Hi and welcome to FixYa, I am Kelly, If this is a new unit there is very little that you can do to in and NOT void the warranty. You can disconnect the main pressure line from the pump to the tank and then hold your thumb over the hole to check and see if the pump is actually building pressure. If that works then you need to check the air hose connection and the air control ON / OFF selector to make sure it is in the OFF position. Other than that you have a product warranty issue.
The unit has a minimum of 1 year warranty (longer on many models)

How do I take apart a dewalt d5141 compr3ssor?

This number is for the D20114 its the safety valve that can not be set to a max basic pressure .
its strange but its not adjustable it can be defect i have one time the same the experience there is not a adjustable Pressure Switch on this model , the moast compressors have a 8 to12 bar adjustable.pressure switch.
Very important This safety valve gives an electronic brake between the pump and to a end of top about 10 bar . if its not switching off then a drain valve opened . and blows all the air out. (but only over 10 bar ) the max pressure on the tank , the moast tools are working on a pressure from 6 to 8 bar.

Checking Safety Valve
WARNING: Risk of bursting. If the safety valve does not work
properly, over-pressurization may occur, causing air tank rupture or
an explosion.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. If the valve is
stuck or does not operate smoothly, it must be replaced with the
same type of valve.
Draining Air Tank (Fig. 1)
WARNING: Risk of unsafe operation. Risk from noise. Air tanks
contain high pressure air. Keep face and other body parts away from
outlet of drain. Use safety glasses when draining as debris can be
kicked up into face. Use ANSI S12.6 (S3.19) ear protection as air flow
noise is loud when draining.
NOTE: All compressed air systems generate condensate that
accumulates in any drain point (e.g., tanks, filter, aftercoolers,
dryers). This condensate contains lubricating oil and/or substances
which may be regulated and must be disposed of in accordance with
local, state, and federal laws and regulations.
1. Ensure On/Off switch (A) is in the OFF position.
2. Move compressor into an inclined position so drain valve (H) is
at the lowest point (this will assist in removing moisture, dirt, etc.
from air tanks)
3. Place a suitable container under the drain valve to catch
4. Grasp black lever on drain valve.
5. Slowly rotate lever to gradually bleed air from air tank.
6. When air tank pressure gauge reads 10 PSI (275.1 kPa), rotate
valve to the fully open position.
7. Close drain valve when finished

Hot water valve leaking how do I take part no.

You will need to turn off the water heater first. Shut off cold water inlet valve to tank. Open the drain at bottom with hose attached to suitable drainage area, hot water will damage plants and grass so if you want to use the water let unit cool off for a few hours or drain down past the valve level. You can open the release on the temp/pressure vale and it will help vent and allow you to know the level. Take a small pipe wrench or large channel lock pliers and remove the drain line pipe connected to the valve body. Open a faucet that is the longest run and wait. The valve can be found at most home centers and are basically all the same with the BTU and pressure rating on the label. Take with you to match length and ratings. Apply Teflon tape or pipe dope on threads to help seal the fitting and tighten up till unit is secure and the opening points down for overflow pipe installation, reseal and tighten. Close off drain and refill with faucet and valve release open, when water starts to run out of valve close and continue filling until all air is bled out. Then relight water heater or turn on power. Check for leaks and test valve for operation. The TP valve should be tested annually for safety.

Husky air compressor

Your compressor shouldn't run more than ten to fifteen minutes before shutting off. The pressure should be posted on the machine somewhere ( a decal usually says xxxpsi). You evidently have an air leak somewhere. On the bottom of the air tank there is a valve for draining the tank of air and any moisture. Make sure to close that valve by hand only (Screw it in all the way by hand and remember, you are working upside down, so don't get confused as to which way to turn it). If the valve will not unscrew to drain the tank, you can use a pliers to loosen the valve to let the air out, but be sure you are turning it in the correct direction or you'll break the drain valve!! Now that you have the drain valve closed, turn the compressor on and watch the pressure gauge. When the pressure gauge reads the pressure on the decal, the machine should turn off. If the pressure gauge stops climbing before it reaches the specified pressure, you have an air leak somewhere. You can either feel for the leak at the air line connectors by hand or mix a dish soap and water solution the pour on the air line connectors to look for the leak. Keep the soap solution away from the motor!! When you find the leak, drain the tank using the drain valve at the bottom of the tank, disconnect the hose coupling that is leaking and wrap Teflon tape around the threaded portion of the male end of the fitting (3 wraps should do it) and reconnect the coupling ( tighten it well). Close the drain valve and start the compressor again. and check all fittings for leaks again.

