So I just realized after I glued everything together that I didn't put a valve on the sprout where vinyl tubing goes. I'm thinking the best solution may be to cut a few inches of hose and attach a valve to the hose directly. Will this work? Can I use the same PVC primer and glue to connect tubing to the PVC union valve? Attached are pictures. Thanks!

What is the tubing for? could you just put a valve on the end of it? if you want to put a valve next to the barb fitting (sprout) just get a valve with female threads and barb-to-male thread fittings to attach to the valve. cut a short piece of tubing to connect the barb fittings leading to the valve and put the rest of the hose on the other side. No pvc glue required, just hose clamps. I would recommend a 90 between the barb and the valve so you can brace the valve either vertically or horizontally.

The tubing is to fill up the tank which is approx 50ft away in the house. If I put a valve on the end, water will fill 50ft of tubing everytime I turn the pump on. I'm having a hard time visualizing what you explained. Could you dumb it down for me or possibly show pictures. Sorry I'm very inexperienced at this.

Maybe on of these would be best?

I think what dbowman5 is suggesting is to use a short piece of the tubing to connect a valve with a barb fitting to your current barb fitting. Couple of hose clamps on about a 4" or so piece of hose should solve your issue.

Looking at your linked valve, I'd prefer to go with something more robust, such as what you've already used.

Your other option is to read on the web about removing glued fittings and re-install what you wanted to do.
It involves cutting the current barbed fitting flush, grinding out the Tee remnants, then a lot of cement to melt out the old leftover part while not removing any of the Tee.

Thank you I really appreciate the help. You guys definitely gave me some food for thought. I'm going to try that barb valve I posted. If it's not strong enough to hold the pressure I'll buy a fitting saver and try to drill out the barb from the T fitting.

that would certainly work

i would use this type of valve (uness you want to use a full union valve which would be better) if you wanted to, use the elbow fitting first after the nipple you have, this would allow the valve to be positioned sideways rather than straight out from the tanks. when you operate the valve it will put torque on the hose fittings. if the valve was stabilized with clamps only the stem would move. i would still think about something on the end of the hose so it will stay in the tank when you turn on the hose fifty feet away, thus my suggestion of a valve on the end.
