If mechanical filtration was equal to DE then I can see no reason for DE's continued existence. You're right it is subjective. Kind of like acquiring a taste for fine wine. I have used both on various pools and can tell the difference, although I wish I couldn't. I suppose those that have never...

I ask because we all know that or should know that cartridge filters go to 10 microns. With that flakes or minute particles are still visible especially under light. DE filters go down to 5 micron and the water appears polished. If you were to take the 95% of the load off the DE filter with a...

Has anyone tried running DE filter behind a cartridge filter? Head pressure permitting.

Thanks for the input

I had to replace my IC 40 and this one has a plastic grate or screen that fits inside the intake or exhaust of the unit. The old one did not have this. I assume it is to protect the flow sensor but for the life of me I can't find anything on this part or which end to install it. Anybody have an...

CUTiger I checked out Hayward Super Pump. They offer what appears to be composite impellers but the attached picture shows holes directly over each vane. They very well could be mecahical fastening points for a two piece impeller or it may be one piece and those are something to due with the...

CUTiger Thanks I will check it out

Overall I have been very happy with the intelliflo. Again I am not bashing and understand they need to be cost conscience. In all fairness the impeller material is likely marlon or some sort of rugged composite and not just a cheap plastic. I use the term plastic as a generic reference. My guess...

Hehe No the weir is the negative edge not the drop to the catch basin. (The crest of an overflow spillway on a large dam is often called a weir. Weirs, referred to as low head barrier dams). As earlier indicated I have 4 inlets. No less than two service the intelliflo pump at any time. Sorry...

The variable speed also runs a suction side cleaner and can be used if need be to assist in a negative edge application. The variable speed is also a great option to run a chlorine generator. The pump is not cavitating (no errosion seen) nor is there excessive vaccuum as I can remove the...

Sure (4) 2" intakes and (6) returns, 20'+- run. No 90 deg fittings all done with sweeps made from 45's. Quad 80 DE filter. Filter pressure @ 1500+- rpm is 10psi clean and 15-16 dirty and increases 5 to 8 psi @3450. Equipment is 2+- feet below water level. In short there is nothing remarkable...

JamesW thanks for the response. The schematic of the EcoStar seems very close to that of the intelliflo. It does not indicate the impeller material and I see virtually identical engineering. But then I may be missing something. Can you give me your opinion as to why this is a superior pump...

I currently have a 16k salt pool with a intelliflo VS 3050 that is 2.5 years in service. Apparently it has had a very slow seal leak and as salt will do, created excessive internal corrosion. When the leak became evident I opened the pump to find a separated impeller a broken retaining bolt and...

Take a look at the Pentair Quad I have used them on two pools and like the cartridge ease. They are much easier to clean over the fin style de filters.

Thank you Waterworks, I decided on a Intelliflo and then added an additional 2 hp pump for a water feature. Both will operate from the catch basin and the Intelliflo will be valved to switch to the pool drains for cleaning cycles. I also doubt the water feature would be used without the...

Thank you very much it does help. I have to now go to my neighbor who has a 30' + - negative edge and is acheving the effect with one 3hp pump. Perhaps the head is much less. Thanks again

Hello all, I am embarking on a pool build in our home in Mexico. That said, I am trying to educate myself on infinity edge pools. Does anyone have a basic plumbing schematic with pipe diameters and volume requirements? This pool will be about 15,000 gals with approximately 30 feet of negative...

My neighbor is putting in a 18,000gal IG pool. The PB is installing a Sta Rite 300sqft cartridge filter and a Hayward Navigator suction side cleaner. After doing a search on the forum it seemed most are using cartridge filters of 400 or more sf for that size pool. My thought to begin with was...

When my Quad 80 came it did say fns plus on the box but it was the correct filter. I questioned that as well.

I believe a heat pump is supposed to cycle and warm the coils periodically to remove or prevent ice from forming. I know when they ice up the heat pump will not perform. I had this happen on a heat pump for a HVAC setup in our home. As I recall there was a reversing valve that was not performing...

You are right it is confusing. I just installed an Easy Touch which I would assume is very similar to yours. I put the intelliflo on the first relay and attached the dc relay leads to the button marked pump. I believe in the software that is the default location. Is your booster pump 110 vac...

I doubt it takes very much to cause the blow back. At first glance my grids looked good but there were tears right along the bottom edge that you did not see until you moved the fabric one way or the other. Regardless, any void is an avenue for the DE to go back to the pool. But I believe you...

The circuit terminology was one thing. They speak long and loud about naming circuits and I was thinking they meant an electrical circuit. But in actuality they mean programs. For instance by my way of thinking my unit has 4 relays which are for four separate circuits controlled by 4 breakers. I...

If anyone is interested my Easy Touch control avoided the trash can. Yesterday I was finally able to program the unit. Pentair's software and or terminology is truly a nightmare. For instance they use the term circuit to describe a programmed function. So to take a page from the manual they say...

A small amount of DE blow back on recharge seems to be normal. At least it has done that on both my DE filters. You need to tear down the filter and remove the grids to look for tears. I found mine to be on all the hard edges of the grids along the bottom edge. I had a top mount manifold. They...

EskimoPie, Thanks for your time you have been very kind to take so much time with me. I see we are neighbors, hope you are enjoying this beautiful weather.

Well I wiped the memory then reprogramed it again and now it runs continuously. Will not shut off. I did however find an easy way to turn it off and on. You just have to throw the breaker. That's what I call automation. The trash man cometh. This unit is crafted well meaning the fit and finish...
