- less chance of leakages
- reduced risk of airlocks, corrosion and gunk as there is not a chance of air being drawn down into the system through open vents as the system is sealed
A pressure vessel is included in the system to deal with any pressure fluctuations in the water supply. Safety valves open if the inner pressure is too high. Other automated valves open to allow the inner water to be topped up if it drops to low.
