Or is it mostly about budget and how much ease of maintenance means to you and your budget? ========================================================================= I have not seen a TDH meter. The pump is the Pentair SuperFlo VS. Is this pump a good match for the Quad 60 in the case of 6600 gallon pool? HEATER 7.5 If you have paperwork from your pool builder, this may list the amount of gallons in the pool. It takes any friction loss in the pipes into consideration. 4. The filter, pump, pipes, heater, backwash valve, return, and other accessories have an effect on how water flows throughout your system. So I tried to follow all the detailed steps (thank you! Note that PVC flex pipe is over a third more restrictive than rigid PVC pipe, shown in the chart. DE filters are a little rangy as well. Nobody hooks up pool heaters in series. Always remember to take the lowest of the maximum flow rates for sizing up your pool pump. Each line on the chart represents a particular pump horsepower. 60.4 / 100 x 7.76 = 4.69. Each of those plumbing add-ons tack on a value of feet of head to your plumbing line. One More Tip: Remember that not all horsepower pumps are equal. Add up all of the 90’s and 45’s used in the plumbing, above ground and below ground. I appreciate any help on this you may have. Larger pool filters with more surface area will have higher design flow rates, but every pool filter is different, from 30 gpm to 150 gpm, depending on size and type of pool filter. Or if you like sand filters, the J-SF24 filter (item E2708), or the Hayward S244T filter item E3313. The pool sweep is also on its own booster pump. Typically, you’re going to average 0.3 to 0.35 GPM per square foot of surface area. Discharge Pressure Required = In this example we are operating reticulation sprinklers that require 250kpa pressure or 25 metres. Am I missing something? The pumps and DE filter (hayward 60/20) are approximately 20 yards in a straight line from the pool. http://www.engineeringtoolbox.com/resistance-equivalent-length-d_192.html.
Measuring with a gauge is easily within 10%, more than enough accuracy for swimming pool pump hydraulics. He got the formula from our local energy company who provided rebates based on this calculation they provided.
70 28.6 7.76 Increasing the pipe size is always preferable to increasing pump horsepower size to compensate for excess resistance. For each 10 feet of 1.5 in. 5. This is because of the surface area inside the pipes. The Quad 60 is a large filter, very large for 6600 gallons. The Variable speed pump, or Intelliflo VS does not have the built-in sensors, and will operate at the speed you set it at, or per the program it is running. I got 45’s and 330 LF of 2.5″ pipe! Add up all of these resistances to find the total resistance in your system. Copyright © 2020 INYOpools All rights reserved. There is a meter on the market now that measures TDH…can you just use it to get a fairly accurate reading? I have Pentair SuperFlo VS Pump in my cart. There is a table of data , to calculate the ” feet of head ” of my pool. To calculate the horsepower of a water pump, check the water level in the base reservoir tank to ensure it’s full, and empty the second tank, or the destination reservoir. name James from Kenya can you send me a pdf of making a swimming pool from the beginning to end, @Matthew can you send me a pdf break down calculation of how to measure 2″ PVC pipes and 2″ fittings? Hello, I have a pool of approximately 15k gallons with 2-inch pipe. Even couplings add resistance, so try to use long, straight lengths of pipe, with as few connections and bends as possible. You can figure out the approximate feet of head using the general guidelines provided in the article. Same for check valves, or one-way flow valves, which add more resistance to the system. Two rotating Nozzels.
