The valve on the water tank in my Pinguino won't let enough water flow into the tank. It is a new valve, what can I do to adjust it to let more water into the tank?

I think that's hows it designed. 1.6 gallons per flush. Hold handle down for longer flush/more water flow.

allow tank to fill a little more by adjusting fill valve. When there's not enough water flowing from tank the stopper can over-power the water flow and cause the flush to stop by re-sealing.

Just to confirm that the pressure tank was pre-charged with the tank emptied of water. If water comes out of the air valve, then the bladder is ruptured, and the tank needs to be replaced.

Check for balance pipe between tanks that allows the equalising of air pressure between tanks as the fuel will not flow from tank if there is no air release. check for correct cap on second tank

The reason for toilets running is one of 2 problems. 1)The flush valve (or flapper) is not closing/sealing properly. 2)The fill valve is not closing properly.

Regarding the flush valve; usually it's the chain connecting the handle to the valve hanging up on something. When the valve is closed, the chain should have a little bit of slack in it. Sometimes these valves actually get cracks in them from age and that doesn't allow a good seal. So you could try a new flapper or whole new flush valve.

Regarding the fill valve; most of these have a floatation device. Make sure the float is able to rise all the way to shut off the valve. Watch the water come into the tank; there is an overflow tube in the middle of the tank. If the water goes into the over flow tube that means the float is not rising high enough to shut of the valve. Where I live there is a lot of lime in the water and this accumulates and can causes problems with float movement. Or it could be out of adjustment. The old floats had an arm you could bend to adjust and the newer ones twist up or down on the valve pedestal.

In closing, both valves are fairly cheap and anyone with some basic tools and a little know how can change them out. I hope this helps.

If ther is not enough gravity feed from the tank ( fuel tank low in the tractor ) it will not allow the fuel to flow on gradients, try raising the tank with spacers under the fixings of the tank

I believe 640 is typical tank-type atmospheric-vented gas water heater.
Gas water heater problems can get complicated. New heater sells for $350 at local box store.

If thermostat is not controlling temperature accurately, then (1) gas control needs replacement (2) water heater has sediment build-up (3) combustion and burner parts need cleaning. (4) All three things above, plus additional causes such as bad venting or not enough combustion air.

Usually recommended that plumber replace gas control valve thermostat:

Hi keithn60...

I had the same problem one time with my toilet tank, the answer is to put some silicone on the seal washer between the take and bowl assembly and to use a level on the tank to tighten it just enough to be level and not leak.
Please take time to rate me

New WC's are only 6 Litre capacity. But is it? check water level to make sure its high enough! you should be able to adjust the water level from the water inlet valve.

hello, this is a standard toilet you will need to inspect the flapper that is the rubber flap that holds the water up in the tank it works when you pull the lever it pulls the chain upward and lets the water flow if this flapper is old it may not stay up long enough for the water to flow. open the tank top and flush the toilet see if this flapper is staying up long enough and giving the tank enough time to empty if not change this rubber flapper its inexpensive part.
if this is not the reason then you need to adjust your water filler valve there should be a small screw on top of the pivoting float arm
if you have to adjust it for the water limit line inside the tank this will be the proper amount of water needed to flush once completely

also check that the chain lenth on the pull lever is not pulling the flapper down quicker than its supposed to,

try this let me know your results
hope it helps
