What is winter sprinklers?
Sprinklers wintering is essential for irrigation systems in regions where cold winter weather is likely. The water expands when it freezes, and any water trapped in the spraying system will bother to plumbing. Without winter homeowners risk cracked pipes and fittings. The rigid polyvinyl chloride (PVC) tubes are more vulnerable to the effects of frost and cold, as well as more flexible polyethylene plumbing can burst unless winter winter is made. Available three types of winter alternation are the air compressor or "blowing" method, manual outflow method and automatic discharge method. If the preferred method of winter of sprinkler is not known, the outbreak method is generally recommended. A air compressor is required for the outbreak of winter sprinkler. Compressors are available from the equipment rental. After switching off the water supply, the compressor is connected to the main line of the spraying system, usually a quick binding or hose bib. Air pressure should be inYested slowly to about £ 50 per square inch (345 kpaScal). If the heads of sprinklers do not occur, the pressure should gradually increase as long as it does, but the pressure should not rise above 80 dogs (550 kpaascal). After the lines are dry, the air compressor should be switched off, but the insulating valves should be left open halfway and the test taps should be left fully open.
Manual discharge is possible the simplest method of winter. Turning the water supply and opening the manual drain valves cleans the main line. It is also necessary to open a stop and waste valve or boiler drain to drain the remaining water. Try the cocks on the back tokuned. After the system is erased, manual valves are closed again and the sprinkler system is ready for winter.
Automatic discharge is triggered by low water pressure and opens the valve when the pressure inside the pipes toForest on 10 dogs (about 70 kpaascal). Switching off the water supply and activating the system pressure release will open automatic valves and empty the main line. As with manual discharge, a drain or waste valve or waste valve or waste valve or boiler drain must be opened to release water trapped between the shut -off valve and the return flow. Opening of the test cocks will delete the backward device.
The use of the blowing method for winterurization of sprinkler is not recommended for amateurs. If the system is too fast or the pressure can rise too high, sprinklers may suffer serious damage. For the best results, this procedure should be carried out by a qualified license professional.
