I don't have the same pressure at my house as I did at my mother's house. I have city water and she has well water, would this make a difference?
Would it make a difference if the hose is hooked up in the front of the house or the back? Should it be hooked up closest to the hook-up from the street?

Too much pressure on city water input. Use a regulator pressure. or, shut up the city water valve outside open the TP valve and a hot water faucet inside the house and let water drain out until it stop running out. Close TP valve, hot water faucet and then open city water valve. That will create and air cushion on top of the TP valve inside the tank and then no more leak on TP valve
There may be a pressure setting on your outfit but My feeling is -- your problem will be low pressure on your water line. Most pressure settings is to keep from having too much pressure on what your running. For instance our city water pressure is 70 lbs but in order to keep my furnace boiler system at 16 lbs I have to install a pressure reducer.
That depends. City water? Shared well? Personal well? If you have your own well, it's pretty common to maintain about 50psi at the tank. City water may go to 100psi or higher, which is why many people have a pressure regulator installed to prevent it from going above about 65psi. I don't like to see anything above 65psi in a two-story house, or 50psi in a one-story house (it takes extra pressure to lift water higher); that's plenty of pressure to do everything you need to do, and not enough to blast the skin off your cheeks when you take a shower.
Have you ever tried to pump water for a fountain... It is so tough and you need larger and larger pumps to get it to go 7 feet high to let's say 10 feet high. Having the on demand water heater in the attic dramatically drops it's pressure. It's best to feed it with a 1 inch or at least 3/4 inch pipe downstairs before it splits the hot and the cold to get the best pressure everywhere then the least pressure will be when it reaches the 2nd floor. but the heater won't cut out because the pressure it even greater downstairs.
Do you have a well and/or, do you have an expansion tank installed in the system. Alot of homes, almost all with wells and, alot now with city water, install expansion(pressurized) tanks in the line to prevent surges in pressure and temperature fluctuations. The tank would either be outside by the pump or, could be installed on or near the water heater. If these tanks go bad or, if they lose pressure, they can't provide the cushion to prevent this from happening. Also when they go bad they will become saturated with water and adding pressure to the tank may lessen the problem but, again, it can't provide the cushion.
Most states only require that the locality only provide you 10 psi at meter and that's just plain wrong because at 10 psi it will not even provide enough pressure to take water to shower head.Most house have about 50 psi you can not have above 70 psi or it will cause a lot of problems you have to install a pressurereducing valve for high pressure for too little of pressure you may have to install a pressurebooster pump,which is around 500.00 plus installation.If city not providing enough psi contact pubic works officials tell them if you don't get you more pressure you will install booster system and that will **** their lines dry and cause all the neighborhood to be calling about no water,thats what I did and had engineers and workers provided me with 55 psi at my meter.
COLD MIX, HEATER DEACTIVATES If inlet water temperature is over 70°F due to geographic location, water maybe very hot out of the tap. This requires a lot of cold water to be added with it in order to attain a useable hot water temperature. The addition of too much cold water will overpower hot water demand from the tankless water heater. This slows the flow within the tankless water heater, decreasing it below activation point, which shuts off the heater. The end result is nothing but cold water coming out of the outlet. See: TWH E2-04 Overcoming fluctuating temperatures [PDF].
FLUCTUATING WATER PRESSURE If the water pressure in the home is erratic and the water flow is not consistent while a tap is opened, then the temperature of hot water will fluctuate. The minimum water pressure for the home should be 30psi or greater. For people on well systems the minimum pressure range is 30-50psi. The use of a pressure reducing/regulating valve is an effective way to maintain constant water pressure to the water heater. Watts brand 25AUB- ¾" or N35B-¾" pressure reducing/regulating valves or equivalent is suggested.
CHANGING FLOW RATE Major changes in flow rate can adversely affect the output water temperature of the heater. Increases from one major fixture running to multiple fixtures running at one time can cause the temperature to fluctuate. Stay within the heater's specifications. See: TWH E2-03 Outlet temperature vs. flow rate [PDF].
No it more then likely is because of fluctuating pressures...this could be because of other water usage in the house or even in the water entering the house...to see hwat it is the water pressure would need to be monitored at different locations to find the source of the problem...likely if it happens when somewhen else in the house flushes a toilet then you know where it is...
it is normal to loose pressure from the filter it must have very small holes in it for the water to pass threw so it can trap dirt and particales from both well and city water. it is normal for it to cut back on pressure, it will cut back more and more as it catches the things that you are filtering out. what you might want to do is filter your drinking water only, under your sink .dont try shower and outside faucets. and you wont have to replace it as often. well good luck and good day to you... sawdust46
