I have a Bowman Heat Exchanger. I also have a salt generator. Where do i install the check valves? I am installing two check valves?Reply
InyoPools Product Specialist Matt S. Posted: 6/9/2022
I'm not familiar with a Bowman Heat Exchanger, but generally, the chlorinator should be the last thing the water goes through before returning to the pool. The check valve should be before the chlorinator and after the heater.Reply

Can I have two check valves for my filter system? I have a salt water generator and I also lose water in my filter when it is shut off. The filter is a few feet above the water.Reply

You can have any number of valves, but you should be able to see them on your plumbing lines.Reply

I had a salt water pool installed late last year and i was told by a reputable company that opened the pool this week that i need to install a check valve after the heater and before the salt cell. They said if water backs up into the heater it could cause the heater to fail early and that any warranty claim could be void. Is this true?Reply
InyoPools Product Specialist Matt S. Posted: 5/23/2022
Yes, it is true. I'd also make sure that the heater has a cupro-nickel heat exchanger, or you'll want to install a zinc anode to prevent the heat exchanger from essentially rotting away.Reply

My pool has what looks like a check valve installed to bypass the normal control valve that regulates the return water to the pool return jets ("eyeballs"). This can not be right. If it is a check valve, this would disable the function of the normal valve. Can it be a pressure relief valve that just looks like a 1 1/2 inch check valve?Reply
InyoPools Product Specialist Matt S. Posted: 8/27/2021
The best way to find out is to inspect it or open it up. I am unable to see the equipment/plumbing, so it would be almost impossible for me to make an accurate guess.Reply

I just installed an above ground pool and I am told I need a check valve where does it need to be installed I just have a pump and sand filter on the skimmer to pump line, pump to filter line or filter to jet? ThanksReply
InyoPools Product Specialist Matt S. Posted: 8/12/2021
Did an installer or someone who has actually seen the pool said you need to add a check valve? Or is this gathered from somewhere else?You can put a check valve on the return line to prevent leaks when disconnecting the pump and filter. But you can accomplish the same thing with a plugin, the return port.Reply

This article did not tell where is the best place to install a check valve. Before the pump after the diverter valve or before the diverter valve. Please advise.Reply
InyoPools Product Specialist Matt S. Posted: 3/4/2021
There is no "best place" to put a check valve; you place it where it is applicable. You put it on a straight piece of pipe to prevent water from backflushing up the line. You wouldn't put a check valve in front of the pump because it could cause priming issues. Installing the check valve before or after a diverter valve would not affect performance.Reply

For equipment installed in an elevated placement compared to the pool, check valves should be prior to the pump on the suction side to assist with holding water for priming? Thank you.Reply
InyoPools Product Specialist Matt S. Posted: 5/9/2019
Yes, if the pump is in an elevated position, 2-feet or more above the water surface, a check valve would be a great way to maintain a prime.Reply

Hi inyo, Thanks for all the information you've put online, it's great! I've just bought a 3 speed pump that I'm going to install, but my previous pump seems to have air permanently in the lid with no real air bubbles coming back into the pool at the jets. I can't find an air leak. When I manually prime the pump water just flows down the suction side into the pool and leaves air in the top of the pump. Should I be installing a check valve prior to the pump to stop this, or should I be looking even harder for an air leak? ThanksReply
InyoPools Product Specialist Matt S. Posted: 10/10/2018
Hello Graham - If you are only using the lower speeds on your multispeed pump, the strainer housing may not completely fill with water. Since there are no air bubbles flowing from your jets there does not appear to be an air leak.If you have a cartridge or DE filter you can try the air relief valve to clear out any trapped air. But I wouldn't be too worried until you begin having trouble priming or see bubbles.Reply

Hello Rodney - You can install a check valve after a chlorinator but it won't protect your heater or filter. The purpose of the check valve is to prevent highly concentrated chlorine from flowing back to your equipment.Reply
Rodney Posted: 9/10/2018
Can the check valve be installed after the chlorinator?Reply
Inyopools Posted: 12/19/2017
Dale - Even though the Salt Chlorine Generator is not producing chlorine when the pump is off, there is a concentrated level of chlorine in the water between the SCG and the returns. When the pump is shut off, there is often a reverse flow of water back into the system. This backflow water after the SCG could damage the equipment before the SCG.Reply
Dale Posted: 12/13/2017
why is a check valve required for a salt cell generator? when power is off to both the pump and salt cell its no longer generating chlorine. i understand the need for an erosion chlorination device where concentrated chlorine can be produced after the system is powered down, but a salt cell doesn't produce chlorine after the power is off. Please advise why additional pressure drop should be added to the plumbing via a check valve, if it doesn't really add value in a salt cell system.Reply

Tom murphy - Yes, a check valve can be mounted in any position. They are operated by water pressure against the flapper of spring.Reply

Can the check valve be mounted in a hormonal position ?Reply
