The motor bearing is making the squealing noise. It can be replaced without buying a new motor. Most electrical repair places can do it. It's probably leaking because of the play in the shaft because of the worn bearing. See if it still leaks when the bearing is replaced.

hi,
As you said the elecrtical connectoins made by you is correct. But the pump is not getting power from the pannel board to which you connect the power lines. If the older pump burned out then it can make some trouble to the pannel board also. Check if there is any contactor relay in the pannel board, it will be there. If so you have to check the its condacts through which the pump gets power. There is a chance of burning of the contacts of the relay when the older pump burned. If so you have to replace the relay also.
ok

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.

you can go to your local pool shop and they can get you a replacement label...and there is a placement notch to make certain you put it on correctly.

If you have the valve in the Filter position and it is still leaking water out the backwash line, the problem is the Spider gasket inside the valve itself. However, the valve that usually comes with the Sand Dollar filters has the gasket glued to the Diverter, and has to be replaced as one piece, sorry about that!

If you have a manual on the filter, go to the parts page dealing with the valve. If you do not have a manual, the link below will take you to one online:

The part that needs replaced in Item #8. What you will do when you get the replacement part is to stop your system, close any valves to stop the flow of water so you do not loose too much. Then you will open up the Air Release Valve and release all the pressure in the filter. Pentair usually recommends that you wait at least 30 minutes after this to make sure there is no presure in the tank. Once this is done, you will remove the screws holding the top part of the valve to the bottom, place the screws is a safe place so yo do not lose them - did that once!- and pull the handle portion up, as a single piece.

Place the top part on a flat surface, and remove the Handle Screw (Item #3) while holding down on the top of the valve. This will help keep the spring in the handle from popping up on you! Slowly raise your hand to allow the spring to expand, no parts will go flying this way! (did that one too!) Then just pull out the old Diverter and replace it with the new one. Reassembly is a bit difficult because of that spring, but once the Handle Screw is in place, it is pretty easy. You DO NOT need to lube the gasket/diverter, so you just line up the diverter sections with those in the bottom of the valve and replace the screws. Just in case, the WASTE position is always OVER the Waste Port on the valve.

If it is only a pinhole it should be an easy fix. First dry the unit thoroughly, the drier the better. Then use superglue gel to patch the hole from both sides.You may wish to smooth the glue for aesthetics just make sure you leave enough so the glue can hold to the interior under pressure. The gel will dry overnight and is non-toxic. Larger holes or cracks would require a plastic welder or applying fiber glass.

If these Hayward pool filters are leaking DE back into the pool, there are a couple things that you will want to check. Check for loose bolts on tube nest plates and tighten them if necessary. Make sure that you don't have a worn or loose fitting diaphragm gasket and that there are no rips and holes in it. Replace the gasket if any of these is the problem. Check for openings or tears in one or more Flex-
Tubes and replace them if necessary.

Hi,
Check the pump for an obstruction... the bearing that they are not seized up and the motor that it turns freely...other then that the motor is no good...
