Increase water pressure in old neighbor hood home

Page 3 of 3  


For sure on Pex but one does not instantly assume a problem like Halliburton has done and proceed to tear out pipe without _knowing_ it is a problem.
As for "disturbing" pipe. Two pipe wrenches properly applied will only disturb tht one fitting. I have worked on...umm...4 houses now and all of them were galv and all older than 50 years. Never had a leak develope anywhere in the system..other than a couple on the joints I worked. In this area 50 year old galv pipe _not buried_ will be very clean inside.

At least spend a LITTLE time educating yourself instead of diving in wide-eyed and excited on the first person who says what you want to hear.
The fact that it's limited to one shower is even MORE proof that it's an issue with your pipes, not the pressure. Assuming that there is no flow restrictor on the shower.
A booster pump and tank is NOT a solution for old clogged pipes, unless the plan involves flooding the house and then using the insurance money to hire a plumber to redo all the pipes.
Most likely, the shower head is an old-fashioned high-flow unit, and the pipes or valve to that shower have partially clogged, and it cannot get enough water to maintain pressure.
Here's a quick bandaid workaround that'll make your showers more pleasant: Walmart has a small, simple metal low-flow shower head. It looks like a garden hose nozzle, except chrome. While it cuts down on the amount of water, it brings the pressure back up so it FEELS like you're getting a full-force 5-star hotel shower.
Back at the folks' house, the water barely dribbled out the shower head. Low pressure due to the well and a long pipe run to the shower. After they put one of these Walmart heads on, it was like showering under a pressure washer! With normal water pressure and no flow issues, these heads give the best back massages.

Different problem. If the pressure is low at one fixture, it is a piping or faucet problem. It may be as simple as cleaning or replacing the shower head. If all the faucets are turned off, the pressure in the system is going to be the same every place. If, when the faucet is open, the pressure of the shower drops there is a restriction of the flow. Find and fix it.

You can put a booster pump on it and a bladder tank just as if you had a well supply. You'll need a check valve as well. Have you put a guage on it to see what the current presure is now? As other point out if the pipes have a lot of scale built up inside them you can have a volume issue. Increasing the pressure can overcome that to a degree but also puts a bigger load on the system. Increases your chances of leaks. First step is to get a pressure guage and see. You can get ones that screw on to your outdoor faucet.

often galvanized lines crush when they are badly rusted, so using any wrench can cause more troubles.
at least with this info the OP will be aware he might need replumbed, and for safety sake should turn off his main valve when not home, so he doesnt come home to a flood.

We had our pipes replaced a few months ago using a company called Repipe Specialists. They knew exactly what walls to open and where. They tore out the galvanized and installed copper--in one day--in our split level with 2.5 bathrooms. We had them install all new faucets as well. After the city inspector checked it out they came back and patched the walls ready for painting.
My main issue was dealing with ceramic tile. They had to remove tile in one bathroom and I could not find new tile that exactly matched. Rather than tear all the walls out I elected to remove about 40 tiles so they could be reused. Using a Multi-Max and heat gun I was able to save almost all the tiles for reuse. I bought a few that were a close match for use behind the toilet. The 60 year old tiles came off rather easily. Those that had been taken down and replaced 20 years ago for drywall repair were harder to remove.
