The water does not go backward when you backwash. Backwashing is used to clean your filter, but the water that is pumped away from the pool is used to clean it. As long as you put it where the prime is needed, a check valve can help your system stay primed.
In the event that you had eight- I am tenth of one. As long as it remains accurate, the pipe should remain within 5 inches before and after the unit. Rather than using a 1/2" flow meter, a 3/4" flow meter would be a better choice. It would also be prudent to check what type of pump/pressure is running through the 3/4" pipe. Is it powerful enough to lift the flapper and spring on Valve with a 5" bore
In the case of flow controls that are black and have the ABS logo on them, you must use glue that is for ABS pipes. The instructions are vague as to whether primer is to be used The PVC is primed with clear primer before hitting the ABS with a quick hit of black primer. You may wish to avoid swabbing the socket too much as it will soften Red is the color of the glue can, I think. I wish you the best of

Having bought it, I am glad that I did. Having a variable speed pump takes the guess work out of it. According to the pump's wattage, I figured out that my system is most energy efficient at a flow rate of about 20 gpm, which I determined from my wattage vs. gpm vs. pump speed table. Division of gpm by watts is the formula for computing efficiency. Create a table by tuning the pump speed to achieve different gpm values, and record the wattage and pump speed for each One time per day is all that is required to circulate a pool. You can select different speeds to achieve one circulation with the smallest possible power consumption. ** I removed the return jet fitting that was 3/4" opening to check what effect it had, and it did indeed reduce the flow by 10 gallons per minute! This is being thrown away and I am searching for a large jet to replace it. It will take me a little while to determine the most efficient gpm. My guess is that it is about 30 gpm now.
The fifteenth point). The pool equipment that I recently replaced (after 15 years) was the spa jet pump, filter, heat pump, filter pump, and heater pump. It was easy to install and the only reason I took a star off the Overall rating and Accuracy is because it does not include a TDH curve (but others do for a 2" model and larger). Furthermore, their documentation appears to be a bit incorrect since they claim the Flow Meter introduces less TDH than a Swept Elbow yet they use the Swept Elbow equivalent feet (of 1 1/2" Pipe) to compare against the Flow Meter's TDH (e. g. In terms of feet of H2O) There is an error in this statement and the literature needs to be updated. It also seems that at low flow rates, my TDH is increased by one when using the Flow Meter. It took about 6 feet of water to install it (I measured TDH before and after). Please take note There are only 5 feet of 1 1/2" Pipe in a 1 1/2" Swept Elbow, so 4 feet is equal to 4 feet. There is a 6 foot loss of H2O per 100 feet. As a result, The sum of 6 x 4 / 100 is The amount of water is 224 feet.
If you have a pump that runs at variable speeds, this is a must have. My variable speed pump had a wide range of RPM, so I created a spreadsheet using flow measurements in that range. I was able to find the perfect balance between flow and energy efficiency according to the data. It was possible for me to program a schedule with 3x per day turn-around There is a small monthly charge of over $30, and this is over and above what I pay for wireless. There is such a difference in the clarity of the water. It is impossible to predict the flow rate without a flow meter. I turned over the water only once when I initially set up the pump schedule. The recommended number of times per day is eight. I can tell the water is much cleaner now. I swapped out my sand for glass as well. All is well. We have lowered the filter pressure, polished the water, and it has improved. Variable Speed pumps serve no purpose if you do not use a flow meter to get the best performance out of them. Investing is a wise move.
It does what it's supposed to do. This version was installed on an 1 PC. This is an easy DIY installation that can be done by most people. It took me 40 minutes to install as I took my time and maintained mechanics. This is my first time installing this product.
It is absolutely crucial to have flow meters like this to determine exactly how fast the This technique can also be used to calculate how long your single-speed pump should run, with a goal of getting your water to turn over at least once every 24 hours. I have no way to compare this device with any other because it works well, but I am not sure how accurate it is. Reading it can be a little challenging In order to see it clearly, it has to be viewed perpendicularly to where the red indicator is.
In the case of a variable speed pool pump, this is a very helpful tool. Earlier this year, I installed this before I replaced my pump so that I could understand the actual amount of water my old pump was pushing on a daily basis. In addition, I installed a variable speed pump and was able to get the right amount of water flowing each.
I am very satisfied with this product. Rather than estimating your head losses on paper and calculating them, it is very helpful to have a clear picture of flow. The best estimate I could come up with was *42 GPM, but it is actually Having that information is useful when estimating pump hours, etc.
It's also nice to know that changes in flow are immediately seen when valves are closed or when backwash is performed.
It's easy to install and works very well.
The flow rate is measured by putting it on the suction side of my pool pump. I had to replace my pump because the spring on which the flow reading is based cavitated when I tried to suck However, I did not get the 40 gpm-level reading I expected because I only got about 20 gpm out of it. There should be a note that it can only be used on the pressure side. As a result, now I can't return it since it has white pvc pipe glued into.
