Question about Plumbing

1 Answer

I replaced my pressure switch with one that has a emergency low pressure off switch.

The problem is for example, if watering the garden and flushing the water pressure drops below the emergency off pressure PSI. Then I have to manually turn to start to get the water back on. Can the emergency off PSI be adjusted to say 10 PSI? I really want the protection but this switch is useless if I can't lower the emergency off setting.

There are a lot of variables. Are you on a shallow well pump? It sounds like the well doesn't make much water. Check your well tank pressure. With 0 psi of water (drain the pressure) There should be 2 psi of air less than than the start up. If the pump is set to start at 30 psi, there should be 28 psi of air in the tank. It sounds to me like either the tank is shot, or the pump doesn't make much water. If you leave a faucet on while putting air in the tank and air comes out the faucet, then, the bladder is shot.

SOURCE: Need to lower 1750 psi to 300 psi on my portable power washer.

Don't starve the inlet to the pump. It will detroy it.
Buy a pressure regulating valve and plumb it in line per the instructions. Do not use a relief valve because you will have to have a return line or you will heat the water up on the inlet side of the pump depending on how the pressure washer is set up. It should already have a safety relief valve. You might look and also find a pressure regulator that is adjustable and all you problems will be solved.

SOURCE: Heater is new, installed at grade on above ground

Adjust the switch fully in the opposite direction. If you are at 1.5 you are at the light end of the adjustment range of that switch, which can be adjusted up to 5psi. Then let it back off until it works reliably. Rarely do you need to adjust a pressure switch on an above ground pool so it should end up about in the middle of the adjustment scale.

SOURCE: I have oil pressure until i stop , then it drops to below 10 psi

We have to know which engine...

generally, warm, idling engine, oil pressure should read down to 15 psi

Range, normal driving around 40 ~ 60 psi.

High rps will get upwards around 70 or so...
These are general; your readings are low for normal driving.

Oil pump gears are worn, you should replace oil pump .

Other experts .. comment, please...

SOURCE: with compressor running, low side pressure starts

Wow, it would seem like you have a leak there on the low side. You add and it goes goes back to equal on the low side again. The gauge could be off just a bit. Have you pulled a vacum test on the unit? Sounds like you should pull everything out, vacum and the weigh in the correct charge at this point assuming that you do not have a leak or can find and fix it.

SOURCE: Lots of water on basement floor at pressure tank.

sounds like the bladder tank at the well is ruptured this will cause pressure surge, and pump short cycling, and needs to be replaced asap.

2003 ford e250 flush heater core

I flushed my heater core by taking the heater hoses off the heater outlet and inlet and taking a garden hose and run water under low pressure for about a minute on both hoses going into the heater and mine cleared right up. Good hot air after that. I had to take some anti freeze out of the rad so I wouldn't loose fluid when I took the hoses off. This worked for my car.

No pressure on my husky power washer 1650

Basic Issues As an electric-powered washer, a circuit overload may cause your Husky 1600 to shut down or prevent it from starting. In this case, check your home's electrical service panel for a tripped breaker or a blown fuse -- the 1600 requires a dedicated circuit rated at a minimum of 15 amps. To prevent a blown fuse, avoid using other large devices on the same circuit as your washer. If you use an extension cord, it must be rated at 15 amps as well. Before moving on to more complex troubleshooting measures, check the gun safety trigger and release the lock if your 1600's trigger will not move. Water Woes Releasing air from the pump serves as a simple fix for low-pressure water output; remove the wand and allow the washer to run as you depress the gun's trigger until the water output normalizes. If your water output seems to lack detergent, ensure that the clear tube is securely connected to the detergent nozzle. Likewise, check the connected water supply and make sure the faucet is fully open and that there are no kinks in the hose to ensure optimal pressure. Using a shorter garden hose makes for stronger pressure, as well -- Husky recommends a hose with a maximum length of 50 feet for a city water supply. Clearing Clogs If your Husky 1600's pressure seems lacking or its water flow is obstructed, clean the nozzle by removing the wand from the gun, clearing the nozzle hole of obstructions with a stiff wire and flushing the nozzle with clean water. Similarly, clean the washer's inner water screen, located behind the garden hose connector, by removing the screen and flushing it with water. This also corrects low or irregular pressure and may remedy a unit that does not stop releasing water when the trigger is released. Model HD1600 features a chemical solution reservoir with a similar screen; clean this screen in the same fashion if you experience chemical intake issues. More to Consider If your power washer issues go beyond troubleshooting basics, contact Husky's customer service department at 800-381-0999. Husky recommends contacting customer service when your 1600 has problems with its pump, bypass valve, discharge valve or manifold assembly, for instance. Because this series of powerwashers was originally offered around 2001 through 2008, Husky's one-year limited warranty no longer covers the cost of replacement parts or repairs.

Monitor heater keeps shutting off why?

78 olds uses a push and pull water controle on the heater hose. Make sure that the cable is working the water valve on.the heater hose. If it is working the valve back and forth then its most likley your heater core stopped up.. take both heater hoses off at the motor. Take your garden hose and flush water threw heater core. USE LOW PRESSURE.. DO NOT TURN YOUR GARDEN HOSE.ON FULL BLAST.. IT COULD MAKE THE HEATER CORE TO START LEAKING IN SIDE YOUR CAR. With.low pressure run water in each.heater hose.till water coming out looks clean. If this dont get you heat. Then check.your thermastat it may be stuck open.

