I want to buy a separate stand-alone pump for my 3 units (6 feet off the ground on shed roof). What size pump do I need?

There are a number of variables to take into consideration when selecting a pump: Size of your pipes, length of the run, filter pressure, back pressure, etc. but on every single water pump, flow rate and pump head are the two most important specifications. Flow rate is how much water can be moved in time period without any restriction. This value is usually given in gallons per hour (GPH). Head is how high water can be pushed by the pump at full load. This value is usually given in feet or meters. As the height you're pumping the water goes up, the flow rate (GPH) goes down. So, you want to get a pump that can get the water to six feet high and still maintain you ideal flow rate to heat the water. What I discovered is that if I push the water too fast through the system, the water does not stay in the collector long enough to heat it up enough (the water cools the collectors too fast). If you pump it too slowly, then it can't keep up with the natural cooling of the water in the pool. I'm currently using an old Intex 635T pump/filter combo that I had from an old pool. The head height for me is only 4', but that pump has no issues circulating the water. In fact, I've installed a valve to slow the water down a bit so it has time to heat up while it's in the system. The key is finding the most efficient pump for the job - don't buy a giant 2 hp that you have to regulate (and doubles your electric bill), when you can get by with, say a 1/2 HP motor that does the job just as well and cheaper. I've discovered that my old Intex pump/filter combo works pretty well and is running at about 10-15 gallons per minute and the water temperature (at the return) is warmer to the touch. You might be able to run it faster, since you have 3 panels (I have only 2). I also recommend that you put a filter between the pump and the solar panels if you use another brand of pump with no filter - any kind of debris in the water could get trapped in the solar panels and reduce your efficiency and heat. I hope this helps.

This is a booster pump, by definition should have little or no suction but boost the pressure from 1 psi to 20-40psi.I use it to boost a gravity feed from a storage tank feed by a RO to run a ice-machine that requires 20 psi to activate.If using a foot valve and primed it may pull from 6 feet but doubt if it could self prime 6 feet.

Almost any size will work, I use a High-output oil-free pump delivers 2.8 CFM @ 90 PSI and 150 PSI max operating pressure like this model BOSTITCH CAP1512-OF 1.2 Gallon Oil-Free High-Output Trim Compressor. The larger the better but this works for field use.

This an aboveground pump. If you need more tech support you can contact FamilyPoolFun at 8009502210.

I use a simple 12V air pump I got a K-mart. just get one with the different input nozzles.

Search for FLT5464 on Amazon and you will find the 4 foot ones. Order them well in advance of needing them, as they can take awhile to ship. I caution you to buy the proprietary brand. I tried to buy T5s at Home Depot and found that Hydrofarm uses a unique length. I was replacing the 2-foot ones and notes that they are about an inch off from standard. So if you try to go off-brand, make sure you write down the exact inches and take a good look at the ends to make sure you're getting the right ones.

Foot pump works on mine. The 12volt pumps don't have enough umph. You can use one to start then finish w/a foot pump.

That is the exact pump we have and we use it. You may have to get attachment tubes that match fittings, ours fit without extra tubing. We also have a solar water panel that runs with it. No issues with any of it.

I own this model and I use a Porter- Cable PCFP02003 3.5 gallon. I have never used it to build anything as large as a shed. I did lay a hardwood floor with no problems.

Do you mean a pump with 3 nozzles. Small, medium and large? If yes then you will be fine. That is what I use. You need the large one for sure, and electric is a must. And make sure to inflate it no more then 80% of the capacity. Else your chair will start to do funny things after a while.

I would check PyramidAir. They have a section that shows what connections are needed for different pumps and rifles. Hope this helps.

If you are not replacing a similar heater, then you will need 4 inch B-vent venting. A minimum of a 6 foot vertical run is required plus rain cap, roof flashing, and storm collar. Optional are the isolation valves.

I would use one off the discharge of each pump, then into a "Y" connection to the outlet. Otherwise, you risk pumping through the other pump right back into the sump. Staggering the height of the pumps would prevent both pumps from coming on at the same time.

we used a area of 27 ft x 15 ft but remember an extra 2.5 to 3ft on side for pump set up
