    D.E. coming out from pool returns

    Hello friends,

    I just replaced the seal and the big oring on the pentairl 4000 series valve. I am experiencing some d.e discharge from the pool returns when I first start the pump. The d.e. discharge stops after a few seconds of operations. Please help me with the problem. Manifold no cracks and filter no rips. I can double check and take it to have inspected by a trained individual?

    Please advice,
    George

    Re: D.E. coming out from pool returns

    Hello friends,

    I am still having a little water coming out of the backwash valve and d.e. from the returns. Could it be that I need a new backwash valve? or perhaps I installed the seal on the valve wrong? I would hate to purchase a new valve if I do not need to.

    Please advice,

    Try moving the valve back and forth a few times, with the pump off, of course. You could have some debris down in there preventing it from fully closing.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Will do that. I must say that when I took out the valve, I cleaned it very well by placing in a bucket and slowly removed all of the old lube. When I placed it back in to position, plenty of lube and care when it to the installation. if the problem with the d.e. continues, I will take it out the valve again and check for proper seal installation.

    Thanks for the advice and will keep you posted!
