Q: HOW DO I SELECT THE PROPER FILTER SIZE? A: SELECT FILTER SIZE BASED ON FLOW RATE. 1 in. - 1-25 GPM 1-1/2 in. - 10-50 GPM 2 in. - 18-100 GPM THE SIZE OF THE PIPE USED IN YOUR SYSTEM MAY NOT BE THE BEST INDICATOR. NOTE: SPIN OUT SEPARATION IS BEST AT HIGHEST FLOW RATES. PRESSURE LOSS IS BEST AT LOWER FLOW RATES. Q: WHAT IS THE BEST UNIT FOR WELL WATER TO MY IRRIGATION SYSTEM AND INTO MY HOME? A: THE BEST CHOICE IS A 1-1/2 in. FILTER WITH 100 MESH. (CHECK THAT YOUR GPM DOES NOT EXCEED 50 GPM) PART # NT 1-SO 100 P Q: WHAT IF THERE ARE CHEMICALS IN THE WATER? A: OUR FILTERS ARE RECOMMENDED FOR USE WITH WATER ONLY. WE HAVE CHEMICAL COMPATIBILITY INFORMATION AVAILABLE. WE ALSO OFFER A HIGH PERFORMANCE CLEAR COVER THAT IS CHEMICALLY RESISTANT. Q: WHAT IS THE MAXIMUM OPERATING PRESSURE? A: DO NOT EXCEED 150 PSI AT 73? F ON ALL FILTERS . Q: WHAT IS THE MAXIMUM OPERATING TEMPERATURE? A: DO NOT EXCEED 100? F AT 40 PSI ON ALL FILTERS
Q: WHY DOES THE SCREEN IN MY FILTER PLUG SO FAST? A: THE MESH IS TOO FINE. CHANGE TO A COARSER MESH. Q: WHY DOES THE SCREEN STAY PLUGGED AFTER PURGING? A: TRY CHANGING TO A COARSER MESH OR THE SEDIMENT IS LIGHTER THAN WATER AND WILL NOT PURGE. Q: ALGAE GROWS INSIDE THE CLEAR COVER. WHAT CAN I DO? A: USE A COVER GUARD OR ALUMINUM FOIL AROUND THE COVER Q: WHY DOES THE FILTER LEAK BETWEEN BODY AND COVER? A: TIME TO REPLACE O-RINGS Q: WHAT CAN I USE TO CLEAN THE ELEMENT? A: HOLD UNDER RUNNING WATER. FINE SEDIMENT WEDGED IN THE SCREEN MAY BE REMOVED WITH A SOFT BRUSH. SOAK IN ? BLEACH AND ? WATER FOR STAINS.

I plan a VU-Flow VFNT 150 – 100 SSP 1.5 inch, 100 mesh stainless steel filter, downstream of the pump; a K-rain 4606 1.25*1 inch, 6 outlet, indexing valve downstream of the filter;
and K2 Pro sprinkler heads.
The unfiltered well water will gum up the built-in filter of the K2 Pro over a period of 2 to 4 months.
1.What is the procedure for back-flowing the filter to clean it?
2.Do I need a shut off valve upstream or downstream of the filter?
3.Is the replacement filter VFNT60SC100SS 1.5 inch, 100 mesh stainless steel?
4.Will this filter prevent gumming up the indexing valve and K2 Pro sprinkler heads?
5.My pump flow rate is below 10 GPM; consequently, I will require a stem and disk assembly with a lighter spring. Can I buy and indexing valve with this lighter spring installed?
Question 3: Yes, the VFNT60SC100SS filter is stainless steel. That's what 'SS' means at the end of the part number.
Question 4: with filter after the pump, it should prevent enough particulates from reaching your control valves and sprinkler heads to prevent clogging. Just keep an eye on that clear filter housing and flush it whenever it appears to be filling with silt. I would guess in a normal ditch water situation, you could run it for a season before it needed flushing. The valves and sprinklers can tolerate a certain amount of silt and still self clear and operate, but with shorter life. With this filter, that life will be extended greatly. If you were experiencing clogging of valves and sprinklers, I would bet that it was due to years of use under those conditions. This should help that situation greatly.
Question 5: can't answer. Not sure what you mean. It is the pressure, not the volume, that maintains the seals. It should work fine, even at low volume.
