Question about Plumbing

1 Answer

I have a rubber expansion joint connecting the home sewar line to the public sewer line in my basement. I have expansive soils and in the 20 years that it's been in place the rubber expansion joint has collapsed and the sewar pipes are just about touching. I want to remove the old rubber expansion joint cut back the sewar pipe and install a new rubber expansion joint. How much space should I have between the sewar pipes when I install the new expansion joint?

It depends on the brand of the expansion joint you purchase. Ive found that they all differ in size and clamp location to some degree. So purchase the coupling first then measure the distance between clamps. Hope this helps.

Sewer lines


Sewer lines can be 3 feet deep to 25-50 feet deep depending on location.
http://waterheatertimer.org/Sewer-construction.html
Residential sewer lines are generally 3-5 feet on flat yard depending on local code.
Deeper lines if house is on hill etc.
Local permit board might have drawings and general elevation.
Locate manhole near house to determine which direction main sewer line runs. Main sewer line will be 20 or more feet deep. However homes do not connect at that depth. Homes connect at shallower depth on a branch pipe, and then branch drains into the main sewer line.

Leaking hot water heater


If it is older than 15 - 20 years and leaking on the floor under the tank, purchase and install a new appliance, If the T&P valve is leaking, change the valve. If it still leaks, replace the expansion tank which should on the supply water line. Try not to install an expansion tank "on its side". BEFORE YOU DO ANYTHING, make certain your incoming water pressure does not exceed 65 -70 psi. This could be the real problem. If so, install a new water pressure regulator. It is usually located inside the basement wall. In a Garden Home, it may be outside at the curb in the ground by the water meter. It may be in the ground buried near the entry through the foundation. It may be near the water heater.

Where is the expansion valve located on the 2004 KIA Sedona


Kia Sedona expansion FRONT valve located under dash, behind glove box, fan and coil. Evacuate freon first. Disconnect Freon lines from firewall., Lay right front seat back to flat horizontal position and lay on top or totally remove the seat for easier working access. Remove under dash cover, fan, glove box, coil housing, remove coil mounting bolts, remove old expansion valve. (Inspect old valve, if debris inside, blow out coil before installing new valve. If visible debris best to consider replacing REAR expansion valve and DRIER/FILTER in front of radiator too and blow out all lines and coils while servicing.) Use compressor oil to lubricate "O" rings on new FRONT or REAR expansion valve, install valve bolts, reinstall coil bolts to FRONT firewall or REAR frame, reconnect freon lines to firewall in engine compartment. Evacuate AC system, install freon (35 1/2 ounces, nominal 3 pounds), check system for leaks, check for proper operation, enjoy.

I am gone to put a new compressor on and somone recomended I change the expansion valve.Where is the a/c expansion valve locate and how do you change it?


It depends WHY its being replaced. If the compressor is destroyed and metal is in the lines, then the condenser should be flushed,and rubber lines replaced. It should be at the firewall where the lines connect to the evaporator. This is a job for a A?C shop. if you dont know what you are doing it can cost more.

Leaking sewer pipe


Depending on how many pipes you have connected in the run from the toilet to the concrete pipe, I would replace all of it with plastic pipe and a new soil pipe if I could find one, if not put the plastic in the soil pipe and pour a concrete patch to fix the hole. Without seeing what you have there, it is hard to say for sure. But cast iron is not used much these days and a job to fix, cut, seal, repair, most are replaced. Hope this helps.

I have vented air out of my Heatslave 20/25 EXPANSION TANK


Yes, you have let the air out of the expansion tank. You can not or should you have to vent an expansion tank. There is a rubber diaphram in the tank so just read the label on the tank for the proper psi/bar and put air in to that amount through the air valve. Problem solved.
