Below Ground Installation
The advantages of installing below ground include:
- Greater achievable flow rates on medium runs
- Longer single runs (up to 120 Metres from a single water source)
- Even greater water savings
- Lower susceptibility to ‘crusting’ of dissolved minerals from the water
- Less surface weed germination
- Ability to fertilise underground
The installation steps are similar to those for above ground. Set trench depth
according to soil type and plant needs. If plants are naturally shallow rooted
keep the depth to around 10cm. Keep trench relatively level without sharp
bumps or dips.
Installation Steps
1. Follow Steps 1 - 4 above.
2. When water flow through hose is established and it is clear that there is no
blockage, the hose may be covered.
3. After completing the first watering cycle, check water spread by digging into
the soil at varying distances. If only the trench area is wet the surrounding soil
is too dry to support capillary action, and the hose will need to be cycled until
the soil has been conditioned.
4. Accidental Damage. If the hose is subsequently damaged when tilling the
soil, this will show by a pronounced wet spot on the surface. To repair, dig
down to the hole, cut across the hole and insert a 13mm barb joiner.
