can with fit with Sch 40?
Question by: omar on Nov 7, 2013 11:35:00 AM
Hey Omar,
It sure can. Schedule 40 and 80 have the same nominal size fittings and will fit together.

Is this all plastic and can it be submerged in my sump?
Question by: Nick Fults on May 20, 2016 2:52:00 PM
Great question! It is all plastic, and can be submerged.

I'm plumbing my sump using a herbie overflow and want to use this gate valve to govern the overflow suction. My question is in regards to plumbing in the valve using slip or threaded connection. I like the look and security of glued in slip but given the cost of the gate valve and the fact that it's likely I change around my setup at some point I didn't want to have a glued in valve. What are your thoughts on which to use?
Question by: Chris on Mar 16, 2016 9:59:00 PM
Great question!
We typically will use slip and glue it in place and add 2 unions before and after the valve to make changes, movement and working with the valve easier. If you thread in the valve it still can't be removed easily as it will be threaded in opposite directions from either end and make removing it a bit of a process where as Unions will simplify the process. Feel free to let us know if you have any further questions!

is the sizing the inside diameter? just trying to double check and make sure i get the valve that fits my plumbing. Thank You!
Question by: Garran Harris on Apr 18, 2017 2:30:00 PM
Hey there,
All plumbing and fittings on our website are sized based on the nominal pvc pipe rating (meaning the internal diameter of the pipe). This means that a 1.5" bulkhead or coupling or union will accept 1.5" ID/nominal pvc pipe.

Hope this helps!

Full Details

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.

  • save yourself the hassle of sticky ball valves! By Nick on 3/29/2017

    at first i was in total sticker shock when i seen the price of these, needed 3 for my build and almost passed em up... SO GLAD i didnt. so much so, i convinced my buddy to get the same ones for his build. don't skimp on this piece or unions.
  • Excellent for fine control By Chris on 5/17/2016

    I use two of these. one to tune my Herbie overflow and the other to tune flow through my fuge. Very well built
  • Excellent fine-tuning but needs constant adjustment By Jazmyne on 5/31/2015

    I used the spears 1" gate valve to replace the ball valve I originally installed on the siphon to my sump. I've had it on my tank for nearly six weeks. While it's much easier to dial in than the ball valve, I find I have to adjust it every other day or so to keep the water in the overflow at the right level.
    For the price, I would expect it to hold its setting better.
  • High Quality Parts By Kyle on 5/1/2015

    I opted for the Slip X Slip version of this valve and was not disappointed. Welds very well (made sure to weld while valve was open - didn't want gunk on the gate itself) and you can just tell that it's built to last. Turning action of the valve is very smooth and you can fine tune with these extremely well. My ONLY wish is that they made a True Union version of these rather than me having to put unions on both sides.
  • High quality product By Michael on 1/7/2015

    Having gone to a few different hardware stores while deciding what to get for my plumbing, I went for this based one great reviews. The reviews were right, well worth spending the extra money to get a high quality product that will last longer and be easier to use long-term. Don't waste your time or money on ball valves!
  • You Need To Buy This By Evelio on 12/9/2014

    This valve helped me maintain a precise flow through my sump. I will definitely be purchasing more of these valves in the future.
  • Spears Gate Valve. By onecansay on 8/20/2014

    Spend your money once. This is one serious valve.

  • Adjustment is key By Tim on 2/6/2014

    These valves took my overflow from slurpy to silent!!

    minute adjustments have literally made my overflows silent.
  • Great Valve; Worth Every Penny By Brandon on 1/30/2014

    This is an extremely well made product and I would recommend this to everyone; even if you used sch 40 for everything else, get this. With this valve, you're able to adjust your water so precisely that it makes live so much easier.
  • very percice By jimbo on 1/29/2014

    Used them for supply and return going to refugium easy to dial in and very compact.
  • Great for fine tuning By Jack Murray on 7/2/2013

    A few months back I purchased one of these valves to mod my skimmer so I could skim most efficiently. I have been using it for around 4 months straight now on my skimmer and I could not be more happy the valve handle turns in a very smooth fashion it does not require you to hold your skimmer in place while turning the valve which is also great. The second you take it out of the box and handle it you understand why it is so pricey it is very sturdy and rugged feeling. I highly reccomend the spears gate valve. Also don't try going out and looking for this valve at your hardware store you are just wasting your time I learned that the hard way.
  • Great valve By Bill K on 5/20/2013

    Installed in my return line works great now i can control my water pressure.
    Well worth the money
