YES, Q&E is manufactured to BS EN 15875.
The system must keep within British design standards. i.e high limit cut off switch required
Will have no effect on the pipe but they would be contravening Water & Building Regulations by not putting it in conduit or ducting if used for hot and cold water supply.
No, this has to be copper.
You can use a compression nut&insert (1058934) or Chrome rad connector (1023045).
No, regulations state soft copper must be used for this purpose.
Yes, this will have no effect on the pipes and fittings.
Yes, plaster will not have any effect on the piping. Although we recommend they are buried deep enough not to crack the plaster surface, ideally chased into the brick work.
Normal pipe depth below ground is a minimum 600mm therefore the Q&E Pipe would not withstand the weight of any soil on top of it. However it can be buried in an insulated duct, sealed at both ends.
Q&E will fit directly into most TRVs with the use of a compression nut & insert (1058934).
This is not really recommended due to frost, sunlight, etc.
No, lubricant will invalidate the guarantee and may contravene WRAS approvals
No, The pipe is NOT designed for gas
With an Ethylene Glycol based antifreeze it can carry as low as -20°c
Yes, this will have no effect on the pipe.
Yes, Q&E should be insulated in exactly the same way and to the same thickness as copper.
Not to anything like the same degree.
Please refer to Boiler recommended installation instructions.
No we do not recommend compressed air, only a water pressure test. Water will identify any small leak, and is far safer. Use of leak detecting fluids with an air test may damage the fitting and would invalidate the guarantee
First carry out a low pressure water test at 0.5 – 1 bar when the system is just demountable fittings, then a pressure test at 1.5 x the normal working pressure with a recommended minimum of 10 bar for a minimum of 45 mins.
No, due to the uncontrolled temperature the cooker has potential to reach excessive temperatures. Copper must be used.
Fire regulations state this must be positioned a minimum of 150mm from the downlighting.
No it is not recommended for this.
12 bar at 20 deg
1. 1 litre/minute.
Yes you can, you will need to gently squeeze the pipe with a pair of mole grips before freezing. This will ensure that when the ice plug has been formed it doesn’t shoot out the open end when the pipe is cut.
No, due to the chemicals when in its liquid form, these could harm the pipe. Once the expanding foam has cured Q&E pipe can be safely fed through it. Alternatively the Q&E could be sleeved to give the required protection.
This is exactly as it would be for copper please refer them to the current water regulations.
The thermal linear expansion of PB (Q&E pipe) is 0.00013. 1 metre of pipe will expand by 0.13mm for every 1°C rise in temperature. Therefore 1m of pipe will expand to 1.3mm with a 10°C rise.
Yes, but it should be protected with either a sleeve or temporally taped over to avoid the pipe being scratched, and then the tape must be removed after insertion through the wall.
We do not produce a purpose made fitting, however this can be achieved with the use of a compression fitting designed for use on ½” lead pipes, along with a MALE IRON in the Q&E pipe end.
We can only state that our Q&E is WRAS approved for drinking water.
Yes, as are all plastics to an extent. Where Q&E is used externally it should be waterproofed lagged to give thermal and ultra violet radiation protection.
The use of recommended inhibitors from the FERNOX and SENTINEL ranges will have no effect on pipe performance.
Yes, it is perfectly safe for this use.
Please use our compression nut & inserts or Q&E male irons.
Refer to the Q&E Technical guide.
16mm pipe = 120ml, 20mm pipe = 240ml, 25mm pipe= 360ml
No. Denso tape should not be allowed to come into contact with Q&E.
Yes although the OLD Q&E pipe will require a liner to a compression fitting PLUS a nut and insert at the other end to connect 16MM Q&E.
The blanking elbow is recommended for radiator circuits (1042320) or Uponor Test plugs maybe used for standard tests.
Yes, the smooth bore of Q&E prohibits scale build up.
Yes, unlike copper, no matter how soft (acidic) the water is, it will not corrode Q&E pipe.
Sustained exposure to chlorine above 0.5ppm (parts per million) should be avoided. These conditions do not normally arise in UK potable water supplies. Q&E is not suitable for use in high chlorine concentration systems – i.e. swimming pools or decorative water features.
The rings are to be used for all Q&E connections, and are coloured for: Blue=cold , Red=Hot.
This will prevent cross connections to pipeworks dueing installation.
Standard pipe was introduced in 1980 in the UK under WIRSBO, and has in 2012 completed 40 years in production throughout Europe and the world.
Yes, this is 7 x the pipe diameter.
Whilst this should be avoided there is no need to discard the pipe as it may only reduce the pipe strength by approx 10%. However if the wall of the pipe is damaged in any way this must then be repaired or replaced.
Yes, this will have no detrimental effect on the pipe.
NO this is not recommended.
Yes, they will need to use PTFE tape with the fitting or loctite 55. Do NOT use Boss White on the fitting.
You can use individual rolls of Uponor conduit. Refer to Uponor price guide.
Yes in exactly the same way as copper.
Advise a minimum distance of 12″ with a cold wet rag wrapped around the copper pipe to limit the amount of heat transfer through the pipe.
No, because the maximum water temperature of solid fuel boilers is uncontrolled and can reach excessive temperatures.
Any gate valves or Ball valves are suitable for this use c/w Q&E Adaptors.
No tape should be installed onto our Q&E pipe and fittings.
We do a product known as MLCP which has an aluminium layer within the wall thickness of the pipe.
YES, we would suggest that you contact us for this application.
Q&E should not be used for primary circuit of a solar heating system as the temperature cannot be thermostatically controlled.
Refer to the oil boiler manufacturer.
