Video Transcript for Valterra RV Fresh Water - Valves - P23401LF Review

Today we're going to be taking a look at the Valterra Brass Diverter Check Valve. This unit can be used for many applications, but most commonly used as a replacement for bypass kits when it comes to winterizing your RV water system. This unit's made from a durable brass construction. It's going to feature a lead free design. Also features a fresh water backflow preventer. Just to go over the different connection points real quick, on this end you're going to have the 1/2 inch FPT or female pipe thread connection, and then the other two are 1/2 inch MPTs, which is male pipe thread connections. The lever is the diverter, so that diverts the flow from this connection to this connection.

The FPT connection comes with the appropriate seal on there, as you can see, to ensure leak-proof performance. That's going to do it for today's look at the Valterra Brass Diverter Check Valve.

Valterra Check Valve - 1/2" - MPT x MPT x FPT - Brass - P23401LF

Average Customer Rating:  4.8 out of 5 stars   (4 Customer Reviews)

- P23401LF

Did the trick by shortening the distance to the pump and filter rather than using an adapter in between. Well made but a little expensive. 909100

  • 2018 Highland Ridge RV With City Water Filling Fresh Water Tank
    A backflow preventer like the Camco RV Fresh Water System Backflow Preventer - 1/2" Diameter - Brass # CAM23303. will allow water to flow only in one direction so that your fresh water tank doesn't fill up from water backfilling into it from your city water connection. If your connection requires a double male pipe thread connector then # P23415LFVP will be a good option. Included is a video overview with additional information.

  • Does Valterra Diverter and Check Valve # P23401LF Allow Back Flow
    Is there a check valve or any other type of diverter installed between the camper and the water supply? There has to be something that's preventing the water pressure from getting to your camper. For example the # P23401LF has a back flow preventer in it which only allows water to come out of the female fittings. If you have something like this installed you might check to make sure it's working properly.

  • Can Valterra Check Valve # P23401LF be Used as a Fresh Water Diverter
    Valterra Check Valve # P23401LF can be used to divert water from two sources so it can direct the water to go where you want it to. It does have built-in backflow prevention to stop water from traveling back up past the valve so you would not need another fitting for that.

  • Connecting to City Water On RV That Has Water Pump
    When connecting to city water that is pressurized you do need to bypass the water pump like part # P25201 that you referenced. To do that you can use a diverter like part # P23401LF. This would install after the water pump and as long as you switch it to the correct position it will allow you to have city water pressure without it backflowing to the water pump outlet.

  • Can the Camco Replacement 3-Way Valve for Winterization Bypass Kits Be Used for Drinking Water
    The Camco Replacement 3-Way Valve for Winterization Bypass Kits part # CAM37463 does contain very trace amount of lead but so do a lot of brass fittings. However, it is not rated for drinking water as stated by the manufacturer. The Valterra Check Valve part # P23401LF is lead-free so it would be rated for use with drinking water.
