PRESSURE GAUGE With DIAL HAYWARD OEM BACK MOUNT
How do I use this gauge? It seems like I'm supposed to set something?
Hello, If the pressure raises in the filter you will need to lower that. Here is a great article on how to read a pressure gage.http://www.inyopools.com/Blog/use-pool-filter-pressure-gauge-air-relief/
Less than 1 hr
With pump turned off unscrewed old gage noting how many turns it took. New gage came with nylon tape on tapered screw section. Screwed new gage in place. Used same number of turns original gage used. Started pump, bled air and all was OK..

Pliers, Adjustable Wrench, open wrench of the appropriate size
First, a relatively accurate pressure gauge will give more accurate pressure readings, which IMO are necessary for both diagnosing problems with one's pool (both equipment and other things), as well as regular maintenance... there are numerous articles in the forum area on this.
Changing a pressure gauge on a Hayward DE type filter is really simple (compared to, say, changing a pump).
*First: turn off the pump, and be sure it will not come on during your work (best to turn off the circuit breaker).
*Next: open the relief valve on the top of the filter for a moment to take pressure off the filter.
*Then: using a suitable tool (open end wrench or thin profile pliers), remove the existing pressure gauge (remember: righty = tighty, lefty = loosey... grin).
*Then carefully start the threads of the new pressure gauge into the opening, being careful to keep the pressure gauge straight as you start the threads, so you will not 'cross thread' the threads (cross threading means the threads are not engaging straight, they will chew up each other if that happens, resulting in the need to buy more parts... bad thing... grin).
*Tighten the pressure gauge enough to stop any leaks. It is not necessary to get this too tight, simply get it tight enough to stop leaks.
*Reset the circuit breaker, turn the pump on, and open the air bleed to get the air out of the filter.
You are ready to read more accurate pressures.
Couple of things one can do with a pressure gauge:
*When the pressure gets too high, time for a backwash
*Within bounds... one can use the pressure gauge to help them get a rough (rough) idea of TDH (total dynamic head) for pump selection. Note on this, it is better to get a more accurate number by either carefully measuring the plumbing, or getting a vacuum/pressure gauge and testing at the 2x pump ports.
Hope this helps!
Now it is time for a swim...
