Valve Tech / Pipe Diameter Change

« on: May 07, 2023, 03:18:38 PM »

Hello -

I have 1" line coming off my submersible but 1-1/4" line on distribution lines.  During an initial piping setup, does the CSV care if I go directly into it with 1" (internal threads) and exit with 1-1/4" (using the external threads) or should I transition farther from the valve itself ?    If so, on the upstream or downstream side of the valve?

Thanks

Pumps, Wells, Tanks, Controls / Flooded Suction Jet Pump Setup

Cary -

Planning a setup with jet pump fed by a cistern approximately 5 feet above the pump level.    Will be using a CSV and an existing Amtrol tank with about 12ish gallons of draw down volume at 40/60.    Two story residence with all other water spigots downhill.   Looking at the Goulds J5S pump or would the J5SH (or higher HP pump) be more appropriate?  I am presuming that these types of pumps would be fine with flooded suction with appropriate check valve in place.     Any other pump brands or types for this kind of application?

Thanks

Pumps, Wells, Tanks, Controls / Automatic Submersible Pumps?

« on: May 07, 2021, 09:04:20 PM »

What are your thoughts on using a CSV with automatic submersible pumps installed in a cistern that turn on/off based on integral pressure & flow controls like the following:

Strom BSP - https://www.swisspacific.com/bottom-suction-pump

or

Grundfos SBA-3-45 - https://product-selection.grundfos.com/sa/products/sb-sba/sba?tab=documentation

The demand controls (flow, pressure) would be before the CSV so wasn't sure how that would effect things if at all.

Thanks

Thanks - couple follow on questions.

Is a Dole valve similar in function to a pressure sustain valve?    Will a Dole valve work as well? 

Any recommended vendors for 24V solenoid valve?

Thanks again!

Cary -

It's been a few years (like 5) since my initial questions but I was wondering if you might be able to help on some related questions to the situation as described previously.  Probably not in the realm of Cycle Stop Valves but you obviously have many years of experience in water supply systems.

Question - looking for ideas on how to control my well pump when filling the cistern up at the top of the property. 

I have a 12v/240v pump start relay that I am currently not using.  My original thought was to use a cistern float switch and running a 12v signal from the cistern all the way down the hill to the well pump to control on/off.   However, do wireless techniques exist these days to do similar pump control or is that not reliable enough.   

The other option I guess is to just use a mechanical float valve in the cistern that would shut off flow and the pump would eventually shut off after reaching shut-off pressure via a pressure switch at the well.

The other item I need to control is run time during cistern filling operations so that I don't dry run the well pump.   Any ideas on this?

Thanks

Reviews / Requirement for a straight pipe runs before/after CSV?

« on: July 01, 2016, 11:08:53 PM »

Getting ready to install a CSV1A and I was wondering if there is any requirement for straight piping before and/or after the valve before going into the pressure tank?   Can I just thread a 90 Elbow directly onto the CSV1A input side or should there be a length of straight piping to reduce turbulence and pressure variations?   Likewise for the exit side going into the pressure tank?

Thanks

OK - thanks.   That makes sense.

If I wanted higher pressure in the garage and make pressures similar in both buildings, could I set a Pside-Kick kit to 40/60 and the CSV to 50 PSI at the cistern and then have a pressure reducing valve at the downhill cabin?   Can a reducing valve even adjust for that small a delta-pressure (~20 psi)?

Thanks again

Pumps, Wells, Tanks, Controls / Low production well with 3 supply zones

OK - just getting started trying to plan for water distribution on a property and looking for advice.

The property in question is sloped with the well house basically near the center.   We will be building a liveable garage on the uphill side (15-20 vertical rise) and a cabin on the downhill side (10-15 vertical fall) from well.

The well is low production (3-3.5 gpm) and I was thinking of putting a cistern uphill from the garage for storage/supply.   I was thinking of feeding the cistern with a line constrained with a Dole valve and controlled with 24v level switch.   I would then have a supply line (low pressure - gravity feed) coming out of the cistern that would be Tee'd to a booster pump/CSV setup in the liveable garage.   Then continue the supply line down to the cabin and have a similar setup for the cabin.   

Couple questions - does that sound reasonable?   Can you supply booster pumps directly from a line or do you need some kind of storage volume?

Next complication  - I have some irrigation line in the ground near the well that I want to feed for irrigation and/or fire control spigots along the edge of the property.   Again, this buried supply line is near the well not either of the structures and their associated boost pumps.   Any ideas on valving, etc around the well do accommodate this irrigation/fire control line?   Cistern in the wrong location ?  Another boost pump or is there something else that can be done to simplify everything for all three zones (garage, cabin, irrigation) ?

Thanks -
