this is evident by the green ring located between the screw cap and the body being visible. ensure that all pipe and fittings are free from scores and scratch marks and kept free from dirt and debris prior to installation. connecting to copper pipe • twistloc fittings are designed for use on metric copper pipe which conforms to bs en 1057-r520. • when installing with copper pipe cut the pipe with an appropriate pipe cutter designed for use with copper pipe. • pipe ends should be inspected carefully and remove all burrs or swarf. • push the pipe firmly into the fitting until the pipe passes both the collets (gripper) and the ‘o’ ring and is engaged properly. • twist the screw cap until the green coloured ring is no longer visible. this locks the collet in place and at the same time increases the pressure on the o ring seal around the pipe for greater security. connecting to a compression fitting compression fittings which comply with bs en 1254 are suitable for use with twistloc pipe. • using the twistloc pipe cutters cut the pipe squarely and insert the twistloc pipe insert. • if required apply ptfe tape to the pipe. • fully insert the pipe into the fitting. • tighten the compression nut. do not over tighten as this can compress the pipe too much. • oil based jointing compounds are not suitable for use with twistloc pipe • a twistloc pipe insert must always be used with twistloc pipe. • copper olives should be used rather than brass. • after tightening, twistloc pipe will not rotate in a compression fitting. connecting near a soldered joint soldering work should always be carried out before twistloc fittings are installed. if this is not possible you must observe the following precautions. • don’t allow flux to come into contact with twistloc pipe or fittings. do not use excessive amounts of flux, as flux runs can occur pipe end only. • solder must not come into contact with twistloc pipes and fittings. • twistloc pipe and fittings can become excessively hot with soldering taking place nearby. to minimise the effects of this the copper pipe should be wrapped in a damp cloth. this should minimise any likely heat transfer. • systems should be flushed with water to remove any internal flux residues. • if any plastic pipework or fittings have been damaged during the soldering process they should be replaced immediately. connecting to other brands of pipe twistloc insist on rigorous testing to ensure that all of our pipes and fittings are manufactured within certain tolerances. as we are unable to guarantee those tolerances used by other manufacturers, we are unable to recommend our fittings be used with any other plastic pipe or fittings be used with ours. connecting to chrome plated or stainless steel pipe due to the relative surface hardness of these materials twistloc fittings cannot be connected directly to chrome plated or stainless steel pipe. connection to boilers twistloc fittings and valves should never be connected directly to a boiler. although most modern boilers have a high limit thermostat, residual heat can be conducted by the heat exchanger. therefore twistloc recommend a minimum of 1 metre from the boiler casing should be run in copper pipe unless otherwise stated in the boiler manufacturer’s installation literature. a gravity primary circuit operating on an uncontrolled cooking range or solid fuel boiler should then be run entirely in copper and the heating circuit run in copper for the first metre. inside the pipe during soldering. only apply flux to the copper all appliances should have safety devices to make sure they cannot operate above the working temperature and pressure range. if safety devices are not incorporated within the appliance then external controls will be needed. water meters (and other devices) can contain check valves that prevent the expansion of heated water back down the main supply from a combi-boiler. if plastic pipe is to be used, a suitable expansion vessel must be fitted. this is especially important to consider if a water meter is fitted retrospectively. twistloc do not recommend the use of plastic pipe on the main supply between a water meter and a combi boiler if an expansion vessel is not fitted. twistloc products should not be fitted to a sealed system, oil boiler, a back fired boiler or other uncontrolled heat source. connecting to a mains water supply a stop tap should be used when connecting to a mains water supply. connecting to appliances twistloc manufacture a number of installations for connecting to appliances such as washing machines, dishwashers and even small bore water filters. pipe clipping distances should always be adhered to when installing valves. where to use twistloc twistloc has been designed for use in most domestic and commercial hot & cold water and heating applications. installation work should be carried out using good plumbing practice as outlined in the installation guide. where not to use twistloc twistloc should not be used in the following applications: twistloc should not be installed in a continuously operated re-circulating systems (secondary hot water circulation/ring main installations) for carrying gas, compressed air or fuel oil or for use in direct sunlight and ultra violet light. we recommend that if pipework and fittings are used externally that they are either covered or painted to avoid direct uv exposure. areas contaminated with petroleum and oil derivatives the conveyance of water with a high concentration of chlorine. this can sometimes be found in swimming pools, hot tubs or decorative water features. in a solar heating system as a primary circuit. temperatures cannot be thermostatically controlled. cabling through joists the introduction of plastic pipe and fittings allows pipe to be easily curved and cabled through drilled joists or i-beams. this offers the plumber the following benefits: • floorboards can be laid allowing the plumber to work from below before the ceiling is installed. • fewer chances of piercing the pipe when nailing floorboards into place. drilling through the joists • drilled holes in joists should be large enough to allow for thermal movement of pipe. • hole diameters should be no greater than 0.25 of the depth of the • the minimum distance between a hole and a notch in the same • they should be not less than 3 diameters (centre to centre) apart and should be located between 0.25 and 0.4 times the span from • for engineered joists, piping can be properly installed through holes in the web section without damaging flange members even when the preformed holes do not align on the plan. please note that the building regulations approved document a gives exact instructions on the drilling of floor joists. please refer to sitework pipe support for surface bounted pipe joist and should be drilled on the neutral axis. joist should not be less than 100mm. this document for full

