Totally depends on what it’s used for. Industrially, usually above 4 ppm. Lots of plants have hardness analysers which alarm at that level.
Domestically, if I’m honest , I don’t know. I’d take a guess at around the 40-50ppm mark.
I very much doubt that nothing was added. I’ve worked on many RO...
Still applies mate.
And although great strides have been made with the removal of lead piping, there’s still thousands possibly millions of people still supplied through lead pipes. I know I am. For this reason alone, phosphoric acid is dosed into the water supply. It coats the lead so I...
Looks a decent solution that mate.
I once worked ( as a contractor ) in a well known soft drink company’s plant and they had blending valves to increase the hardness again after softening. A small amount of hard water was blended into the softened water to achieve the required level. If these...
Although you say your water is soft, it isn’t ‘technically’ soft, it’s just less hard than other areas which, as I have already stated, water hardness does vary regionally in Britain. It still contains the minerals required. RO and properly softened water doesn’t.
Read the literature supplied...
A glass or two won't harm you but long term, yes its unsafe.
It can 'strip' the minerals from the blood/bones. The less that is in the water, the more it will crave and absorb. Demineralised water is highly corrosive.
RO water also has a lower pH, it can come off some RO systems as low as 5...
Yes it's true. And yes it is theoretically. '100% pure water' is not safe either. 'Pure water' is only really used industrially, in high pressure boilers etc. The minerals that everyone likes to remove are actually necessary in healthy , safe drinking water.
RO is used to produce drinking...
Good, I'm glad to hear it ! The only real safe and easy way to deal with scale in kettles / coffee machines is regular descaling. Tap water should be hard, it's essential that it contains minerals. Yes, regionally, the water hardness varies greatly across the country, but they all pass hard...
Reverse Osmosis IS filtration. I believe its currently the finest form of filtration known. Any water from a reverse osmosis system will need re-mineralisation afterwards.
Parm is spot on. Generally, all skilled trades are bought in , mainly from The Philippines, India, Pakistan, Bangladesh and Nepal. Most of the welders, in the power / oil and gas industries are Philipine and are already trained to a high standard.
You would need to find out a lot more about...
Yes they have a training school at Tipton. Highly regarded in the Engineering Construction Industry. As Parm says, if you can get in , you'll be sorted with probably the best training going.
Agree with 8ob, threading the inside just won't work. The tap won't be the right size either. You need Plain/female threaded adapter . Cheap enough and you will get a proper job at the end of it. Just try places like Pipe Centre or BSS as not all pipe and fittings places carry plastic.
Parm I don't think that Concur is what you're looking for . We use it and it's really just an auditing service, it is good and easy to use but the expenses still have to be approved by someone internally too. Sorry but I have no idea of any others. You may not be able to use it as I would...
The air from a compressor is contaminated as previously stated. If I remember correctly, it can be passed through a carbon filter to make it suitable for breathing. I'm 99% certain that it's what shot blasters use.
A previous employer bought a blue brand stick / tig inverter from them for light duties around the workshop.....it was pretty decent for the money to be fair. Don't know what their mig sets are like though.Service from the company was good if I remember correctly.
