Keep in mind that the Humat 4-way Hydrant Valve is the simplest-to-use and maintain appliance available today. These operating hints PDF and maintenance procedures PDF are to help those of you who must write your department’s technical directives. First engine drops pre-connected valve at the hydrant and stretches line to the fire. Valve is connected to the hydrant, smaller chamber is positioned up or down depending on location of fire and hydrant is opened. Second engine lays two lines from fire to hydrant, connects sleeve to valve to supply those lines through the pump. Line is connected from pump discharge valve to bring initial supply line up to pump pressure. Please click the link below to access the contact us page. One 20′ section of 5″ Snap-Tite hose with 5″ Storz couplings was attached to the small chamber and to the pump inlet. The hydrant was on 20″ main with static pressure of PSI. Un-boosted readings in hydrant mode were the only readings taken because the friction loss and turbulence went to a negligible level when switched to pump mode, even with GPM flows.

Hydraulic Valve Hookup Questions

Connect sewer hose to RV park sewer connection with a dip in the hose providing a sewer vapor block. See the illustrations above. Open both the black and gray water discharge valves. When putting solids into the toilet, flush and then fill the toilet bowl twice 2 times to the top with water and flush. The force of these 2 flushes will push all the solids out of the black water tank into the parks sewer line, stopping any vapors going up the tank vent.

Re: Water Heater Gas Hookup Connections; Author: mr leak (CA) Use 1/2 inch black iron pipe like the dryer and run it to where it is to the water heater Then install a gas shut off valve and then hook up the 24or 18 inch corrigated gas flex to the water heater.

When I have water in my fresh water tank and I run the pump and faucets, I see water coming out my city water hook up connection. This did not happen last year. The most likely cause is a bad back-flow check valve. This check valve is there to prevent water that is held in your fresh water holding tank from back flowing out through your city water connection.

You can get one of these valves at most RV parts stores like Camping World or a hardware store. As a temporary fix you could buy a solid cap with garden hose threads that screws into the city water connection, or use the cover that should already be there to prevent the back flow until you can replace the check valve.


Inline Tube sells these pro-quality Rigid flaring and tube-bending tools to make the job much easier. Inline Tube can also supply prebent stainless or mild-steel tubing to fit almost any Chevy application. Adding a taller rear tire will upset the rear brake balance, because a taller tire increases the leverage the brakes have over the tire by increasing the distance between the axle centerline and the ground. Have you ever slammed on your hot rod’s brakes really hard? Did the rear brakes lock up before the front ones?

In most recreational vehicles you have some type of freshwater system, gray water and black water systems and holding tanks. While the term fresh water goes without explanation, gray water represents fresh water that has gone down the drain in the sinks and showers and into a holding tank.

Hydraulic systems use liquid under pressure to perform work. Designing and building a hydraulic system requires some mechanical knowledge and specialized components, but the results can allow a machine to do jobs it would be difficult to do otherwise. Steps 1 Understand how a hydraulic system works. There are basically four elements to the system, as well as possibly many smaller associated components for specialized purposes.

Here are the basic four and a brief description of each. This is a tank or other container that holds the fluid to supply the rest of the system. These are the pipes or hoses which transfer the fluid from one element of the system to another. This device pushes hydraulic fluid through the circuit and provides the energy for the system to do its job. Hydraulic motor or cylinder. This is the component that causes something to move, driven by the power of the hydraulic pump.

Subcomponents that manipulate or regulate the fluid as it does its job include various valves which allow excess fluid to bypass the hydraulic motor or cylinder, control valves or valve spools, regulators, accumulators, pressure switches, and pressure gauges. This can be an electric motor, and internal combustion engine, steam, wind, or water power. The main requirement is that the means for supplying the system with energy is that it is available and can generate sufficient torque for the purpose it is intended.

