Hi original poster! I know it’s 7 years since you asked this but would love to know what you did. We are not in a similar position with a similar looking house at the back but even steeper. I know that a full extension and lowering the internal floors would be ideal but we can’t afford that and need a 5-7 year fix. Please let us know what you decided and why ☺️

the main water line connecting the street to my house is 65 years old or so. The tree roots over time have put pressure on the line and caused a crack. Ground water is seeping into the line and dripping at a very slow rate but this means MAJOR construction such as digging to the existing line, ripping out the tub and tile work and cement surrounding the line and the plumbing company (will remain nameless here) recommends removing the tree but I don't want to as it provides wonderful shade. Is it not possible to cut or sever the roots causing the damage. I understand this will cause parts of the tree to die. I'm okay with this and trimming back the parts as it does. Furthermore, the company who found the issue (and videotaped it) will excavate but won't replace a damaged tub or tile. They are quoting me $11,220 (also doesn't include tree excavation). I'm looking to have this work done in Oct as I live in the UK and moving back to the US in Sept. I want to be present for the work. I'm looking for ideas on what to do with the tree and if anyone knows any reputable companies in the Alexandria, VA area that will provide service that will be able to perform the required work in addition to re-installing the existing tub and tile. here is an overview of the area. many thanks!

Mains feed, if it is a Quooker fusion, drinking water shouldn't be softened by a full on water softener.

looks like you have an air lock on the pipe system. you need to place a hose on the cold tap to the basin and run it to a cold the main supply that is not on the gravity feed , should be the kitchen sink. turn on the basin tap fully and then turn on the tap to the sink. The high pressure cold feed should force water back into the pipes pushing the air lock back towards the tank and allow water to flow. Make sure you have a secure connection over the taps to prevent the hose pulling off.
