Question about Pool & Spa

My hurlcon multi media pressure gauge is reading 245kpa does this definitely mean media replacement is needed?

Pressure gauge is reading 245kpa, i have never seen it above 20kpa and it is usually 5 or 10kpa. Is it worth trying a backwash, or is this a clear sign that the media is due for replacement?

SOURCE: No pressure at all on pump gauge

Without knowing your pip and valve layout, it is difficult to assess the stiuation, but it sounds to me as if either a valve that lets the water into the filter is shut, or the filter is full of air and needs to be primed. On some models if you loosen the top ring until the water fills the chamber and starts to overflow that takes care of the problem. But if you cannot tell by looking at the layou if a valve that should be open is closed, or don't know how to prime it, don't run the pump until they can come back.

SOURCE: sand in backwash

You need to replace the seal in the head unit of the filter.. The sand should be replaced every three years or buy a cleaning solution.

You probably have too big of pump. It is pushing the finer stuff right back into pool. Try adding a clarifier. Don't backwash either until the pressure goes up.

Why does the filter basket never seem to catch anything and it never reads to need to be backwashed...but the water is still not clear....what are we doing wrong?


Because of the size of the filter - 18", I would presume this is an above ground pool?

  • Do you have a skimmer?
    • If so, put some leaves, larger organic debris, etc. into the skimmer. They should end up in the basket of the Hair & Lint Pot!
    • That would prove your question to be either working or not.
  • If you don't have a skimmer, then you have a suction port in your pool.
    • Let that suction port suck some larger debris that would stay in the basket. Again, you will prove or disprove, whether debris is getting to your pump basket (Hair & Lint Pot Basket).
How long has your pump & filter been operating?
How long do you let your pump & filter run per day?
  • It should run at least 8 hrs per day.
  • If cloudy, you should run continuously until clear.
How long has your water been turbid/cloudy?
  • Use a clarifier, Natural preferred, like SeaKlear, daily at recommended dosage, until clear
What is the pressure?
Are you saying that it is the same pressure as Day 1, has not climbed at all?
What do you mean: Does not read that backwash is needed?
What in your understanding is: "Time to backwash the filter"?

You should know the "Starting Pressure" of your Sand Filter!
  • When sand is absolutely clean & free of any grime and sticky residue.
    • Just added media, when just installed is the best time to make a note of the starting pressure on a working pressure gauge.
  • When the pressure rises 8-10 lbs. over starting, time to backwash!

Tip

Backwashing A Sand Filter with A Push/Pull Slide Valve or Multiport Valve


Lots of people are first time pool owners and pool professionals forget to teach these "newbies" about the simplest aspects of pool ownership.

One of the biggest questions we receive from new homeowners is "How do I go about backwashing my sand filter exactly?"

It doesn't matter if you have a Hayward, Pentair, Jandy, Sta-Rite or any other number of Sand Filters on the market they all utilize the same basic valves for backwashing; a push/pull slide valve or a multiport valve.


To backwash with a multiport valve:
1) Shut off pump motor.
2) Press down on valve handle, rotate valve from FILTER to BACKWASH position.
3) Roll out any backwash hose or open any waste line valves.
4) Open air bleeder assembly on filter, and turn pump on.
5) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
6) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
7) Shut off pump motor and move multiport valve handle to RINSE position. Run on rinse for 15 - 25 seconds.
8) Shut off pump motor and move multiport valve handle to FILTER position.
9) Turn pump back on and note lower pressure.
10) Roll up backwash hose so the dogs use it as a chew toy.


To Backwash a sand filter with a slide valve:
1) Shut off pump motor, roll out backwash hose.
2) Twist to unlock plunger T-handle, push or pull(depending on manufaturer) the plunger 2" - 3".
3) Open air bleeder assembly on filter, and turn pump on.
4) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
5) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
6) Shut off pump motor and push T-handle back down into locked position.
7) Turn pump back on and note lower pressure.
8) Roll up backwash hose.

Now you are a backwash Guru!

Pump is blowing cloudy water back into pool


Cloudy water is the bane of sand filters!. I suggest letting filter run day and night. Do not backwash until the pressure rises 8 - 10 pounds above clean starting pressure. Do not try to vacuum or stir up the sediment. when water clears, vacuum to waste. Keep the hose running while vacuuming. A dirty filter is a better filter (up to a point). At a higher pressure the filter will trap more of the fine particles that are clouding your water.

Pressure guage reading 25-35 upon opening pool. backwashing made no difference.


if the pressure on the gauge does not lower after backwashing you may need to change the sand in the filter.
This happens when the sand is so compacted that it is not able to be moved around to clean the debris out when back washing.

Poor water circulation, not enough pressure to move polaris around adequaately


Check the basket at the skimmer and the one on the pump and make sure they are clear. If you have a pressure gauge on your filter does it read higher or lower than normal? If it is higher that would indicate a dirty filter and needs to be taken apart and cleaned or backwashed. If it reads lower than normal the problem may be a clogged impeller, where debris has gotten past the pump basket.

How do i get a higher flow into my pool


The low flow could be caused by a clogged filter. If you have a sand filter and the pressure gauge is reading a high pressure then turn the control valve to Backwash the sand filter until the water is clear in the waste pipe (usually for 2 to 3 mins). then turn the control valve to Rinse for about 1 min then turn the control valve to Filter.

How to use backwash to waste


When the filter get clogged the pressure in the filter increases and there is less water flow returning to the pool.
If your filter is a sand filter, when you turn the valve to backwash and turn on the pump it reverses the water flow in the sand filter to flush the dirt out of the filter to waste. Look at the window openning in the waste pipe and keep the backwashing goinging until you see clear water.
Then turn off the pump and move the control valve to Rinse, turn on the pump for a few minutes, this returns the water flow back to normal but the water goes to waste to make sure the sand filter is clean.
Turn off the pump and move the control valve to filter and turn on the pump. This mode is the normal operating mode and the pressure gauge in the sand filter will show a drop in pressure.
Some pressure gauge shows a red section to indicate when backwashing should be carried out.

Pressure gauge needle stays in max position running or not. otherwise pressure washer operates normally.


Pressure gauge is probably "sprung". Unless it bothers you, ignore it. Even expensive industrial pressure gauges fail regularly - I have seen a truck load worth of them (all brands and types) that read pressure even after being disconnected from pipe or tank, and the gauge on a pressure washer is anything but an expensive one.
