I hear ya! I have 2 "more expensive than they should be" ~adult millennials of my own. Sigh.

I AM curious Matt why you haven't done the cartridge conversion yourself yet? I see a number of posts saying you've switch out to C&C when the time comes though...?

Thank you! After I posted the question (I had never considered the possibility before) I did find a number of posts here, but not a definitive one for a "one for one" cartridge replacement suggestions. The CCP520 cartridges are 7" in diameter (instead of 6.25") but I suspect there's enough...

That's weird, I thought I was already a supporter. Sorry about that. I also subscribe to TFP's Pool Math App.

Are you saying that I could retro-fit the Quad100 with Clean & Clear Cartridges? (Any idea what the filter part number might be (or equivalent C&C Model #)?) Or would I have to completely replace the filter housing unit itself? Taking a basic look at the Clean & Clear, they do seem almost...

I will add that even with the pre-filter sock in the weir basket (and I am diligent about using it), the filter does reduce it's flow by end of season enough to have a noticeable slowing of the flow to our waterfall. A bigger part of the reason I am re-thinking the system.

Yes that seems to be why the original installer didn't put in the MPV in the first place (and I guess less is more). I CAN run a whole 6 month season without backwash/cleaning the Quad100 as intended. It's only to make the end-of-season cleaning a bit easier that I was contemplating adding...

I haven't yet been able to find another good installer (mine disappeared shortly after the original build in 2015), so since I am somewhat technically inclined I took on all of the maintenance from the beginning and want to do some updates to our simple system. Currently I have 1.5" plumbing to...

Thank you, I am learning so much! (I'm a techy, gotta get it perfect kind of guy so research everything to death, lol) So just to confirm, suction pressure at the front pump drain, but where are the optimum (or required) locations for the a) Flo meter (I have one en-route already), and b) return...

Is there a FAQ for making those measurements and related equip? Thank you!

I meant to say that the standard pressure gauge at the top of the DE Filter @ 3450rpm (top speed), is (at this time of year where the filter is clogged and we only have about 30 days of open left): All valves OPEN (stair jets, return jets, sheer descent 18" ): 14psi (this was 9psi at the...

I was measuring the flowrate using a VERY unscientific method. 5 gallon bucket, iphone stopwatch, collecting half the waterfall and multiplying by 2. :oops: The 18" waterfall itself could be the limiting factor as it most certainly wasn't handling the full flow at 3450 RPM on the Superflo VS...

Thank you for this. So increasing the return diameter isn't going to help with the outflow, just the capacity to flow faster than I need for this purpose? The original installer cheaped out a bit on the install (which is why we're having to replace the patio). There is no MPV on the DE...

My question is, can I increase flow back to a pool water feature by increasing pipe size from 1.5 to 2" on the pool pad outlet side only and not changing anything else? Our pool was originally plumbed all 1.5" with a 18" Sheer Descent, stair jets, return jets and with a Pentair Superflo VST it...

Yes, sorry, forgot to mention that trick as well. It's still stuck. I am hoping to receive replacement parts from the US today and THEN I take the blow torch or dremel to it this weekend I guess. ;-)

I am no expert, mine is strictly a personal opinion. Bearings can sound smoother at higher speeds because the frequency of the pitch (and general motor noise) is also raised. Around here at least, we have reliable motor repair places that will diagnose pool pumps in a day or two for CDN$35. I...

I've had an issue with sticky CMP (Custom Colded Products) Spa Master Top Draw Air Controls (Gray 1") before, but now one is so stuck that trying to loosen it is also loosening the locking nut behind the fibreglass stairs it's attached to. So I am lookng for possible ideas for removing this Air...

I’m wondering how this worked out. It seemed to me like you could run the Quad DE without adding DE (or after backwashing it significantly) but with the cartridges in and then after the algae is SLAM dead, clean the filters by hand, re-charge say half DE to start filtering dead algae, backwash...
