Question about Hayward 3/4hp Super Pump Inground Pool Pump 115/230 Volt # Sp2605x7

1 Answer

Pressure gauge at maximum

I have an Hayward vari-flo. When on Filter, the pressure gauge is always at maximum, but when on backwash, the pressure gauge is a couple of lines lower than maximum.

    How is the water pressure coming back into the pool? Is the water pressure strong?

    When you turn off the pump, does the gauge return to zero? What is the maximum on the gauge? Perhaps you just need a new gauge that goes up to 45 or 60 psi.

Do you have a 'Earth' (dirt) filter system.

If - yes - these get block v-quickly (v-quickly!)
* Try to minamize 'vac'ing your pool, (or clean filter each time after 'vac'ing Or Vac on waste setting)
* Use pool skimmer box filter socks.

Hayward vari flo valve


Does it filter? Does the pump have full prime? I'm not clear about how when the valve is put in the backwash position nothing happens.

Hayward sand filter


Reference your pressure gauge as the 12:00 position. Going clockwise-
12:00 is Filter, normal running position
2:00 is Waste, water goes from pool and exits the waste line, bypassing filter.
4:00 is Closed, used only when servicing equipment
6:00 is Backwash, reverses water through the filter and goes out the waste line.
8:00 is Recirculate, water bypasses filter and returns to pool.
10:00 is Rinse, water goes through filter and exits to waste line, used briefly after backwashing to clear sediment from filter.
Note that the "pointer," not the handle that you grab, indicates which setting you are on.

What i she sequence when backwashing---Backwash - Rinse - Wash ? I have a Vari Flo


Backwash until water in the sight glass is clear, shut off the pump and change the valve setting to rinse, turn the pump on for a couple seconds and then back off, change the valve setting to filter and return to normal operation. NEVER move the valve handle while the pump is on.

Too much pressure in sand filter


IF your filter is really the EC75 that's listed in the heading, then it's not a sand filter, its a DE filter. See link to manual:
http://www.haywardnet.com/products/Manuals/pdfs/Manual257.pdf
If this is not the correct number, then you can find the correct manual on their web site. So did it have a multi-port valve already? or did you install it. IF it is a sand filter then there is something plugged inside the filter (small fingers on spider?) If that's the case locate the manual on their web site and follow the assembly insturcitons.

How to open pool, fill sand filter with water?


I happen to have a copy of the users manual for this pool filter. These are the instructions for operating your filter.

1. Be sure correct amount of filter sand media is in tank and
that all connections have been made and are secure.
2. Depress Vari-Flo control valve handle and rotate to
BACKWASH* position. (To prevent damage to control valve
seal, always depress handle before turning.)
3. Prime and start pump according to pump instructions (be
sure all suction and return lines are open), allowing the filter
tank to fill with water.
WARNING: ALL SUCTION AND
DISCHARGE VALVES MUST BE OPEN WHEN
STARTING THE SYSTEM. FAILURE TO DO
SO COULD CAUSE SEVERE PERSONAL
INJURY.
Once water flow is steady out the waste line, run the pump for
at least 2 minutes. The initial back-washing of the filter is
recommended to remove any impurities or fine sand particles
in the sand media.
4. Turn pump off and set valve to RINSE position. Start pump
and operate until water in sight glass is clear—about 1/2 to 1
minute. Turn pump off, set valve to FILTER position and
restart pump. Your filter is now operating in the normal filter
mode, filtering particles from the pool water.
5. Adjust pool suction and return valves to achieve desired
flow. Check system and filter for water leaks and tighten
connections, bolts, nuts, as required.
6. Note the initial pressure gauge reading when the filter is
clean. (It will vary from pool to pool depending upon the
pump and general piping system). As the filter removes dirt
and impurities from the pool water, the accumulation in the
filter will cause the pressure to rise and flow to diminish.
When the pressure gauge reading is 8-10 PSI (0.55-0.69
BAR) higher than the initial "clean" pressure you noted, it is
time to backwash (clean) the filter (see BACKWASH under
Filter Control Valve Functions.)

Recommend backflush pressure of a hayward pool filter


After you have backwashed your filter until the site glass run clear. Go to rinse mode for 30 seconds. Make note of the filter pressure. Don't backwash until the pressure goes up 10 psi!! It is important not to backwash too much. As pressure climbs the sand filter actually filters better.

Hayward vari flo valve


If the spider gasket in the vari-flo valve is no good, you will usually notice one of two problems.

1. Water leaking out backwash port while filter is operating.
2. Valve positions are really difficult to change.

The way to check this is if you are able to move one or two of the "spokes" in the gasket freely(out of the track it sits in) once the top of the valve is removed.

If so you need to replace. The gasket is usually held in with a silicone sealant. Once you remove the old gasket. You will need to scrape any remaining rubber from the track it sits in. I've found that a brass brush from a pluming supply store or home depot along with a flat head screwdriver is usually enough to do the removal.
I always used Permatex Blue RTV sealant on all valve jobs. It can be found at any auto parts store or sometimes Walmart. Follow the instructions for curing. Once cured the gasket is good as new.

Pool sand filter noisy only on filter setting and no pressure , but if you bypass the filter the noise goes away and there is pressure


Something is stopping your water flo before the filter otherwise you would show pressure on the filter guage. The only thing that I can think of would be if you had taken your backwash valve apart and reassembled it in the wrong position. Ether put the handle on backwards or mounted the top out of place. Hope this helps, good luck.

Check to make sure the plumbing is in the correct inlet/outlet on the valve head. Sounds like it's plumbed backwards. Inlet is from the pump, out to pool...
