- Swing Check Valve True Union
Check valves allow one directional water flow and are used to prevent back flow and siphoning. They are commonly used on return pump outputs to prevent water overflowing the sump in the event of a power outage, pump failure or maintenance.
- Slip x Slip
- True union connection can be screwed and unscrewed for replacement of maintenance.
These are among the highest quality check valves to be found. Relative to other types and manufacturers of check valves, there is minimal pressure loss.
The true union check valve is specially designed to be disassembled by unscrewing the nuts in line leaving the tail pieces solvent cemented to the pipe.
This true union allows you to remove the body for repairs, or cleaning, even providing the opportunity to change the body or spring.
The golden rule of plumbing is that every job takes three trips to the store. While this can be frustrating locally it can be much worse when shopping online. Being short a fitting or two can delay a plumbing project for days. Here are some quick tips to avoid this.
- Plan your plumbing on paper
- Don't skimp on unions. Unions allow for easy breakdown and maintenance as well as remove the need for precise elbow placement. Use them as often as possible.
- When in doubt order extra. We happily accept returns for a full refund (less shipping) on all unused fittings within one month of purchase. A few extra bucks in return shipping is less frustrating than a project delay.
Check Valve FAILED!!! By GroundedIVLife on 9/7/2018GroundedIVLife wouldn't recommend this product to a friendFailed to do what it was intended for... Had a power outage this check valve was supposed to stop my sump from overflowing but DID NOT!!! 40 Gallons of water soaked and ruined my carpet.
Easy install works fine By Kenneth on 4/11/2018Kenneth would recommend this product to a friendBought this to add to my 1" PVC return line to prevent back flow into the sump. So far so good, just be sure that you calculate the resistance into your head pressure, I assumed it adds about 1'.
The valve leaked By Energy Guy on 3/25/2018Energy Guy wouldn't recommend this product to a friendI was going to use this valve in a vertical position, but it leaked, not a lot, but it leaked and I need a valve with no leakage because of where my aquarium is installed. The flapper design doesn’t look like a good design. I ordered and installed the Spears True Union check valve and it worked great. The reason I gave this a two star rating instead of a one star rating is you could use this valve if a small amount of leakage is OK and you want to save a few bucks.
Don’t work. Flooded stand By Chad on 2/12/2018Chad wouldn't recommend this product to a friendThis thing doesn’t work worth a crap! The one I have mounted in the horizontal position doesn’t close all the way and it floods my sump and stand
Leaks By DaveG on 2/3/2018DaveG wouldn't recommend this product to a friendReplaces the old one because of it leaking. Replaced it with the exact on and still leaks!!
They work but probably not the best option By Trent on 1/22/2018Trent would recommend this product to a friendThese hold back probably 99.9% of the water when you shut off your return pump but some leeks through. If you are facing a situation when you power goes out for more than a few hours you better have a lot of room in your sump. I put a ball valve below it so I could turn it off if that is the case.
Works Every Time By Brenton on 9/16/2017Brenton would recommend this product to a friendI have three of these and they work without fail. Simple to install. I put all of mine at the start of the pump so they are submerged. Never cleaned but I can see into them and there is no build up.
Leaks By Glen on 5/31/2017Glen would recommend this product to a friendLike many others say the o-rings are junk. Before you install this go to homedepot and find suitable replacements for them. Other that that it's good for the price. Does vibrate some when I go to standby for feeding/ maintenance however it does it's job.
needs better O rings By jovahn on 2/9/2017jovahn would recommend this product to a friendThis product i would still recommend to a friend because it does works , however i would have to tell them to replace the O-rings with better ones because after i replaced mine I no longer had a leak. BRS i see there are many others who have had this same issue please fix the problem.
works as expected By Alex on 12/30/2016Alex would recommend this product to a friendworks well to slow the back drain of my tank and allow for pump maintenance with out the rush of water back to the sump when turning off system.
VIBRATION AFTER SHUTOFF! By Anthony on 11/30/2016Anthony wouldn't recommend this product to a friendValve is vibrating (opening and closing repeated) after shutting down making annoying noise for a long time. I assume that it is due to water pressure but I consider this a failed design.
Needs beefier O rings By Ian on 10/12/2016Ian wouldn't recommend this product to a friend1" valve leaked profusely at both connections. Replaced stock O-rings (angle hair) with beefier ones (thick spaghetti) and it works fine. Not sure why I got such weak rings but just looking at them they barely protrude from the valley where they sit so I'm not surprised they failed. Otherwise this is a quality product.

Is it possible to get a True Union Utility Swing Check Valve in 1/2 inch, threaded?
I have the flexible 3/4" vinyl tubing for the return line, will I be able to use this 3/4" swing check valve for my setup? thanks.
The swing check valve has slip PVC connections intended to be glued into rigid pipe. It won't connect out of the box but you could use some barb x pvc connections to add barbs to the check valve.
Hi from where do you get the measurements to know the size is the check valve?
I am not sure that I understand your question correctly, but the size listed on all fittings is the nominal size. It isn't a literal measurement but a size that represents the fittings compatibility. For example a 1" gate valve will fit a 1" pipe, will fit a 1" check valve, and so on. Even though none of them actually literally measure 1"
Hello. I would like to know if this check valve can be installed horizontally? Or must it always be in the vertical position? Thanks
It can be installed horizontally.
