Sizing a waterer to your herd

Four numbers decide the model: peak head count, class of stock, whether the ration is wet or dry, and how hot it gets in July.

Step 1 — Count peak head, not average

Size to the highest number that pen will ever hold, including the week you are shuffling groups. A unit that is right for 180 head and wrong for 220 is wrong.

Step 2 — Convert to daily demand

Multiply peak head by hot‑weather intake for the class of stock. A 200‑head pen of 800 lb steers at 18 gal/day is 3,600 gallons a day and it will not be drawn evenly.

Step 3 — Check drinking spaces, not just volume

Reservoir volume tells you what the unit holds; drinking spaces tell you how many animals can drink at once. Peak draw after the feed truck, after milking is a spaces problem, not a volume problem.

Step 4 — Confirm supply and recovery

The waterer can only deliver what the line brings it. Confirm static pressure and flow at the riser, and match the valve accordingly.

Installation & frost depth

Most “the waterer froze” calls are not the waterer. They are the riser, the backfill, or the pad. Get these right and an energy‑free unit will run unattended all winter.

Supply below frost line

Bring the service line up inside an insulated riser tube from below your local frost depth. The riser is the heat path do not choke it or fill it with wet material.

Level, drained pad

Pour a pad that sheds water away from the unit on all sides. Standing mud at the drinking face causes more refusals than cold water does.

Square, anchored mounting

Anchor to the pad so the shell cannot rock. A unit that moves under a leaning cow will eventually leak at the riser seal.

Electrical, where used

Heated units need a dedicated, correctly grounded circuit with GFCI protection, installed by a licensed electrician to local code.

Stocking density matters

Energy‑free performance depends on traffic. An oversized unit on twelve head in a Dakota January is working against itself size down or add supplemental heat.

Protect from equipment

Fit guard rails where loaders, feed wagons and gates operate. The shell is tough; a bucket corner is tougher.

Always follow the installation instruction sheet supplied with your specific model, and comply with local plumbing and electrical codes.

Seasonal maintenance

Ten minutes a month is the whole programme. These are the checks our service desk asks about first when a call comes in.

Weekly

  • Confirm water level and that the float shuts off cleanly.
  • Check drinking balls move freely and seat fully.
  • Look for feed, chaff or manure build‑up at the drinking face.

Monthly

  • Drain, scrub and refill; inspect the basin for algae or scale.
  • Inspect the riser seal and pad for movement or washout.
  • Check guard rails and anchor bolts.

Before winter

  • Replace worn balls, seals and lids a poor seal is a freeze‑up waiting to happen.
  • Test heaters, thermostats and cord sets on heated units; verify GFCI operation.
  • Clear and inspect the riser tube; confirm insulation is dry and in place.
  • Confirm stocking density is high enough for energy‑free operation at your latitude.

Parts, warranty & claims

Ahrens products carry a five‑year limited warranty on the moulded shell against defects in materials and workmanship under normal agricultural use. Wear items, heaters and consumables are covered under their own terms.

Ordering parts

Order through your stocking dealer with the model number and the part reference from the exploded diagram. Common wear items typically dispatch from Grinnell within 48 hours.

Making a claim

Claims are handled through the selling dealer. Have your model number, date of purchase, installation details and photographs of the fault ready.

What is not covered

Freight damage, improper installation, freeze damage from an inadequate riser or supply, equipment strikes, and modification outside factory specification.

FAQ

Questions we answer every week.

Yes, provided three conditions hold: the supply riser reaches below your local frost line and is insulated, the lid and ball seals are intact, and the pen carries enough traffic to exchange water regularly. Where stocking density is low, exposure is severe, or the site is heavily shaded, we specify a supplemental heat package instead.

Published capacities assume moderate conditions and ad‑lib access. In hot weather, on dry rations, or with long walking distances, plan on the lower end of the range or add a second unit. Drinking spaces matter as much as reservoir volume when the whole pen wants to drink at the same time.

Algae needs light, warmth and nutrients. Covered drinking spaces remove most of the light; monthly draining and scrubbing removes the rest. Sloped, seam‑free basins with a proper drain plug make that a ten‑minute job rather than an afternoon.

Often, yes. The riser location and pad condition determine it. Send photographs and pad dimensions to your dealer retrofits onto sound pads are routine, but a cracked pad or an off‑centre riser is worth correcting while the old unit is out.

Almost always within a day or two. Introduce a group with a few animals that already know the unit, prop a ball open for the first day if needed, and make sure it is the only water source in the pen. Cattle teach each other faster than people do.

We sell through stocking dealers, farm supply distributors and co‑operatives. That network carries parts, knows local frost depths and can service what it sells which matters far more in February than a slightly shorter order chain.

Wear parts remain available well beyond a model’s production life. Give our service desk the model number cast into the unit and we will identify the current equivalent part.

Yes. We supply Canada and selected export territories through distribution partners, with export packaging and documentation handled from Grinnell.
