Yes, but we suggest that you double the amount of FX2 to 5 litres. If the distributor / spreader tube, which directs the incoming water towards the far side of the radiator, has broken away, so that the entrance and exit are effectively only 1/2" apart, any flushing effect on that radiator will be minimal. Conversion to opposing inlet and outlet valves is a better long term proposition.

Yes, but connection of the CF30 should be on to the circulator pump fittings, and not on to a radiator, otherwise the small bore tubing will drastically reduce the flow rate, and the system power flush will be less successful than normal. We advise using 5 litres of FX2 (instead of the usual 2.5 litres), to ensure the particles of debris are dispersed in as fine a form as possible. See similar questions...

These older valves are identified by having both pipe connections in one radiator valve at one side of the radiator. If new radiators are being fitted it may be advisable to also renew the valves. See similar questions...

It's best to set your TRV to a middle setting and see if the room is warm enough. If the room is too warm, turn the TRV down by 1, if the room is too cold, turn the TRV up by 1. A middle setting corresponds to approximately 20ºC (68F). Do NOT turn the TRV fully ON or fully OFF to make the room you are in warmer or cooler - this will waste fuel. Turn it a little way and let it do the work. See similar questions...

Minerals & deposits build up over time which can cause overheating. Bar's Leaks Radiator Flush will help your cooling system by removing these deposits and leaving your system factory clean. See similar questions...

All our ready made and made to measure covers come with complete fixing instructions. Assembly of the cover only takes a few minutes. Both ready made and made to measure designs use "wall hook" fixings and once these are fitted to the wall removal, and repositioning, of the whole cover for access takes just seconds. In this way the whole cover surround can be taken off very easily for full access. See similar questions...

If radiators on a single pipe system have severe deposit build-ups, or cold panels, then the Power flush is not likely to be successful. BS7593:2006 advises against power flushing a single pipe system. If you do take on such a system, improve the chances of success by pre-treating with two litres of HYPER-FLUSH, and operate the flow reverser more often than usual whilst flushing individual radiators.

We recommend when replacing power valves they need to be replaced with the same type and model and they are matched, the amplifier will also need to be re biased to match the new valves to the amplifier. All work of this nature must be carried out by a qualified engineer. See similar questions...

No, Bar's Leaks Radiator Flush is a non-acid formula and is safe to use on all cooling system materials. Harmless to all parts of the cooing system, including aluminum. See similar questions...

When using a power soak with a valve amplifier or combo because you tend to drive the amplifier harder and louder the life expectancy of the power valves could be shortened. See similar questions...

New houses may have this, because of new housing regulations. However, existing older systems will not usually have an AUTOMATIC BYPASS (PRESSURE BALANCING) VALVE, or ABV fitted to the system.These are required to cater for the possibility that the majority of radiators are closed off due to low TRV settings, but high room thermostat settings keeping the boiler cycling. Since the circulating pump would still be running, the pressure in the system would increase. See similar questions...

Yes. Sometimes it is just not possible to collect all of your data via the Internet. In those circumstances, DatStat Illume can serve as a data entry mechanism. Advantages include real-time validations to ensure data are of the correct type and format, and immediate access to the data via the Web Console. In addition, Illume can be configured for double data entry, such that inconsistencies between entries are flagged for correction. See similar questions...

It will vary from house to house, but generally about five hours for a three bed house with a vented system, but less time for a sealed / combi system, because you don’t have to cap off the cold feed and expansion piping. See similar questions...

Yes you can. FX2 liquid, and HYPER-FLUSH, can be used on plastic pipework systems, and will not damage either the pipework, or the ‘O’ ring materials. If the system is a gravity hot water system, there is probably an anti-gravity / non return valve in the radiator circuit. If the non return valve is accessible, either loop it out, or remove the plunger so that it doesn't prevent the flow of water in one direction. See similar questions...

Yes. However, the amount of air in the radiators is usually small. If you keep the water level in the CF30 tank at least 10 cm above the minimum, you'll minimise the air to be bled from radiators. See similar questions...

We recommend all power valves are replaced at the same time you use matched valves and the amplifier will need to be biased to match your new valves. All work of this nature must be carried out by a qualified engineer. See similar questions...

A hot flush is a sudden feeling of being overheated, usually accompanied by sweating and redness in the face. It is the most common symptom women experience during the years surrounding menopause (and sometimes for many years afterwards). For more information, see Hormones and hot flushes.

Yes. Double-entry visa means you can enter Mainland China twice. Hong Kong is a Special Administrative Region and has its own visa policy. When you leave Mainland China for Hong Kong, your visa is used and you need to have another visa if you wish to come back to Mainland China for a second time. Remember, each time you enter China from Hong Kong or Macau, you need one entry. See similar questions...
