OK, well I figured I have spread this concept all over many threads and should probably put something together to explain things a bit.
First off, some history. My Liquidator with it's 1/4 inch inner diameter line (ID) was not able to fill fast enough to get me much past a flow rate of "2" on the flow meter. I attributed the low fill rate with the low amount of pressure I have on the output from my filter. I have a system that flows fairly free. It sits around 8 psi most of the time.
So having a science background and realizing I was loosing some pressure on the 1/4 inch line I opted to fine out how much.
(I copied this from another one of my posts so as not to have to type it all again)
@ 1.5 GPM 1 ft of 1/4 inch line will drop around 1.27 PSI of pressure
@ 2.0 GPM 1 ft of 1/4 inch line will drop around 2.21 PSI of pressure
@ 1.5 GPM 2 ft of 1/4 inch line will drop around 2.54 PSI of pressure
@ 2.0 GPM 2 ft of 1/4 inch line will drop around 4.41 PSI of pressure
@ 1.5 GPM 3 ft of 1/4 inch line will drop around 3.81 PSI of pressure
@ 2.0 GPM 3 ft of 1/4 inch line will drop around 6.66 PSI of pressure
Do you see how it sharply jumps up.
Now lets look at some larger stuff
@ 2.0 GPM 3 ft of 1/2 inch line will drop around 0.188 PSI of pressure
@ 2.0 GPM 3 ft of 3/8 inch line will drop around 0.814 PSI of pressure
@ 1.5 GPM 10 ft of 1/4 inch line will drop around 12.71 PSI of pressure
@ 1.5 GPM 10 ft of 3/8 inch line will drop around 1.57 PSI of pressure
@ 1.5 GPM 10 ft of 1/2 inch line will drop around 0.368 PSI of pressure
So with all the numbers as evidence that I was loosing almost all of my 8 PSI of pressure through the 1/4 inch line I opted to try something simple. Bigger is better Well most of the time.
I ordered the following parts from US Plastics (Here)
62175 Male Adapter Nylon Fitting 6 $0.66 $3.96 <- Order 8 if you have an AG pool
64197 Female Adapter Nylon Fitting 2 $1.10 $2.20
22126 Buna-N-Seal/End Conn. 3/8" HB 2 Way Ball Valve, 3 1/4" x 1 3/4" 1 $6.97 $6.97
22231 1/4" FNPT Polypropylene Check Valve 1 $5.87 $5.87 <- Order two if you have an AG pool
I purchased some 3/8 inch ID Vinyl line from HD for use in this project. The black line I had lying around and I actually prefer it. I'm pretty sure it's the same Tygon line many have mentioned , only 3/8 ID instead of 1/4 inch. You may also want some small cable ties.
Here are some photos
Part # 64197 is shown here on the outlet side of the LQ
Same part # on the inlet side. Use a good amount of pipe dope or Teflon tape.
This check valve (#22231) along with two part # 62175's on the inlet side. It has way more flow then that supplied with the LQ. It can also be taken apart to clean (if needed). Order two and two extra 62175's if you have an above ground pool.
You will need a 1/4 inch NPT pipe tape to do this right. This is the suction side of the pump going to the outlet of the LQ. Yes I like to paint my PVC black. Course I could have cleaned up the pipe dope a bit better
This one is right after the filter. I get some major flow through the 3/8 ID line.
The control valve, it looks exactly like the one supplied with the LQ...only larger. Part # 22126
The original flow meter with two #62175's screwed in to it with some pipe dope.
The inlet and outlet lines. Time to repaint my pipes...they looking pretty bad.
The LQ itself. Yes I painted the bottom white. It helps keep most of the sun off the chlorine. Not that I get too much directly on it.
Last but not least I did some quick mods to the floats. By using the point of an exact o blade with the floats removed from the LQ and disassembled I carefully rounded out 4 holes total in the floats. Two on the top sides and one each on the sides. You can see all but one hole here. Be sure not to hit the tube in the center. I would highly suggest not using a drill unless it's a drill press and you watch it closely.
If anyone has any questions, please feel free to ask.
I am now able to smack the float ball on the top of the flow meter actually making it thunk. My flow rate would be something like an 8 - 10 if it went that high
Another nice side effect to all this larger hose and increased flow, if I should get any "White stuff" who cares. The passageways are all so much larger it would be unlikely to block them. If I did get some white stuff, I can just blast it away with one turn of the control.
