Air Leak In the Skimmer

by Vince
(Yuma, AZ)

I have a sand filter with a Caretaker in ground system.

I had an air leak and the pool wasn't turning over.

The only O-ring I knew to replace other than in the push/pull backwash valve was under the lid on the skimmer basket.

That seems to have solved most of the problem, as the pump is no longer cavitating.

However, as in the past, when the pump shuts off, water squirts out from under the lid of the skimmer where I replaced the O-ring.

I can only assume that if water is forced out then air can be sucked in.

What else can I do and any other suggestion as to where to look?

Thanks in advance for any advice.

Thanks for the question Vince

Above Ground Swimming Pool Losing Water..Running Sand Filter System..

How Do I Fix Low Skimmer Suction?

This is off another answered question:

"If you have more than 1 skimmer, you can try this, but be very careful.

Turn the system off.

Slowly close the valve you normally vacuum with and leave the other valve open.

What you're doing is closing off a valve and forcing the other one to do the job.

Turn the system back on.

If you don't lose suction or water in the pump pot, the other skimmer is fine.

Do the same, only opposite. Open both valves, then close the one you DON'T vacuum with and leave the other one open.

If you do lose suction or water flow, then the problem is the suction in the skimmer.

If you vacuum from the skimmer, this might be the problem. Either a broken line or clog.

Then it's time to call a repairman."

Your check valve, if you have one, might be worn out. A check valve is used to keep water flowing in one direction.

When it gets old or worn out it can allow water to flow the opposite direction.

Being that water will find the path of least resistance, it can end up going back through the line to the skimmer.

The posts above go into great detail on how to troubleshoot a suction side leak or loss of suction at the skimmer.

They are general tips to look over. If after checking out the links and doing the steps, if you still have issues, please feel free to contact me again.

Jandy JVA 2444 Valve Actuator..Pool Water Temperature Too High

My pool company recently replaced the Jandy JVA 2444 valve.

Since then my solar heat is going much higher than it is set for. It is set for 88, and goes as high as 94.

I have been trying to turn the temp. down from the controls in the house but I have to turn the pump off to help the situation.

Could the valve have been installed incorrectly?

Thanks for the question

The JVA 2444 is actually an upgrade from the older model of the JVA2440.

It has a newer design with easier cam adjustment, PCB and a hidden toggle switch.

It also automates any 2-way and 3-way diverter valve for pool & spa combination and those with water features.

It's also made to rotate diverters to any position.

With any kind of equipment such as this there's always a chance of it not working or being installed incorrectly.

It could possibly be that there isn't enough or too much water flow going through the system.

My experience has shown that it's either a lack or or not enough. The flow might be missing which in turn would possibly mean the unit was not installed correctly.

Having a 94 degree pool normally isn't refreshing.

I would encourage you to talk to the installer and explain the problem your having.

If everything was working correctly before and the only difference is that you had this actuator installed, I would definitely start there.

Hope this helps and good luck with your pool.

Water Emptying Out Of My Pool Through Sewer Drain At All Settings...

(El Paso, TX)

Why is the water draining out of my pool into the sewer when I have the settings to vacuum and even to filter? Are there other valves I should worry about when filtering, ex. drain, vacuum and/or skimmer valves?

Thanks for the question

A leak can be the most frustrating thing a pool owner can have, so here's what you can do. I will assume you have an inground pool being that you're in Texas. The question didn't mention any wet spots around the pool or filtration, so we'll go right to the pool itself.

These are a few simple techniques on troubleshooting a leaking pool. Mark the water level at the skimmer. You can use a piece of tape or a grease pencil.

Check the water level in 24 hours. Your pool shouldn't lose any more than 1/4" of water per day. Anything more and you probably have a leak. This test needs to be performed with the pump on, then off, each time for the period of 24 hours.

Now comes to fun part. This is where you find the location of the leak. Remember that vinyl liner pools need water in them at all times. If you have a vinyl liner and the pool water drops rapidly, you need to call a leak detection business immediately.

If the water drops below the skimmer and stops, more than likely the leak is probably in the skimmer, filtration system, or filtration piping. If the water stops at the light, it's probably the light housing.

If it drops below the light, and maybe keeps going, there may be a leak in the drain at the bottom the pool. If there are air bubbles going back into the pool through the returns, there's a leak in the suction side of the filtration system. One of the most common leaks is a separation or crack between the plastic skimmer and the concrete pool. This can be fixed with pool putty.

Pool plumbing can be a constant source for water loss. Old or worn out pipe material, age, and ground conditions are the most common.
You should have valves for the bottom drain and skimmer(s). Check around the ground. Is it wet? This could be the source and is easily repaired. If the ground around the pool and filtration system is dry and you done the above, it's probably time to call in a leak detection company.

Average cost for them could be between $175 - $250, repairs not included. Hope this helps and good luck with your pool.

Fountain Of Water From Skimmer When Pool Shuts Off

by Maureen

We recently replaced our filters in our in ground pool, never had a problem but they were 4 yrs old and kinda getting old. We emptied the pool at the same time, washed the walls and refilled it.

Now when the pump turns off we get a huge "fountain" of water out of our skimmer basket. We don't have any leaks or dripping, and as I said we never had this happen b4, any help is HUGELY appreciated, I'm going crazy trying to figure this out.

Thank you SO MUCH!!!

Thanks for the question Maureen

Many times when the skimmer lid blows off the filter is mostly full of compressed air. So now the question is where is the air coming from? Be sure to bleed the air out of the filter. The most common source of air is a suction side leak. You can also get air coming in through a vortex in the skimmer that draws air in along with the water. Check around the filter area of any wet spots, drips, or leaks.

Next, the skimmer weir can stick and form a vortex in the skimmer which allows air into the suction side of the pump. Be sure the weir is in good working order. Low water level? Keep the level between 1/3 - 1/2 up from the bottom of the skimmer.

Check the pump lid and o-ring for wear and/or cracks. If any are found you'll need to replace it. Is the pump losing prime? If it is, this could be the reason.

On many pools there is an inline check valve on the suction side of the pump, it is there to prevent backflow to the pool and keep the system primed. If the check valves fails the water begins to flow backwards causing the filter/skimmer basket to pop out and throw the lid off. Pool pumps and filters have tremendous energy when on.

The returns lines may be clogged. This can cause back pressure and a loss of prime in the pump and would show itself with a high pressure reading on the filter's gauge.

Does your multi port valve have a RECIRCULATE position? If you do RECIRCULATE it may make a difference in pump priming and running.

Does the skimmer still spout and blow the lid off? If it doesn't and everything is good you should check the filter for a clog. it could be a clogged or plugged lateral.
