Home Water Pressure - What's too high?
Comments (7)In a municipal water supply system the static head pressure on the system is primarily generated by means of water towers. Water exerts 0.434psi per/ft on a vertical column of liquid. (Vertical Static Head) In order to insure that the system will maintain the required code minimum of 45psi the support tower is 105' tall above average terrain to the base of the storage tank. (105' x 0,434psi= 45.57psi) The storage tank on the top of the tower may then be as much as 92ft higher. (0.434psi x 92' = 39.92psi) From this we can easily see that when the storage tank is empty we still have a static head pressure of 45psi, however when the tank is full the static head pressure at the ground level would be 45psi + 40psi = 85psi. The storage tank is then fitted with a pump controlled by a float system very similar to the fill valve in a toilet tank. Wherever practical the system is allowed to use the water from the tank during the day and the pumps are set up to refill the tank at night when the electrical supply for the pumps is on an off peak demand. Generally a municipal water supply will provide the highest static head pressure to your house early in the morning when the tank is full, but that pressure may decrease throughout the day as the water level in the storage tank drops. To this point we have discussed the pressure above average terrain however the actual pressure at your faucet is a net result of the physical differential between the elevation of your faucet and the top surface of the water in the storage tank. If your house is substantially above the average terrain elevation at the storage tank your water pressure will be less than the average for the community, and conversely, if your house is below average terrain your water pressure will be higher. By example, I am familiar with one community in W.PA where the town is built on steep hills. While the municipal water system can provide water pressures within the prescribed code range of 45-80psi for the majority of the community, there are neighborhoods at the bottom of the hills where all structures must be fitted with PRV's. On the other hand, some of the structures on the top of the hills actually require boost pumps to maintain code minimum. As you can see from this, during the course of a day the line pressure could vary by as much as 40psi, depending upon the actual level of the water in the municipal storage tank. For this reason we do not install pressure gauges on systems supplied by a municipal water supplier because the gauge would not provide any truly useful information, and it would only cause undue apprehension of the part of the untrained homeowner, which would then results in hundreds of unwarranted complaints to the water supplier....See MoreNew AC not keeping house cool enough.

Comments (62)The contractor probably does not want to recalculate the load calculation because he may find a mistake and then you will use it against him. The calculation is probably correct. I am a little skeptical about the duct loss. What he has seems low. I would want an explanation on how that number was generated. There could be an additional 0.5 ton of loss that is missing just in duct losses. I am also concerned that this is the first time he has installed this equipment and in 5 trips he has not been able to solve the problem. When you talk to American Standard, tell them the contractor is having problems getting the equipment to work correctly. Installation issues are not their problem. Let them know you have a load calculation and the unit size is matched to the calculation, but the equipment does not seem to working as per the spec sheet. Tell them it is a new installation and with new duct work. Hopefully they will work with you and send someone to inspect the system....See MoreAppraisal was too low
Comments (31)Even though the location isn't as nice, he will have accounted for that less desirable location with a location adjustment. He should have, but he didn't. He didn't make any location adjustments. He also didn't have to go very far to find a similar property. There is one down the street that he didn't use at all and one about a mile away that he also didn't use. They were listed as party room for the swimming pools, but still had a finished room, a kitchenish area, and a bathroom. I do think all six comps were used in the valuation. If you add all the totals, divide by six, you get the exact number he valued ours. If only 1, 2, and 3 are averaged, it is an even lower value - over $40K lower than the sale price....See MoreNew Construction-Front entry step in to house too high-Not to code
Comments (38)I am so sorry! Your last sentence breaks my heart for you. :( I just wrote a detailed reply - just to have it deleted. Grr. I have looked into this a little (I am not a builder or anything - just through Google) and it seems that many houses have a small step up (2-4 inches) into their house. Apparently it is to help keep weather from entering when the door is open. You have a porch, so this wouldn't be much of an issue BUT the point is: there can be a "mini" step up without it being a tripping hazard. Our home ( we rent ) has this and I have never even thought about it! The fact that there is a door frame, and usually different flooring, gives our brain the info it needs to understand. Does that make sense? Someone suggested something similar earlier in this conversation: build a step that is the same rise as the others you have (are there others? I can't tell from your photo). Make it wider than your front door (it will look better this way). Then the last inch or so will just be part of the natural step into your home. If you are skeptical, you could build a temporary one out of wood (a couple 2x6s would work), and try it. :) Anyway, I am praying (hope that is okay!) that you will see one thing every day (even if it is little) that you love about living in your new home - to help offset your frustration. Sincerely, C....See Morencrealestateguy
