You can remove the water softner completely. The softener removes the calcium and magnesium ions from the water and replaces them with sodium ions. Sodium ions are much kinder to r/o membranes.

The first thing I would do is remove the salt wash and replace both the prefilters, 1 with a sediment filter and the other a carbon block filter. Couple the inlet hose to the first prefilter (sediment) and direct the waste to a drain.

Open the waste tap totally and switch on the tap. Allow that to flush for a while, say 10 minutes. Then switch the water off. You then want to uncouple the pipe that goes from the r/o to the tank and put another length of hose on it. You need to do this so you can take pure water samples to test the tds of.

Switch tap water back on and slowly close the waste tap, but not completely. You need to get to a spot where the waste is about the same quantity as the pure. Take regular samples of the pure, slightly opening and closing the tap until you achieve the best result. As I said earlier, if the membrane is ok then you will be getting a tds of around 5-6.

If it isn't, then you will need to replace the membrane. Depending on water pressure, it will either be an HF4 or HF5.

If the membrane has been allowed to dry out or has stood idle for any length of time, then you may have to replace it - sorry.

Once you get the system sorted, then you can fill it with the correct salt and put it back in the system. You may need to phone Streamline and ask them when the salt needs to be changed and how you know when to change it.

I can't get you their telephone number. I have a lovely 82 page 2013 catalogue on my desk - not a telephone number or address to be seen anywhere - what a waste of money.

thank you so much spruce

I hope I have been of some help.

Water purification seems very complicated when you first start, but once you get your head around it, it becomes quite simple.

You also need to prepare your van so it's ready for winter. You need to make sure the membranes don't freeze, so you need a satisfactory form of heater with frost stat to ensure that doesn't happen. While winter is still a far while off, its good to get an action plan underway within the next few months so you don't get caught out.

I wish you the best. Please keep us informed of how you are progressing.

Your controller will compenate for height. As far as the setting is concerned, try at about 40 and see how you get on. As you get quicker cleaning the windows you will probably need to run the speed a bit higher for a higher water flow.

First cleans WFP will take time, so plan on a poor month financially. You will also be physically exhausted. Second cleans will be much easier provided you have 'taken the pain' on the first cleans. By the time the third and fourth clean are done, you will be much quicker as the windows will be 'sterile' and you will be more confident at using the pole.

right I replaced sediment and carbon and took away the water softener which was after carbon filter and I could only get it down to 015 which I thought was strange so I added the softener again and water came down to 007 so my question is there a 10 inch water softener for theses systems instead of the big blue bottle

A 10" softener won't last '5 minutes' I'm afraid.

would this be any good for my system

http://www.ebay.co.uk/itm/D-D-125-PSI-RO-Booster-Pump-For-Reverse-Osmosis-Unit-/330642377244?pt=UK_Pet_Supplies_Fish&hash=item4cfbd24a1c#ht_1000wt_1091

The pump in your link looks like it only has a 1.2 ltr per minute flow rate.
I've recently got a 4040 ro and I use a Clarke CBM240E booster pump.

Any I'm in West Sussex Horsham also a hard water area,I have a pure freedom system  20 inch carbon and  20 sediment filters then into a 40 inch ro I change my filters every three months regardless of my tds reading and change my resin when readings start to rise over the last five and a half years all of my ro membranes only last approx 18 to 20 months my tds reading out of tap is 120 I also flush my system every couple of weeks for approx 45 mins.i feel it's just the hard wate that reduces the life span of filters and membranes in our area. Hope that's Been of help
