  • Barbed fittings are designed for use with low pressure pipe, such as drip watering systems. The barbed fittings are low cost and can neatly be installed inside the pipe using hot water. Before fitting barbed connections ensure that the pressures used in the system will be below 4.0 bar (drip systems usually operate at around 1 bar) and are only designed for above-ground installations. Barbed fittings can only be used with soft walled above ground pipe - generally this is soft enough to distort when squeezed hard. To fit the barbed connectors use hot water (being careful not to scald yourself). Dip the pipe end into the hot water for 5 seconds or so to soften it. The push onto the barbs in an up-and-down motion until the pipe has gone over all the barbs. The video below demonstrates the best way of installing the fittings into the pipes.    

  • According to a study by Lancaster University, the addition of green walls in city environments could reduce the amount of particulate matter (PM) by 60% and the amount of Nitrogen Dioxide (NO2) by 40%. Previous studies, the report states, had not taken into account the enhanced residence time of air in street canyons, giving much lower benefits for green walls. The report concluded that the "judicious use of vegetation can create an efficient urban pollutant filter, yielding rapid and sustained improvements in street-level air quality in dense urban areas." Green walls require irrigation to allow them to thrive in harsh city environment - Access Irrigation can design and supply appropriate systems.

  • Barbed fittings are a neat and low cost method of putting fittings into low pressure irrigation systems such as border drip lines. Provided the components are of a good quality and the pipe has been warmed prior to being pushed onto the barbs, the fittings will stand 4 bar pressure without blowing off. Generally speaking there is no need to add jubilee type clips to the outside of the barbed fitting. The disadvantage of using a jubilee clip is that the fitting becomes bulky and ugly and also if the clip is tightened up too much, the barbed fitting can be cracked - causing the very problem the jubilee clip was meant to prevent! For this reason, we do not recommend the use of jubilee type clips on barbed fittings. If you do have a situation where it is vitally important that the fittings do not come off - for example drip lines under a sudum blanked on a green roof - then we recommend our Pozilock range of fittings. The Pozilock fitting consists of an inner fitting with a barb and an outer compression ring. The pipe is pushed over the barb (no warming of the pipe is necessary) then the grip ring is tightened over the top of the barb. As there is only a single inner barb, the fitting is quicker to make up than a traditional barbed fitting but is much more secure. The fitting also looks much neater than a barbed fitting and jubilee clip.

  • Under previous 'hosepipe bans' only the washing of cars and the watering of domestic gardens was restricted. The 2012 restrictions however use new legislation that has been passed since the last drought. This widens the scope of the restrictions and now covers sports pitches that are not used for international matches. These new restrictions will adversely affect club level rugby, football and bowls clubs. One method of circumventing the restrictions is to fill storage tanks from rainwater caught off the clubhouse roofs. This requires and investment in larger tanks and some infrastructure, but will pay back the cost of the equipment by being able to use the free water source. With mains water costing £1.50 per cubic meter in some places, the cost of a large galvanised storage tank can be paid back in just a few seasons.