Hot water pressure very low in maax shower any suggestions to correct?

Assuming that the flow control is not defective, your water heater may be limed shut.
Heating water (especially 'hard' water) causes calcium to precipitate out and build up in the bottom of the tank which can cause poor recovery and if heavy enough, reduced flow.

Check yours and you should find a drain located near the bottom of it.
Attaching a garden hose to this and opening the provided valve will allow you to flush out the loose lime.
You should turn off the AC or gas supply before doing this to stop the heater from trying to reheat while you are emptying it.

Good luck-

How to back flush heater core 2007 grand prix

drain coolant system locate heater cores hoses going through firewall you need to buy the radiator flush kit at any auto parts stores. remove heater cores hoses from one end or buy extra long heater hoses same size as heater core hoses in vechicle at auto parts store use the flush kit when you flush through one of the heater core hoses let the other hose drain in a drain pan when you use home garden hose use low water pressure dont use garden hose to the max or you will rupture heater core. your best bet let radiator shop flush whole coolant system. because heater cores hoses are in a tight spot.make sure engine off if you just going to flush out heater core only .after flushing heater core good time to replace heater core hoses.if job too hard or complicated let radiator shop flush out radiator the engine block and heater core because if radiator stopped up or engine block stopped up the gunk and rust will reenter plug up heater core.if you tight on money you can flush out your own radiator.drain out radiator using large drain pan. remove top radiator hose and remove bottom radiator hoses connect to water pump.use garden hose with flush kit part with water pressure not too high put garden hose to top radiator hose run water until clear water run out bottom radiator hose in drain pan,the flush out engine block remove thermostat.if you had another spare thermostat housing with RTV SILICONE SEALANT THAT HAS SET UP INSTALL THERMOSTAT HOUSING BACK TO ENGINE WITHOUT THERMOSTAT FLUSH OUT THE ENGINE BLOCK, WHEN DONE INSTALL NEW THERMOSTAT THEN INSTALL ORIGINAL THERMOSTAT HOUSING WITH NEW ORING WHICH YOU BUY AT DEALERSHIP.IF ALL SOUND COMPLICATED LET RADIATOR SHOP FLUSH OUT COOLANT SYSTEM.

Heater is very poor

Has the vehicle been run with anti-freeze its whole life? If not, then flush heater matrix.

With vehicle in cold state, disconnect heater matrix feed and return pipes from within engin bay. Turn the vehicle's internal temperature setting to hot. If the vehicle is fitted with climate control, then do this with the ignition in the 'on' position.

Take a garden hose and with low pressure first, try flushing the matrix. If the water pressure is not enough to flow through matrix at low to medium pressure, then a blockage is almost a certainty. If water does not flow at first, then try using a high pressure air-line to force air and any blockage material through the matrix and out of the exit pipe. You can also reverse the flow to blow or flush any dirt out of the other end.

Once all is clean and free flowing, reconnect and fill entire system with a 50-50 anti freeze-water solution.

If blockage cannot be resolved, then replace heater matrix.

If no blockage is present then continue to check heater control switches and wires.

Rust in water heater tank

the tank needs flushed out ! heres how. Water heater manufacturers recommend flushing sediment from your storage type water heater periodically.
If your water heater is gas, set the gas valve to "Pilot" to prevent the burners from coming on while you are flushing it. If your heater is electric be sure to turn off the circuit breakers. With an electric water heater, if the water level drops below the heating elements and the thermostat turns the elements on, the heating elements will probably burn out quite rapidly. Connect a garden hose to the drain valve at the bottom of the tank, Close the shut off valve on the cold inlet to the water heater. open the temperature/pressure relief valve at the top of the tank by lifting the lever. Leave the valve open. Open the drain valve at the bottom of the heater allowing the water to flow out through the garden hose. when the water is clear your finished. close pressure relief valve on top of tank and turn water back on.
Open a hot water faucet in your house, and let it run until no air bubbles come out.

Turn the heater back on, and with gas units re-light the pilot light if necessary. good-day !

Have a 2000 chevy cavalier. new water pump, new t-stat, new head gasket , new coolant, still running hot

Two ideas.

1. Try a new radiator reservoir cap (trust me, it is very important in holding pressure which keeps the coolant from boiling out).

2. This one you will need an entire weekend to spend on this. You need to remove the thermostat and replace the thermostat housing. pull one of the radiator hoses and attach a garden hose with good pressure. It needs to flush for at least 20 minutes. Then switch directions and flush water where was coming out. Then put it back together and drive until it gets hot. Allow it to cool for 45mins (to prevent engine from cracking due to rapid cooling) and repeat until no crud comes out when flushing.

Make sure the coolant level is full. If coolant levels are ok you made need to replace the thermostat .You can disconnect the heater hoses going to the heater core and flushing water through with a garden hose at low pressure. If the vehicle has the 4.3L engine these are quite prone to heater cores plugging up. Would try flushing the heater core first.If that does not work most likely the thermostat is causing your issue. Be sure to fill coolant back up after servicing and allow air to bleed from the cooling system.

There isnt coolant going through the heater core, therefore no heat. Is there a valve or could the core be blocked with something? It's a 99 Expedition Eddie Bauer.

yes very common you will have to flush it out using a garden hose with good water pressure. disconnect both hoses connect one to the hose and turn the water on keep switching to back flush it until clean water runs out of it. reconnect hoses and it will be fine.
