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.
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.
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.
