Rain Hose Irrigation System
Rain hose irrigation system with laser punched holes is an affordable irrigation system for overhead irrigation. Rain hose irrigation system uses nano technology to convey water to the plant. It has a series of holes spaced at intervals which sprays water flow by gravity, or from a water pump is initiated. Our 0.5mm thick rain hose pipes […]
How To Install Rain Hose Kits
Grekkon Limited’s manual on how to install rain hose kits in Kenya is an easy to read step by step guide. It details every aspect of rain pipe assembly in the farm to provide understanding to farmers. As the pioneer of rain hose kits in Kenya, we are keen to that farmers receive the full benefit of rain pipe irrigation. Rain hose pipes work under high gravity pressure (from 6M or 0.6bar), and with high volume water pumps. The discharge rate of the water pump is from 40 cubic litres per hour. These water pumps are surface solar, electric, petrol or diesel powered
How To Install Rain Hose Kits
- Trench where the poly vinyl chloride (PVC) main line will be laid. This is not necessary for the high density polyethylene (HDPE) which are surface pipes. PVC pipes are sub-surface pipes because they have no UV-treatment, and will thus degrade easily under the sun. HDPE pipes have UV treatment and will be surface pipes
- Connect the PVC or (HDPE) main line to the water pump or high tank. This pipe evacuates water from the source to the farm and is the largest in diameter. The larger the pipe diameter, the more the water it delivers. .
- Join the HDPE or PVC sub-main line to the main line. The sub-main line is smaller in diameter, and so carries less water. It is joined to the main line through PVC or HDPE accessories such as; tees, elbows, saddle clamps, adaptors or valve sockets
- Connect the rain pipe to the sub-main line or the main line where a sub-main line does not exist. This is done with a rain hose connector or a saddle clamp
- Spread the rain hose along the length, and close the terminal end with an end cap
- Connect one rain pipe to another with a connector
A drilling tool is the only tool used when installing a rain hose kit. This is to create an opening on the main or sub-main line to insert the rain pipe ball valve
Rain Hose Pipe Price
Grekkon Limited’s rain hose pipe price is by diameter size. Our rain hose for sale in Kenya is attached to a HDPE, PVC, or delivery/ lay-flat irrigation main or sub-main line when in the farm. These rain hose pipes are made from HDPE material with UV treatment for use in tropical climates.

8 | Irrigates aerially using sprays | Irrigates to the ground via small drops |
9 | Easy to move from section to section in the farm | They are permanently set in one section |
The rain hose pipe price is not a good cost comparison to either drip or sprinkler irrigation. Rather, consider the set up and operational cost per acre under each method of irrigation
Rain hose works well with crops that thrive under sprinkler irrigation. Examples are; onion, garlic, cabbage, traditional vegetables, leafy vegetables and others. Crops that are susceptible to fungal infections if the leaves remain wet for long are irrigated with drip. Examples are; green beans, potato, strawberry, tomato, capsicums, peppers and others
