pressure gauge should be here tomorrow,   first time testing pressure,     Fieldsy,   can you go through it with me.     will i need to connect hosepipe to it,    or hozelock connections,
do i just turn it on full and leave for a few minutes and take the reading of pressure on dial

[Fieldsy]

Hi,

My gauge had a tap connection already fitted ( the type you just screw on to an outside tap). Just had to twist it on and turn on tap. Pressure shows immediately on gauge.

One bit of advice I got from Phil at vyair, consider fitting a bypass to the waste tap. Reason being when you find the sweet spot for optimum ro performance between tds and waste, you leave the tap as it is and need never adjust it again. The bypass hose runs off a t piece before the waste tap and rejoins the waste hose via another t piece after it. A second tap or gate valve / ball valve etc. is fitted to the bypass hose, you simply open it to flush and close it to produce pure.

and an inline tds meter ( If you don't already have one )
It simplifies things so much and will preserve resin. You can open the waste bypass valve , instantly check the tds and when its as low as it will go, close it and start producing pure.

did you get the system 'custom' built so to speak? as his website doesnt show complete systems?

[Fieldsy]

What a great idea Mr Bitt, I've got a spare tap, cos as you know Phil usually provides loads of extra bits . Great company to deal with. Will be giving that a go

@Jakey,

It couldn't have been simpler m8. The membrane was pre fitted. The prefilters were in the containers, just needed to take the wrappers off and screw back up again. It was just a case of getting all the pipework connected in the right order .

Hardest bit was securing the membrane housing to the ply, cos its reasonably heavy and could use two men to keep it straight whilst fitting the brackets.............but a knee and a spirit level in the right place did it ok on my own .

Phil supplies everything you need and more.

i still cant get my head around your description mr bit,     im lost all togeather.

pressure gauge should be here tomorrow.   from vyair.

I usually flush mine every time i make water.

I have got a t piece in to stop the RO spike tho

tds after RO
tds after 1st Di
tds after 2nd Di

holly molley,     im too used to my simple 300 ro set-up.

mind that took some learning but simples when you get used to it

Looks complicated but it ain't at all

Its very straightforward , the attached pic should help. Ignore the fact its all compression joined and brass plumbed. Its just what I had lying around and my system at the time was fitted in my first floor flat so had to be completely fail safe and free from leaks.

The red needle valve to the right is my waste valve set to its optimum ratio for waste/pure.
Notice the bypass to the left and the ball lever, its open to flush the system. If I closed it a quarter of a turn it would start making pure.

Most 4040 ro's will just have a plastic ball lever style tap on the waste hose, in order to flush it you will have to fully open it and then partially close it again to make pure water. Problem is setting the tap back in the right place each time, some people mark the spot the tap needs to be set to.
A needle valve is more finely adjustable ( the tap with the red wheel in the pic ) and retains continuity because if you fit a bypass and second tap as I suggest you need never adjust it again.

If buying from vyair, just speak to Phil about it. I am sure he can supply you all fittings and explain it to you.

Good idea with one caveat.  You still need to check it occasionally.  Input water pressure and temperature can make a difference to your sweet spot, so you do need the odd check, certainly between summer and winter.

Good point but that goes for anything I guess.
My 4040 has been pretty consistent though tbh, having an inline pressure gauge,  tds meter and needle valve for the waste does make any checks and fine adjustments a lot quicker and simpler though.

@Mr Bitt, blimey thats better than some plumbing I've seen.....lol

Gonna give this a go at the weekend mate, as I've got a spare tap. Will run the by pass, as Phil provided some y joints and bits and pieces aswell.


Nice idea mate
