They may also prevent sand from depositing in your plumbing lines. Lakos is a leader in the sand filtration industry and PlumbingSupply.com is your source for Lakos products.

| How to Determine Sizing |
Each SandMaster model operates best within a specific flow range. Do not simply use your system pipe size. To determine your pump's actual flow rate:
If you have a valve between the pump and the pressure tank, open it fully and record the volume of water in one minute to determine gallons or liters per minute.
If you have no valve, follow these simple steps:
- Immediately after your pump shuts off, open faucet between pressure tank and house (make sure no other water is running), run water into a container and record the Volume (gallons or liters) of water it takes for pump to start up again. (You may have to refill container several times)
- Record length of Time (in minutes) pump runs before shutting off again.
- Divide Volume by Time to determine actual flow rate (gpm).
- Select your SandMaster model accordingly.
