New Yard Hydrant

[CobyRupert]

Is there a check valve in the line coming from the well going in to the pressure tank ? If there is, then the check valve would need moved from the pressure tank and put in the line before the splice where your going to tee in for the hydrant.

^This.
Check valve may be just before ballast tank. Water would only come out hydrant directly from pump when pump is running, otherwise you get no water. Turning on hydrant wouldn’t automatically start pump because the check valve prevents pressure dropping in the ballast tank pressure and at the pressure switch.

I agree with the idea that you can connect to the line from the well however I wouldn't do it. For 30 yards of extra digging you can run a totally separate line. If you ever have any problems with the hydrant all you need to do is shut off the isolation valve in the house. You don't need to shut down the whole pressure system to fix any problems with the hydrant.

Yes, it’s fine to connect at the well end. I was fortunate to find an unused end of a T fitting to tap my shop line to. It was 3 ft deep. The thicker black pvc pipe on the left was notched at the bottom and fitted over a street valve. The top end of the pipe was glued to a female fitting with a screwed cap. The bottom & sides at the base is all gravel. This setup allows me to unscrew the cap and lower the shutoff tool should I need to cut off the shop line.

One more consideration to installing a freeze proof hydrant.
If you have heavy soil that doesn’t perk well be sure to provide plenty of opportunity for the back wash to drain away when the hydrant is opened and closed in freezing weather. I usually drop a 10’ long piece of perforated drain tile capped on the outboard end and covered with a foot or so of pea stone as a sump to absorb the water running back down the stand pipe when the valve is closed.
For the what’s it’s department, the Michigan plumbing code requires anti syphon valves to prevent cross contamination on all exterior hose connections which of course negates the purpose of a freeze proof hydrant.
To stay mostly compliant, I have a handful of those anti siphon dohickeys that go on the hose Bibb in the spring and come off in the fall.
I just love being protected from my self.......

My well is about 80 yards from the hose and 50 yards from the hydrant in the yard,
the check valve is on the top of the pump drop from the pitless adapter.
The piping 1 1/4" leaves the well runs about 30 ft and has a Y in it which is the split
for the house and hydrant. The pressure switch is at the house on the tank.
One issue is that my pressure switch is the type that drops out and shuts the pump
off on low pressure (15 psi) if the hydrant is turned on rapidly the system pressure
(40-60 psi) can drop below the 15 psi before the flow from the pump reaches the hose
and maintains the pressure resulting in the low pressure safety shutting the pump down.
If the hydrant is opened slowly or if the hydrant is on and the flow controlled by a spray nozzle,
no problem but that 1" hydrant wide open quickly will shut it down which means a trip to the basement
and lifting the shutoff lever on the pump to the run position and holding it for 5-10 seconds.
I have contemplated removing the low pressure safety switch as it has as of yet never functioned
in an as needed situation (broken line, low pressure, pump running continuously) just as an aggravation
during power outages and hydrant use.

Not a plumbing/well expert but...cutting into the line after it leaves the well but before the house means that unless the pump is running with yard hydrant open, the water is feeding back from your pressure tank through the filter and conditioner. I don't know if that is a bad, good or mox nix thing.

That is exactly how mine has been working for the past 40 years.
The yard hydrant did rust out after 30 years, so I shut the valves off at the tank and the pump, while I replaced the hydrant.
I do not have any filter or conditioner.

Who said backflow preventer?
I grew up drinking from the hose, riding in cars that did not have any seat belts, and riding my bike without a helmet.
I never did smoke though!

Mine too. House built in 1978 although I've only owned it 8 years. The line from the well Teed off to the hydrant in the barn before the internal house plumbing. My pressure tank is before my filter. Got a lot of sand & sediment out of the tank a couple years ago when I drained & flushed it. I've thought about re-plumbing it for the filter before the tank, but have seen some recomendations to leave it plumbed tank before the filter. So I haven't messed with it. I have added a few more frost free hydrants between the well & house though.

I like this style yard hydrant best: Baker Water Systems - Magnum Frost-Proof Hydrant
