    Residential Fire Sprinkler System / Private Well Water

    I told the customer there was nothing else I could do after the county shot down the bypass valve plan. She got them to agree to re-plumbing their system (we'll see what they actually do). The pressure system plumbing design follows my age old basic system design, but adds a tee to branch...

    Residential Fire Sprinkler System / Private Well Water

    We finished our part of the job today. We stubbed up a 1 1/2 inch unconditioned water pipe in the vicinity of the conditioned house water connection. The fire sprinkler contractor is supposed to tear out sheet rock, separate the lines and connect the fire sprinklers to our stub up, tomorrow on...

    Residential Fire Sprinkler System / Private Well Water

    Perhaps a 1 1/2 cubic feet with a 12 inch diameter vessel and 5810 Fleck valve. The cross section of the greensand to meet the flow requirements of the fire sprinkler is 8 square feet. A 42 inch diameter tank is 9 square feet and as you said, we can't backwash it. We would have to use multiple...

    Residential Fire Sprinkler System / Private Well Water

    The codes are published by the National Fire Protection Agency (NFPA). Everything should be standardized throughout the country. However it seems codes are subject to interpretation by jurisdiction and even by individual inspector. Here, in rural Merced County, the 10,000 gallon tank is required...

    Residential Fire Sprinkler System / Private Well Water

    I agree, with any system, the simpler the better. The sprinkler line is purged by the toilets. The well has high manganese at 1 mg/l. If and when we connect it to the unconditioned water ony, the toilet bowls are going to turn dark brown without constant attention. I think the whole system is...

    Residential Fire Sprinkler System / Private Well Water

    I'm with you. I've been arguing with them since I first learned how the system was set up. I've scolded them both to the point that they don't even want to talk to me anymore. I told my customer to ask what they would charge to separate the lines and they are unresponsive. The general told her...

    Residential Fire Sprinkler System / Private Well Water

    Here's the county's response. "Mike, Unfortunately I have 2 problems with your system. First the solenoid valve is not part of an approved Fire sprinkler system as per NFPA 13, Secondly who would be liable if the solenoid system failed?" The inspector has the link to this forum. Attached is...

    Residential Fire Sprinkler System / Private Well Water

    I agree on the paddle flow switches. It seems like they're often stuck in the on or off position. I have one that works like a engine's mass air flow sensor, but the timers and relays to make it function are complicated. I have a message into one of my irrigation suppliers about the sprinkler...

    Residential Fire Sprinkler System / Private Well Water

    I want to use 24 VAC because I want to install the solenoid valve below grade remote from the well. If the valve box were to fill with water I don't want 120 VAC present. The load center is going to be outside (if a well house is built) on a post. I figure I can install a red panel light on the...

    Residential Fire Sprinkler System / Private Well Water

    Nice catch on the pressure switch operation. I'll have to consider that. The paddle switch isn't going to work because I can't get to the fire line (it's in the wall).

    Residential Fire Sprinkler System / Private Well Water

    I appreciate everyone's input. I've had requests in at Flomatic and Cla-Val, but haven't heard back from either. The house is almost completed and I don't want to be the final holdup. BIMR suggests and Valvecrazy concurs the pressure switch controlled solenoid valve is the correct course (it was...

    Residential Fire Sprinkler System / Private Well Water

    That was the first thing I looked at. The pump is fine, we could even go down to a 1 1/2 HP unit perhaps. The size (to limit friction loss through the filter bed & valve) and cost of the conditioning equipment is impractical. Oh, the booster system. If there's not enough flow through the filer...

    Residential Fire Sprinkler System / Private Well Water

    I don't think the file is uploading properly. With the pressure reducing valve at the house the two lines are connected there, via the valve. First there's the raw water then the valve arrow pointing towards the finished water, then the check valve, again arrow in same direction. I want to place...

    Residential Fire Sprinkler System / Private Well Water

    Good Morning, BIMR, I appreciate your help. Actually the Asco valve and an FSG-2 switch were my first thought. If there is a standard way of accomplishing this, that is what I want to do (especially since it is for fire protection). If I use the solenoid valve I would probably put it near the...

    Residential Fire Sprinkler System / Private Well Water

    Thanks Valvecrazy, You were the one I was thinking of when I joined this forum to ask the advice. If you think that is the best approach then I guess I should starting figuring in that direction.

    Residential Fire Sprinkler System / Private Well Water

    Hello, I'm the well drilling, pump and water conditioning contractor for an under construction private residence. The water is going to require an iron removal system and softener. The fire sprinkler system connection is already installed in the interior of the house walls and is fed off the...