How to Wire a Zone Valve A zone valve helps control the heat from a thermostat for an area of your home, such as a bedroom or living room. A control box is wired to thermostats in your house and controls the zone valves. When a zone valve receives an electrical signal from its thermostat, it will open or close. Heated water from a boiler can pass through an open zone valve to heat the thermostat’s area. Try these steps to wire a zone valve.

Steps 1 Familiarize yourself with the instruction manual for your zoning system.

feet ( meters) of 1/4 inch OD copper tubing, a saddle type shutoff valve (nonpiercing), (2) 1/4 inch brass compression nuts, (2) ferrules/sleeves, and instructions for installing a water supply line.

I have been repairing appliances for 25 years, I run my own appliance repair business. Verified Hello Todd, Is this a single valve or double valve? My dilemna is not remembering what side of the valve the wires hook into. There are two whites which go into one ear of the valve and then a single brown wire which hooks to the other. Does it matter which plug in on the valve these wires go into. The plug-ins actually have markings If you do find ice in this tube either pull the tube out from the back and soak in warm water or if the tube will not come out defrost it with a hairdryer.

I have called the appliance center and they have told me I can come in and swap out the valve for a different one since I am beginning to think my “new” valve is a NO GO Unless you have something else in mind? I appreciate your patience thus far! If the fill tube is clear and there is no water going into the tray and you have replaced the valve it means the ice maker is bad. Even though you may see the arm moving the fill timer may not be engaging.

At either rate if the fill tube is clear it’s the valve or the ice maker. I suspect it’s the ice maker since it’s a very rare thing for a new fill valve to be bad.

The position of the one SCV valve that comes in base equipment for and Standard Tractors is in position 1, closest to the hydraulic block on the left-hand size. Positions of additional SCVs The more SCVs that are ordered or added change the position of the SCV valves.

Have I helped you? The symptoms are a “stumble” and what feels like an erratic loss of power when cruising around at partial throttle. EGR means “Exhaust Gas Recirculation”, the process of sucking exhaust gases back into the engine to re-burn them. It is a technique that reduces the pollutants emitted by the engine. There’s a vacuum line coming off the intake manifold to the EGR actuator.

The actuator is on the firewall and it’s an electric device controlled by the PCM that modulates how much vacuum pressure gets past it. From there, another hose goes to the EGR Valve. Vacuum pressure opens the EGR Valve, allowing exhaust gases to be pulled from the exhaust manifold, past the DPFE tubes, then back into the intake manifold. There’s a differential in the pressure, one tube has more pressure than the other one.

Trying to compensate, the PCM opens up the actuator too much. This excessive amount of EGR combined with the air coming in via the throttle body leans out the fuel mixture, causing a lean misfire, which is the “stumble” or “hesitation” that is common as the DPFE Sensor fails. The DPFE sensor in the Focus is not very robust, requiring frequent every 30k miles or sometimes less replacement or a work around. If you’re experencing stumble or hesitation while cruising, and think that it might be related to DPFE sensor failure, try one of the workarounds listed toward the end of this article.

If the stumble goes away, then your DPFE sensor is more than likely failing.

Your reciprocating piston compressor will have a smooth start up, thanks to the unloader valve. It blows off the pressure inside the discharge pipe when the compressor stops. There is another type of unloader valve , which can be found at the inlet of rotary screw compressors, also called inlet valve or loading valve. How does it work and why is it there? Air compressor unloader valve.

The output of the piston compressor is connected through a pipe to the air receiver.

How to Install Cement Board Around a Shower Valve Many bathroom remodel projects include opening the walls and repiping the water lines for a shower valve. Also known as mixing valves, single and dual-control shower valves install by connecting unions to threaded fittings on the hot and cold lines. Depending on the manufacturer and style of the valve, the connections may be on each side or at the underside of the valve.

A do-it-yourself homeowner with basic skills can hook up a new shower valve using everyday hand tools. Loosen and remove the unions from the hot and cold ports on the new shower valve, using an adjustable wrench. Screw each union into the port from which it was removed. Hold the valve stable with one hand and tighten each union with the wrench.
