Chemical Feeders
PoolSupplyWorld carries a great variety of chemical feeders for any preference and budget. We carry floating, in-line, and off-line feeders for in-ground and above-ground pools from the best names in the business, including Hayward, Polaris, Pentair, and King Technology. If you have any questions about which chemical feeder is right for you, please call us at (800) 772-0467.
A floating chemical feeder is a completely enclosed system and is the easiest type of feeder to use. Simply fill with bromine tablets or slow dissolving chlorine tablets, place in the spa or swimming pool and the chemicals are automatically dispensed into the water. Floating feeders are compatible with in-ground and above-ground pools and spas.
Advantages:
- Economical
- Simple design for easy use
- No wires or plumbing involved
In-Line Chemical Feeders:
An in-line chemical feeder is incorporated into your pool’s existing plumbing. Water is passed directly through the feeder via the plumbing system’s existing PVC pipe where it is chemically treated before being returned to the pool. In-line feeders are compatible with both in-ground and above-ground pools.
Advantages:
- Bulk feeders reduce work for the pool or spa owner
- Reduces manual handling of chemicals
Off-Line Chemical Feeders:
Off-line pool chemical feeders are ideal for the following situations: there is an existing pool or spa; there is insufficient space on the equipment pad for an in-line chemical feeder; permanent installation into the return line would be impractical. Off-line feeders dispense chemicals into the pool’s water through two small hoses that connect the feeder to the pool’s plumbing existing PVC pipe.
Advantages:
- Generally more economical than in-line chemical feeders
- Bulk feeders reduce work for the pool or spa owner
- Reduces manual handling of chemicals
Helpful Hints:
- Do not plumb in-line feeders into copper pipes; chemical corrosion will occur
- Adding chemicals other than those the manufacturer recommends can result in fire or explosion
- Chemical feeders should always be installed downstream of the pool heater. They should be the last major component before water is returned to the pool
- Throughout this section, you may see references to ORP. Everyone is familiar with pH, but ORP is a slightly less common term. It stands for Oxidation Reduction Potential and it is a measure of oxidizing capacity in water. ORP indicates water’s bacterial quality better than any other method. For this reason, ORP testing is usually legally mandated in commercial pools
