When purchasing a system, a lot of people do not consider the physical tank, and they should.
If we, the directors of Taylex, were looking to purchase a tank we would want one that was made out of one piece of concrete, i.e a monolithic structure and with the walls or chambers going all the way to the top of the tank… In other words a tank constructed like the ABS shell… the reason being…
Thousands of tanks have failed in Australia due to the poor design of the tank.
When you read the fine print on the warranty, you will find that in almost all cases the external part of the tank will have a fifteen year warranty (as per the Australian standard), but the internal baffles / walls do not.
These internal walls usually fail because they are made of fibreglass, or the concrete walls are siliconed, mortared or epoxied in.
This problem is so wide spread in our industry that some waste removal companies will make owners sign an “all care but no responsibility” waiver. This problem affects both plastic and concrete tanks and to replace a wall will cost thousands!!!
To our knowledge, Taylex has never had one of our monolithic tanks fail in the field. We have been building these tanks for more than 15 years. Our policy is “if one breaks on you, we will give you a new tank”.
No-one has ever taken us up on the offer – because we build ’em tough!
Some of the other common tank faults are.
- Chambers don’t go to the roof causing a cross contamination issue
- Walls are sealed with silicone, mortars, epoxies etc
- Fibreglass is used in internal parts of the tanks and after a time become brittle from the sewage.
- Plastic chambers are welded or bolted down.