flexibility of the pipe to produce a bend which can be clipped into shape, or tighter still with a 15mm cold forming bend, subject to the following limits. pipe size min radius with clips min radius with cold forming bend 90mm concealed pipework when installing the twistloc system in concrete and masonry the pipe should be run in conduit pipe with access boxes for the fittings so that all pipe can be removable for replacement and maintenance therefore complying with the requirements of the water regulations. pipes through walls and floors to protect twistloc pipe and fittings, always sleeve in conduit when passing through walls and floors. do not use expanding foam in its initial wet state as the chemicals in the foam can cause a chemical reaction. to reduce noise and to act as a fire stop the annular gap between the pipe and the conduit should be filled with a resilient material. it is also suggested that pipework should be run in a conduit when laying it next to metalwork. this will protect the pipe from any sharp edges due to thermal movement. burying pipework in screed, concrete floors or walls the water bye-laws state that distribution pipework must be ac- cessible to facilitate its removal after replacement. pipework must therefore be placed in conduit before being buried. to prevent against frost we also recommend insulating the pipework. twistloc for use in timber and steel framed buildings twistloc is ideal for use in these applications. it is important during the installation process to ensure that the structural integrity of the vapour layer or the property itself is not compromised. pipework should be installed in the inside of any thermal insulation. if the architect did not allow for a recess to allow this to happen, conduit must be used. metal tape where pipework is in or behind wall surfaces and would otherwise not be detected by a metal detector or similar equipment, a metallic tape should be applied to the pipework. do not attach tape directly to twistloc pipe and fittings. connecting to a storage vessel we offer a range of tank connectors for connection to cold water storage tanks in 15mm, 22mm and 28mm. when installing do not use any jointing compound on the connector. hand tightening is all that is needed. further mechanical tightening will damage the fitting. connecting to boilers and heaters a minimum length of 1mtr of copper pipe must be installed before connecting to a twistloc pipework system. all connections should be made in accordance with the requirements of bs5955 part 8. to avoid serious overheating trapped air must be purged from the heating system before the boiler is operated. always refer to the boiler manufacturers’ installation instructions. twistloc within internal drywall systems one of the benefits of twistloc is that it can easily be cabled within wall structures during the construction process. this is best seen when using 10mm pipe and elbows as a feed to radiators. by incorpo- rating this method the appearance of pipework on show in the home can be significantly reduced. continuously operated re-circulating systems (secondary hot water circulation / ring main installations) plastic plumbing systems are not suitable for use on any continuously operated re-circulating systems (secondary hot water circulation / ring main systems). these installations differ greatly from traditional domestic installations and therefore twistloc pipe and fittings may not be used. freezing for maintenance/system modification twistloc pipe can be frozen for maintenance/repairs without damage to the system. when freezing equipment manufacturers’ instructions should be followed. always freeze at a reasonable distance from where pipe is to be cut. painting twistloc pipe and fittings twistloc can be painted with either a water based paint or an oil based paint with an undercoat. cellulose based paints, paint strippers, thinners, flux, acid based descalents or aggressive cleaning products must not be used. corrosion inhibitors we have tested twistloc pipe and fittings with fernox & sentinel and have approved them for use with our fittings. antifreeze we only approve antifreezes which are based on ethylene glycol mixtures. electrical safety please contact a registered electrical contractor or your local electrical authority with regards to bonding, continuity and electrical safety. precautions insulating pipe when installing pipe in an unheated area or outside insulation is required in accordance with bs6700 and bs5422to protect from frost damage. these requirements are the same as for copper pipe. uv protection twistloc is suitable for use outdoors however it should either be painted or covered with insulation to protect against exposure to uv rays. pressure testing it is essential that a full system check takes place upon completion of an installation. before carrying out any test you must ensure that all twistloc pipe and fittings are installed correctly. we suggest a test of 2bar for 10 minutes followed by 10bar for 10 minutes. any products that are not manufactured by twistloc and are unable to withstand the test pressures should be disconnected during the test and capped off using the twistloc end stop cap. pressure testing is not a substitute for making sure pipe and fittings are correctly installed. for details on how to make a good joint please refer to the beginning of the installation guide. advisory service for all technical enquiries please complete the contact form or call 01623 836814 maximum torque figures the
