-away pump mount with the suction tube and an emergency valve. The value in this design is simplicity. If your tank rolls over, the pump will break off and the emergency valve will minimize fuel loss.

What about cracking on the bottom?
Bottom plate welding has been minimized on the ENVIROSLIP. By bending the steel upward only the endplates need to be welded along the bottom. This decreases the amount of bottom cracking that can occur.

Why is it triple plated on the pump intake hole?
The triple plating on the pump intake is to maximize the strength around the intake that suffers the most from vibration and stress fracturing. This cracking will decrease due to the triple plate of steel surrounding the pump intake.

Will it fit in my truck and how much does it weigh?
An accurately measured tanks means less headaches when mounting into a pick-up. Using the listed dimensions, you can measure your box to see how your ENVIROSLIP will fit.

We do not take factory-sent steel and simply weld it together, but instead use CNC technology to cut and press our steel prior to welding. With our accurate measurements and market research we have designed our 135-short and 165 gallon tank to fit across any full-sized long box pick-up box while the 95 and 135-tall gallon model will fit inside the wheel wells of any full-sized short box pick-up.

For more information on which tank would best fit your tank, click on the make of truck and look up your model: GMC, Ford or Dodge.

How do you get into the secondary tank?
To do a quick check for accumulation use a dipstick and put it down the Dipstick Check (located below the Secondary Tank Vent). As a secondary method, remove the cap labelled “DO NOT FILL” (the Secondary Tank Vent Cap) and inspect the secondary tank.

Why should we use an ENVIROSLIP slip tank (IBC)?
If you are using a slip tank (IBC) that is ULC registered or is in compliance with the regulations, you do not need to replace your slip tank (IBC) until December 2009. However, even if you meet the requirement, there is good reason to purchase an ENVIROSLIP.

Cost of Inspections. The cost of doing an annual inspection can be high. More important to you will be the time of transporting and waiting for an inspection to be complete. If you use the ENVIROSLIP you will require an inspection every 60 months (after manufacturing date), saving you inspection fees and inpection time.

Tank Damage. If your tank is damaged, it will require costly repairs or may have to be replaced. If you are using the ENVIROSLIP double-wall design, damage to the secondary tank is acceptable as long as it does not damage the primary tank. This means that you will not have to replace or repair the tank when the inspection occurs.

Stewardship. If you are using anything less than ENVIROSLIP, can you truly say that you are exhibiting proper stewardship. The double-wall design and leading manufacturing processes prove that you are concerned and are doing everything you can to provide safety for the public and the environment.

When using ENVIROSLIP, you are showing co-workers, the public, your industry and consumers that safety and concern for the environment are your priorities.

Why are Enviroslip tanks more expensive than most competitors?

• Enviroslip only makes double walled tanks. You are, in fact, purchasing two tanks in one.
• Enviroslip tanks are like no others. The patented design includes 12 gauge P&O steel in both the inner and outer tanks and all critical surfaces such as corners and the bottom receive additional welds.
• All tanks have baffling in the primary tank to reduce sloshing and rocking.

Are single walled tanks still legal?
Operators are allowed to continue to use Non-Spec single walled tanks until January 1, 2010. However, all such tanks have to be tested and certified annually until January 1, 2010 when they become obsolete and must be taken off the road. The testing consists of 3 tests;

1. Pressure Test. The tank must be able to sustain 3 psi for 5 minutes.
2. Leak Test.
3. Visual Test. The tank is inspected for dents, rust, creases, etc. Regardless of the size of any of these blemishes, if any are found, the tank fails

What does Tank Testing cost and where can it be done?
Annual tests on non-spec tanks can cost a minimum of $95.00. There is also the cost of taking the tank to a certified testing facility or having a mobile service come to your location (down time). If the tank fails, you are still out the cost of the testing and the tank will be taken off the road.
Tanks that pass have a certificate attached to the tank. Failure to have this certificate in the event of a pull over by Transport Canada will result in a $1,000.00 fine.

There are currently very few Transport Canada certified tank testing facilities authorized. You may be in for a long search to find one.

Why purchase an Enviroslip Double Walled Tank?

• Enviroslip manufactures all the most popular sizes in double walled configurations; 95 gal., 135 gal., 165 gal., 488 gal., and 1000 gal.
• Enviroslip tanks do not have to be inspected for certification for 5 years from the date of manufacture. This alone will save the owner a minimum of 5 tests and $500.00 and they already comply with all 2010 Transport Canada and UN regs.
• Some large companies and insurance providers are beginning to insist on double wall construction. This feature is even being considered by ISO for their certification.