My pool is in central Florida. The water has to be pulled and pushed through pipes that bend and twist and it’s forced through impellers and filters, squeezed through heaters and valves, as well as lifted vertically, from the water level to the pump level. You don’t want a pump that is too powerful for your filter. Also the lift is measured from the water surface elevation of the pool, so if the pool is 6′ deep the static lift would be 3′ in your example. Thing is with 100 feet of 5 or 10mm tubing and a tall board or convenient wall you could cheaply measure this. There is no way those returns can output 60 gallons per minute. This article is very confusing and not very useful for those many of us who are subsequent owners of a home where the pool was installed decades prior. On the other hand, a Whisperflo 1-HP (purple line) will pump 80 gpm at 60 ft of head, as shown right. . Average depth is calculated by adding the deepest part of the pool to the shallowest part of the pool, and dividing by 2. I’ve got 10- 2.5″-90 degree elbows. Add up all of the 90’s and 45’s used in the plumbing, above ground and below ground. If you need to install a new pump or replace your filter, you need to calculate the system’s feet of head to determine the best fit. All the aforementioned plumbing quirks add up to more friction the water accrues as it travels. If the lines are the same size the difference in dynamic head will cancel out. ANSWER TO: In the “Dips and Turns” section, a number of 1.5 inch items have lower head than the 2.0 inch items, which seems very wrong. Also, keep in mind that the connectors, add up to anywhere from 5-10% of the entire head, depending on your pool size and design. Directional Valves – 1 ft each (3+8 / 2 = 5.5). All good? Use pump flow charts to select a horsepower to match your pool system Resistance to your pool filter Design Flow Rate. Would prefer to avoid the math. The amount of lift, and all of the pipes, fittings and equipment adds-up to the Total Resistance, measured in Feet of Head. Add up the total feet of PVC pipe in the system – Take your time with this measurement, to estimate the linear feet of underground plumbing, horizontal and vertical sections of pipe, to and from the pool. Total Resistance is made up of all the pipe lengths, turns of the pipe, and all of the equipment that the pump must pull and push water through. If you want to turn over your 20 000 gallons once in 5 hours, you will need to average at least 67 gallons per minute (GPM). MaxFlo VS500 all the way, baby! All these questions, and differing answers, and replies… Pool Filter – 10 ft (I’m an engineer and I do this for a living). Pool Volume in Gallons ÷ Turnover Rate in Minutes = Flow Rate. In the absence of a vacuum gauge, you can estimate the suction side vacuum to be something close to 1/3 of the pressure side reading. pipe. (Meanwhile, any dummy can use a bunch of 90 deg elbows.). You never want to put more pressure in your pipes than they can handle. Most people that have a 2-speed or variable speed pump run the pump nearly all the time, but on a very low speed for like 20-hrs per day, and high speed for 4-hrs per day. The result is pump stress, operating noise, and significantly higher energy costs. Yes, I mean all. 90 DEGREE 10 10 100 Filters can be a real drag on water as it rushes through your plumbing. 80 36.7 9.94, if I know the GMP pump that I need to buy why all the calculations? I want to purchase a Pentair VS Intelliflo pump. The waterfall has a dedicated Jandy pump on a dedicated line. I’d also recommend using Sweep Elbows in place of regular 90’s, again to reduce resistance.
The amount of friction loss in PVC pipe will also depend on how fast the water is flowing through the pipe. You finally make your decision on the model you want and have a hunch it will work well in your 20 000-gallon pool, but the salesperson drops a bomb on your plans by asking the simple question, “What is your feet of head?” Wait a minute, what? The downside is it takes more space (and good planning) to use the Long Radius elbows, and many people try to squeeze their pool plumbing (pump, filter, heater, valves) into the smallest space possible. But what Matthew has done, is provide a very excellent start. An 8-hour turnover rate is considered standard. skimmer or main drain, add 2 ft. of head, or 1 ft., if the piping is 2 in. The more friction, the harder the pump must work to push the water through the pipe, which demands that you go to a higher HP or use a larger pipe. To much information. Actually strike that –... It’s a new pool season and maybe time for a new pump? If two pump curves come close, choose the smaller pump. I have a 21 ft above ground pool with a 1/3hp pool pump and a 14 in sand filter. I would go for a Variable Speed pump, since they are going to be required anyway. The interior of all pumps share a few common elements, but the actual design of those elements is what differs from make to make and model to … After all, they don’t care about the efficiency of your pool system – you are paying the electric bill, not them. Looks funny right? Would an undersize pump cause this? feet in savings, which in turn, could lower the total head. It seems the article referenced above by Steven on how to determine HEAD using gauges is more useful. Using two 45’s in place of one 90 can reduce resistance by several feet of head. The higher the pool feet of head, the lower the flow rate. 047 789 9942 / 08 8988 9113 For example, If you have a Pentair SuperFlo, you may replace it with the same horsepower SuperFlo, or a Hayward Super Pump, or Pureline Prime. Approx 19000 gallon inground with 1 skimmer and 1 sidewall return. Ive decided to use 1″ black plastic pipe, snake it horizantally back and forth along my wooden pool fence. A 90 deg elbow: 8.4 eq.
FILTER 7.5 With regards to energy efficiency, it’s the amps that you really pay for, and you are correct that the larger motor will have a higher amp draw, and thus be less efficient. Every chart for 90 Degree elbow is different! Here are the flow rates for common filter types and sizes. With this configuration what do I use for the feet of head calculation for nozzles and the water valve? Is a Intex Krystal Clear 1500 GPH Sand Filter Pump & Saltwater System overkill for a small Summer Waves 10’x30″ (1200 gallon capacity)? For example, the SPX2610X15 will pump 90 gpm at 30 ft of head, with a clean filter and baskets. As we have some piping of 3″, 4″ and 6″ schedule 40 pvc.
