SOURCE: my pentair controller will not shut the filter pump off

Chances are that you have a bad relay, but the problem could be the main logic board. If there is a spare relay in the box switch all the wires from the pump relay onto the spare. Remember to shut off the breaker, and also you will need to change the wires on the top of the relay too, or you will have to do some reprogramming.

SOURCE: replace the grids in my Pentair NSP60 filter

Remove the band clamp on the tank and start the pump for a second or two untill the top pops then open the air bleed to drain the tank and pull top off. There will be two nuts that you remove from the long studs that come through the top manifold . Once you remove these gently turn the manifold back and forth while pulling up on it. When you get it off rock the grids and pull them up. You will need a garbage handy while you do this to put the caked D.E. in. When all the grids are out you acn pull the bottom frame out. and rinse the base by turning the pump on till the filter base fills then shut the pump off and open the backwash and rinse with a hose while it drains out. You can rinse the parts while you do this if your quick enough. If you used a five gallon bucket to put your old D.E. in Turn the manifold upside down and then assemble with your new grids. Seven are the same size one is smaller that one coresponds with the stand pipe and the bottom has a notch for the same. Whild upside down the grids will line up with the bottom frame a lot easer than when righted. with the steel bolts in their holes carefully tilt the assembly to start the nuts on the through bolts. When they are hand tight rite the assembly and finish tightening it all up. At this point you can lube the stand pipe "O" ring and install a new tank "O" ring. Set the assembly back in the tank and replace the top faceing the same direction as when it came off. Replace the tank band clamp and tighten evenly one side then the other if you have two bolts on it till the coils in the springs touch each other. If it's old enough not to have springs on the bolts tighten them till they squeek.Start pump, bleed air out of tank, ck for leaks and recharge the filter. If you take apart like this once a year and clean the grids or after alge problems you should get eight or ten years from the grids. Good luck!

With the top off close the air bleeder then turn the pump long enough to fill the tank then set the top on the filter. As the water tries to drain to the pool the vacume it creates will pull the top tight. While you have this suction place the band clamp and start to tighten. You might have to try this once or twice but I'm sure it will help. Good luck.

SOURCE: Pentair sm2-pp3 valve, triton II filter. Upon

Lots of sand? You may have a broken lateral in your filter.

To repair, you will have to remove all the sand from the tank to physically inspect.

Might you have changed the sand this year? (top 1/3 needed to be changed every 3 to 5 years normally) If you changed the sand ... did you put water in the filter tank first? If not ... there is a good possibility you broke a lateral (a small pipe with slits in it) when you put the sand into the filter.

It could be that you have too much sand in the filter. Check the owners manual for the clearance - top of sand to top of filter.

Thanks for your interest in

SOURCE: Pressure is causing filter top to 'blow off',

When this happened at the job, I found out someone didnt open the pressure side shut off valve.

It may be time for your to replace the inspection port and/or change the sand. In addition to the closed valve, the threads were worn from much use over many years of service in my case.

The pressure should run about 15 to 20 in this filter ... what is your pressure?

No air pressure inside pool filter

it should be ambient air pressure inside as well as outside the filter. Are you saying that there is a vacuum equal to that of outer space in there? :)

Total alkalinity can be lowered by adding muriatic acid or sodium bisulfate. Acid may be added in doses of up to 1 quart per 10,000 gallons. Total alkalinity tests and further required additions of acid can be made every 2 hours.

it sounds like your valving for the return water is set wrong. check to make sure that some water will return to the spa when the pool is running. It's a valving problem more than it is a filter problem.

Pump problems?

Their can be a number of things.. Is the pump priming. Hopefully it did prime. what usually happens after running for awhile, with no cool water coming in. The water inside the pump basket starts to heat up, then the tubing turns to brownish on the input side of pump and exhaust side. (you could have air leaking in throught the input side, which could result in the pump never priming) Or if it is priming and no pressure (can mean your empellar is clogged up)
