What is a basic but common reason for trap seal loss?

• Incorrect installation

• The seal water is leaking out

• Clogged pipes

• High water pressure

What could be the cause of the seal water leaking out, leading to trap seal loss?

• Rubber seals being watertight

• Plastic body of the trap being undamaged

• Rubber seals not being watertight

• Proper maintenance of the trap

Another possible reason for trap seal loss, besides the rubber seals not being watertight, is:

• The plastic body of the trap being damaged

• The trap being made of metal

• The trap being installed recently

• The use of high-quality sealant

What is a common reason for trap seal loss in warmer climates and holiday properties?

• Condensation

• Leakage

• Evaporation

• Overflow

What happens to the water in the trap of an appliance that is not used regularly?

• It gets contaminated

• It freezes

• It evaporates out

• It becomes acidic

How do appliances normally maintain the water level in the trap seal?

• By manual refilling

• By regular use

• By automatic pumping

• By absorbing moisture from the air

What causes wavering out, leading to trap seal loss?

• Changes in water temperature

• Wind passing over the top of a soil stack

• Poor installation of appliances

• Regular use of the appliances

What can assist with the problem of trap seal loss due to wavering out?

• A wind cowl

• A soil stack extension

• A water sealant

• Frequent maintenance

What causes compression in the soil stack, leading to trap seal loss?

• A) A long radius at the base of the stack

• B) A tight radius at the base of the stack

• C) Slow discharge of water from the WC

• D) Water flowing up the stack

What is the consequence of pressure building up in the soil stack due to a tight radius at the base?

• A) Water is filtered and cleaned

• B) Water is heated up

• C) Water is pushed out the lower traps

• D) Water is recycled back to the WC
