Hurlcon sand pump seems to pump water out of the pool. It's like it's on backflush all the time. Anyone had similar problems?

Either your Filters Valve setting is in the wrong position, or your filters valve needs to be rebuilt or replaced. (valve diverter or and/or valve gasket)

How do I install a diverter valve on a whisper flow pump

You must be using the wrong terminology as there is no diverted valve to a Pentair,purex, Pac_fab whisperflow as this a model of a pump. There a're diverted valves in a 3 way valve on the plumbing in front of the pump or in the skimmer to the pool and or spa. So feel free to email me back with further info and I'll be happy to walk you through it. Hightidepools@gmail

Spa emptyed into pool and the jets are still working what do I do to fill the spa again

If use a diverter to move the water from pool to spa and back and forth then you can use that to fill the pool which is what I suggest doing otherwise you would use your hose to start fresh unless there is plenty of pool water.

Water running through the backwash valve when in filter position

Open the valve and replace the "wagon wheel" looking gasket that sits below the diverter.

Why does the spa empty when the pump shuts off? just got a pool with an aqualink RS4 and no manual to look at. thanks

This problem can be caused by a couple things. the two most likely culprtits are either the absence of check valves and or incorrect actuator settings when the pump shuts down.

Your spa is most likely higher than the pool. You most likely have a spill over (waterfall) feature from the spa into the pool. This is so the spa water can be recirculated in pool mode. One of your actuator valves may be slightly off closed position in order to allow spill over in the spa, or you may have a dedicated overfill pipe in the circuit to feed water to spa in pool mode.

Whichever spill over piping you have set up, when the pump shuts down, water from the spa ( higher level than the pool) will backfeed through the overflow spa circuit, back through the pump and into the pool through either drain or return. Effectively rendering your spa level the same level as your pool.

To fix this problem, simply install check valves into the spa runs and as a secondary measure put one into the pool return run ( the run that feeds water to pool).

This will insure that when the pump shuts down, no matter which position the valve actuators may be set, water can not back feed through the pump circuit from spa to pool.

My jacuzzi keeps emptying into the pool when the pump switches off and then refills from the pool when the pump comes on - do you know what the problem is?

I agree it sounds like a check valve. if the water in the pool matches the water level in the spa, or drains all the way (depending on how far the spa is raised) then it is the valve before the pump, but if it goes down to the jets (and not any further) then it is a check valve or valve on the retun side of the plumbing ( after heater or chlorinator).

Operation my Pentair 2" Pvc, 3 Way Lube Free Diverter

Every valve is unique to the system in which it is plumbed. You cannot specifically say that there is one way to turn a valve and then apply it to your situation. So, there is a way to determine what you need. Three way valves should be plumbed with the water flowing into the valve at what one would recognize as the "leg" of a letter "T".

Assuming the valve is plumbed this way, the source of flow to the other ports is either from the pool/spa or to the pool/spa. for a valve plumbed in front of a pump, the direction is from the pool/spa. For the other 3 way valve, it is to the pool/spa.

The easiest way to detemrine flow is point the valve handle to one direction. Keep in mind that water flow travels under the valve handle. So, if you see water flowing from your skimmer at the pool, the direction the valve handle is pointing is FROM the pool. The opposite port of the valve (180 degrees) is FROM the spa. Do the same for the other valve. If water flows to the spa with a jet action as opposed to a small trickle, you have directed flow TO the spa.

In general, both handles will be pointed in the same direction. At times, they may not so that is why you need to determine flow and then label thew ports.

It is not wise to run a system with the flow not set for POOL suction/POOL return or SPA suction/SPA return. Having the valves in opposite direction can result in an elevated spa draining to a level equal to the pool.
