- Swing Check Valve True Union
Terrible By Chris on 5/30/2014Chris wouldn't recommend this product to a friendI installed this check valve about a week ago and since then I've tested it many times. Does not work as advertised. The valve for some reason continually opens and closes making a load vibration noise. It only slows the water flow. Maybe it needs more time to wear in.
Awesome!! By 120reef on 1/11/2014120reef would recommend this product to a friendLooks and works awesome!
Didn't work for me By Brad on 11/23/2013Brad wouldn't recommend this product to a friendI used the 1 inch version of this valve between my display tank and return pump. The valve worked fine for a few weeks then started acting up when I was shut the pump off for feeding. The flapper would bounce on and off where it was supposed to seat. Not only did this mean it wasn't stopping the siphon from the tank, but also sent vibrations though the pipes and sump. This would continue until I would lift the loc line out of the water to break the siphon. I tried cleaning the valve even though it was not visibly dirty, and that would make it work correctly for about 2 days. I called customer service, they had no other suggestions but offered to send me a new one free. New on came and had the same problem.
I have now switched to the spears true union check valve and it has worked fine for over a month now. I gave the product 2 stars instead of 1 because a friend of mine uses this valve and it has given him no issues. I recommend spending a couple more bucks on the spears valve.
Great for return By G hoover on 11/18/2013G hoover would recommend this product to a friendUse inline for return pump. Works perfect when I shut pump down for maintenance . USE THIS OR HAVE PROBLEMS
Great quality By Yunier on 8/6/2013Yunier would recommend this product to a friendReceived fast and works great
Great Check Valve By Warren on 4/25/2013Warren would recommend this product to a friendDoes not interfer with water flow at all like some other check valves. With this being a union, it keeps you from having to add a union and a check valve. Saves space.
Works well By Dan on 4/21/2013Dan would recommend this product to a friendIts great. Have yet to have any problems with it.
Works grate By John on 4/3/2013John would recommend this product to a friendInstalled on my sump return line work grate :)
Not handling the situation at this time. By BC on 2/25/2013BC would recommend this product to a friendInstalled the check valve. Went quickly after I finally got all the parts to mate it to 3/4" vinyl return line. The main reason for the install was to prevent backflow to sump when switching of return pump. Didn't work, just slowed the backflow. Haven't had a chance to uninstall and take apart to see why the valve isn't stopping backflow but intend to in next couple of day.
Needed to upgrade the O-rings on the 2" valve By Frank on 2/9/2013Frank would recommend this product to a friendI normally do not write reviews but for this product I feel I should as it has a flaw in the design that is pretty easy to fix. They used a standard O-ring to seal the upper and lower union. I have my check valve hooked up to a Reflo Hammer head. and that pump created too much pressure for the O-ring and no matter how much I tried to tighten the union the unit would leak. I built in redundancy on my system so I have two units in series. Both units leaked in the same place. at the bottom union where the back pressure is greatest right before the swing valve.
I replaced the standard O-ring with a double seal O-ring from McMaster-Carr part number 90025K393. This took care of the issue and the leak is gone.
for lower pressure systems I am sure the standard O-ring is fine. But if you have a high pressure system that O-ring (sized to fit your valve you will have to measure yours and order the correct O-ring the part number I posted will only fit the 2" valve) will fix your leak.
I would recommend this unit, but I gave it only 3 stars as the manufacturer should just put the right O-ring on the valve. they are practically the same cost.
does what it does By chi on 11/10/2012chi would recommend this product to a frienddoes what it is suppose to do and has not failed on me yet when i lost power from super storm sandy
Works well By Wes on 8/16/2012Wes would recommend this product to a friendI have been running this valve for 3 months now with no problems at all. easy to maintain. Highly recommend.

hi from where do you get the measurements to know the size is the check valve?
Bulk Reef Supply Hi Santiago,
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
Bulk Reef Supply Hi David,
It can be installed horizontally.

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.
Bulk Reef Supply Hi Lloyd,
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.
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.