Turn on frecuntly

If it is restarting that frequently you have an air leak somewhere. First check the drain valve on the bottom of the tank. If that's closed do the following to find the leak: You should remove the cover on the manifold where the guages are and get a spray bottle with soapy water in it. Let the compressor run until it shuts off then unplug it so it won't keep restarting while your working. Spray the soapy water on things like the copper line from the pump to the tank, the pressure regulator, guages and around the tank drain valve. You are looking for bubbling from an air leak. Make sure it's from a leak and not just boiling the solution off as parts of the compressor will get quite hot while it's filling the tank. Whatever is leaking has to be tightened or replaced.

Leak (drips) from the plastic knob/valve at the bottom from of the water heater. Model: Ruud M50-2 (installed in 1996)

This is your water tank drain or boiler ****. If it's plastic, it cannot be repaired so replacement is necessary. Of course you will need to drain the tank* first before replacing the valve.

* First turn off the circuit breaker for the water heater. Turn off the cold water supply to the tank. Open all of the hot water valves at each faucet in the house for proper drainage. Connect a garden hose to the tank drain with the other end emptying into into your basement drain or to outside of the house. Open the tank drain valve slowly and allow it to drain completely.

Once it has drained, use a pair of channel-lock pliers (aka water pump pliers or arc joint pliers) to turn the base of the valve counter-clockwise and remove it. Take this valve to a plumbing, hardware of home improvement store and ask for a replacement. I recommend a brass replacement valve but a PVC one is acceptable. Pick up a roll of 1/2" teflon pipe tape too.

Wrap the pipe thread on the new valve with 2 or 3 wraps of the teflon tape. Start the valve into the drain hole by hand, then tighten with the pliers until snug and valve oulet pointing down. Make sure the valve is closed. Turn on the cold water supply valves then turn off the faucets in the house once they are purged of air. Allow the tank to pressurize and check for leaks. If good, turn on the circuit breaker and you are good to go.

I have had this problem intermittently - often it occurs if I left the compressor pressurized overnight (i.e. forgot to drain it.) In the morning the pressure has gone down - I can turn it back on and...

There is only one relief valve and it is on the outside. The valve is set to open if pressure builds past 160psi. You may be having trouble with the pressure regulator (large knob with high/low arrow). This regulator will leak at times. You can determing if it is leaking by unplugging /shutting off the compressor when you hear the leak. If the leak stops as you shut it off then most likely due to discharge tube seal at the head of the pump. If you continue to hear leak after shut off turn pressure knob counter clockwise all the way out. If you hear a change in the amount of leak or stops then pressure valve is problem.

Check the oil in the cylinder, check if single phase type on the capacitor to the motor, replace if the speed/torque is low.
check belt for slippage ,if so tighten by pulling the motor backwards after loosening the mountings and then tightnening.
If the motor speed is good and still the pressure build up is low then it is possible that there is low compression in the cylinder. Might have to overhaul to better efficiency. Hope there is no leak in the tank or drain or the cut off valves.

The pressure will not build up

Remove the air from the compressor using the drain valve.
Remove the discharge hose. The one that goes from the pump to the tank.
Remove the air filter (and check condition)
switch the compressor on an with your hand, partially cover the air intake where the air filter bolts on(be carfull not to fully cover it).
You should feel the pump drawing air in.
If it dosn't draw you have a broken/leaking valve or a blown cross-over gasket if it is of the type with a split valve plate.
You'd need to remove the head/valves/plate to confirm this.

If it did draw in air,
Stop the compressor & re-fit the discharge hose.
Now run for a few seconds and check the draw again.
If its suction reduces you also have a valve/plate/cross-over gasket problem.

If it draws fine.

stop the compressor and loosen the discharge hose at the tank end.
You may hear a short air leak at first, but you should not hear air contniously leaking.
If it continiously leaks air then the check valve in the tank is shot.
NOTE: NEVER remove this valve if the compressor has air in the tank/receiver.
This should locate your problem for you.
