The Bison Pumps come with a Lifetime Warranty on the stainless-steel parts and construction. However, you may still need to perform maintenance on your pump. Maintenance is rarely required beyond winterization, but some situations can cause excessive wear or damage to consumable pump components.
Cup Seals and O-Ring:
If used normally, these seals will last many years. The wear to these seals is directly related to the amount of pumping and the condition of the water. If your water has contaminants they could act as an abrasive and cause wear to the packing gland, piston cup seals and O-rings.
f you’re in a situation of high use AND low-quality water, the sealing components may need to be replaced eventually. For this, you can call and order the Bison Pumps Seal Maintenance Kit (https://www.bisonpumps.com/product/repair-kit/). The kit has everything you need to repair your pump.
Bison Tip: While you’re got your pump disconnected, take advantage of this time and clean the inside components of the pump. It’s best to first remove the components that will be replaced and THEN clean the inside of the pump. Finally, install the new components. While it’s out, inspect the Check Valve in the bottom of the Piston and Check Valve Housing. Make sure it’s clear of any debris that might prevent the Check Valve from closing properly. Given proper care, the Check Valve should last a lifetime. However, if the Check Valve is damaged by large debris, call Bison Pumps for a replacement. 1-800-339-2601.
.The owners of private household water wells in areas affected by hurricanes, and other flooding situations, should act to address possible threats to their drinking water quality , according to the National Ground Water Association.
If a well has been flooded:
Do not drink the water or wash with it, but use an alternative supply such as bottled water
Stay away from the well pump while it’s flooded to avoid electrical shock
Get a qualified water well contractor or pump installer to —
Clean and turn on the pump
Flush the well
Disinfect the well
Perform any other necessary maintenance
Check with the local emergency management agency about any guidance relating to local conditions or specific contamination threats due to area flooding.
Bacterial contamination is to be expected in a flooded well, so disinfection of the well system after it has been pumped out and cleaned will be necessary, said Cliff Treyens, NGWA director of general public outreach. NGWA recommends that water well system professionals be used to assess and service the well.
Well owners can search for NGWA-member or NGWA-certified professionals at WellOwner.org under “Finding a Contractor.”
Other resources for well owners in flood situations can be found in the “Water Quality ” section of WellOwner.org
Proper construction and maintenance of household water well systems is vitally important to public health. Water quality can be endangered by well systems that are deficient due to (1) neglected maintenance, or (2) because the well is beyond its useful lifespan.
Too often, urgently needed water well work is not done because either well owners cannot afford it—or they perceive that they cannot afford it. With this in mind, the National Ground Water Association (NGWA) has developed a new online video to help homeowners explore options for financing needed well construction or maintenance in ways that fit their needs.
Groundhogs sing us a song about Groundwater. Concepts cover the historical path of water, uses of water and dangers groundwater faces.
Well diggers learn manual drilling in Africa. This is one of the many different techniques trained by SMART Centre Jacana in Zambia.
It is time to set the record straight on some of the comments in blogs or from other hand pump websites. Here are some things being said:
“Bison cannot pressurize a tank.”
Nothing is further from the truth. All of Bison’s pumps can pressurize a tank. We factory tsted our pump and cylinder to 250 psi (for test purposes only). Every spout can accommodate a check valve to make this task easier. For the record, our pumps have always had this capability. As you can see by the pictures below, the picture on the left is the Bison One-Piece Shallow Well Hand Pump and the picture on the right is the Bison Deep Well Inline Hand Pump.
“Bison Pumps “pump harder” and cannot reach as deep as other pumps.”
It is simple physics… deep well hand pumps LIFT water. The deeper you go and the larger diameter the cylinder, the heavier the water will be.
The first was born out of necessity during Maine’s Great Ice Storm of 1998, which crippled parts of Maine for several weeks. Over half of our State lost power, some areas for more than 2 weeks.
Like many Mainers faced with adversity, Mr. Harbison and his team of plumbers responded to disaster with resilience and innovation.
They designed and built what would be the first Bison hand pump, which allowed people whose electric pumps were inoperable in the aftermath of the storm to access the water in their wells. Since 1998, this timely and resourceful design has gained international appeal and application.
