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.
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"
It can be installed horizontally.
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.
Use in Water feature applications By Chris on 4/22/2016Chris would recommend this product to a friendWe use these swing check valves very often in installation of water features, they are very durable!
Worth the money By Chavinpat on 3/14/2016Chavinpat would recommend this product to a friendI like the fact that the housing is clear. for visual inspection. It does not required high pressure to keep the valve opens, less head loss, comparing to local hardware store's check valve. The union makes it easy to remove for cleaning.
Great Valves By Angel on 8/30/2015Angel would recommend this product to a friendI bought 2 - 3/4" valves and they work great. Great quality and because they are clear you can see if they need cleaning. My only issue is a few weeks after I bought this my bank replaced my card because of the leak of card info that BRS had. I had no extra charges just the bank decided to changed it.
Excellent Valve By Bull Hippo on 3/23/2015Bull Hippo would recommend this product to a friendThis is the only check valve I would use , No metalic parts to corrode and poison your tank . Visual operation is assured by the clear housing. I see no appreciable reduction in head pressure. I use sched 40 pvc for tank return, Even with double anti siphon holes drilled in them , they still siphon more than I like ; exposing the tops of high tank mounted corals. With these valves installed, you will only siphon to the top of your overflow pipe or box.
This is not your hardware store check valve By Alec on 1/15/2015Alec would recommend this product to a friendI bought a check valve from Homedepot only to realize that the hardware store check valves require high pressure, therefore reduce the flow, to push the water through. This rubber check valve worked like a charm and the clear window let me see if the valve is open or closed easily!
Completely worth it. By Jason on 11/18/2014Jason would recommend this product to a friendI have 20 or so of the Home Depot check valves, they're cheap and work fine. But... they do go bad. After 15 years with different size aquariums over the years, now with 750g tank, the last thing you want is for something like this to go bad. I have been slowly replacing them with these valves mostly because you can see whats going on. I install them 'flap up' and follow the flow 'arrow' - None have failed. I will say they are a little bulky tho, but imo they are completely worth it.
Good but not perfect By Simply J on 11/3/2014Simply J would recommend this product to a friendI'm very pleased with these valves as a fail safe. However if you install them in a vertical position be careful not to drop/lose the O-Rings as they tend to fall out easily. Other then that very good product.
Good for the purpose By Daniel on 10/16/2014Daniel would recommend this product to a friendI don't have a million dollars to spend on a check valve at the moment, so I got this one. It did the job, and did it well. Having the union there is pretty nice.
There is one smidge of an issue. There's a very very small leak (allowing a very small drip of backflow). I assume this is because there isn't enough force on the flapper. BUT when you have water above and below the valve, there is enough force from pressure and gravity (creating a vacuum and pulling down on the flapper while water on top pushes it closed) zero leaking in this case.
had vibration but found problem By ayhan on 9/2/2014ayhan would recommend this product to a friendI had this vibration problem when sump pump is turned off. I was really [ticked] off.After research I found that problem is caused by pressure from water. I had installed check valve pretty close to sump pump which was mistake. Next day I have changed location of check valve and installed to closer return pipe goes to the tank. I know valve manufacturer didn't design for use fish tanks so I can't blame them for no instruction but BRS should take notes and print out for customers or send warning email about installation.
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.
