    DE Filter questions: "blowthrough" and normal pressure?

    I've replaced the gauge, so I'm relatively confident that it is accurate. When I was standing next to the filter when I turned it on the other day, there was a significant swelling of the top of the filter housing as it became pressurized (it seemed like at least 1/2" of vertical height)...

    DE Filter questions: "blowthrough" and normal pressure?

    Actually, I may have just figured something out... The filter valve is designed with 2" inputs, as is the heat pump (and probably the chlorinator). I don't remember if the pump input is stepped down to 1-1/2" or if that's as big as it can be. Everything between the ball valves for the main...

    One problem down, at least one to go... So I received the new filter grids yesterday and installed them. The good news is that with the pool cleaner sucking the silt off of the bottom of the pool, there was no visible "blowthrough". The bad news is that it seemed to work fine for a little...

    DE Filter questions: "blowthrough" and normal pressure?

    Thanks for the advice... I ripped the filter apart, and one of the elements is broken where it fits into the manifold. Doesn't seem like a big enough crack to cause the problems I'm seeing, but I can't find anything else wrong so I'm hoping that's the problem. Harry, the winter around here...

    DE Filter questions: "blowthrough" and normal pressure?

    Hi, Unfortunately I can't get the search feature to work - not sure if I'm inept or if it's broke... I've got an inground pool with a Hayward DE filter that I had a couple of questions about. Filter is 36 square feet, three 1-1/2" return lines (one about 20 feet, one about 30, one about 45...
