Frequently Asked Questions
Is 1402 adjustable?
No. 1402 has a fixed rated flow of 0.50 gpm; choose a different model if the design requires another output.
What connection does it use?
The inlet has a 1/2-inch female thread for a matching male riser.
What pressure does it need?
The operating range is 20–90 psi at the bubbler. Pressure compensation works within that range.
Why Buy from Big Frog Supply?
Choose 1402 when the planting plan calls for a 0.50 gpm trickle rather than the 1401's 0.25 gpm or the 1404's 1.00 gpm umbrella. Its fixed output and 1/2-inch female inlet make flow selection and riser fit the two checks to make before ordering.
