    Hi everyone, I have been using WFP for around 5 years. Recently I'm having a problem that's causing me stress to the point where I'm only getting a few jobs done a day.

    My system set up:

    350 litre upright tank
    Shurflo pump
    varistream digital controller
    110 ah leisure battery
    X2 resin bottles

    The problem is this,

    I can be cleaning a few houses with no problems then the water pressure will start to spit as if there is air in the system, over time this stops and the pressure returns, but recently my water has stopped completely and returning to the van I can't get water to come back through? Water level is fine, battery is fine, I disconnect hose from pump to hide reel and run pump at full but nothing after 5 minutes. Check my resin bottle and it's bone dry? One is fine (closest tank but the other is empty? Have to go home, refill bottle and prime system again with a hose pipe from the house tap. This lasts around 3 hours the next day and it does the same?

    I have changed all the o-ring seals in the system but no joy.

    Please help as I'm close to pulling my hair out!

    Thanks in advance J

    If you have, it may not be letting the flow of water throw as the end stop could be facing the wrong way for flow.

    Thanks for the reply, no the only end stop I have is onto the reel but it's never caused any problems over the last few years.

    Does you pump suck or push water through your vessels?

    Water is full in both bottles at the start of the day but over time the water drys out of 2nd DI bottle, the pump sucks it through. I've got the tank, then x2 DI bottles then pump then reel.

    Thanks

    Where is your strainer and have you checked it for blockages?

    There lies your problem IMO, I've been using twin DI for nearly Eleven years. I've tried both ways & had the "dry vessel" issue before. You are MUCH more prone to air ingress if your pump is after the DI vessels. Re-route your pipes to put the vessels after the pump, prime everything again & I can pretty much guarantee your system will be cured regarding air ingress. Check all "O" rings, connections & any fixings also just to be sure.

    This too, as IT can also cause many problems if blocked.
