Ok, so
I was wrong about my setup. Coming out of the cistern there is a fitting that is either 1-1/4" or 1-1/2" (I couldn't get close enough to tell bc the pressure tank was in the way & the leaking water was spraying me). The fitting is a reducing fitting so it goes from whatever size is in the cistern down to what looks like 3/4". It goes straight for a couple inches then has a 3/4" shutoff valve (The valve is crooked & hard to reach- I don't like it and want to replace it- but if I remove it, I have to first shut off the pumps & let the water go back down in the cistern. I know the fitting on the cistern screws on to something inside of the cistern & I'm not about to mess with that- last time the pump guy had to climb inside it while someone on the outside held the other part of the fitting in & one of them turned their part to make it tight.
From the 3/4" shutoff it runs a few inches, then has a 90 to take it up
above the level of the pump then another 90 makes it run horizontal. It then has about 4 different unions to splice together a horizontal run. Another 90 makes it go back down and immediately has another 90 that turns it toward the pump. It runs to a reducing fitting that goes from 3/4" to 1-1/4". That fitting threads in to the pump's intake.
I saw a bunch of loose fittings lying around on top of the cistern (un-used ones) and thought they were 1-1/4" but when I got them in good light & read the markings they were 1-1/2". So, either the cistern uses 1-1/2" or my someone (probably my father) bought the wrong size fittings.
So, what I would like to do eventually:
- A) Determine what size fitting attaches to the holding tank & put a foot valve on it if there is no check valve on the outlet side
- B) Get holding tank professionally cleaned bc the inside is absolutely filthy right now
- C) Replace the reducing fitting on the holding tank w/ one that stays the same size
- D) Replace the shutoff valve with a PVC ball valve (these first 4 will require assistance from the well repair/install guy)
- E) Replace the old 3/4" patched up PVC w/ 1-1/4" PVC up to inlet pipe or elbow to inlet pipe & lower it down to same level as pump inlet
- F) Replace 1-1/4" to 3/4" reducing fitting at pump inlet w/ 1-1/4" stainless steel nipple (I think current one is 5" or 6" but I forgot to measure bc I was getting sprayed w/ water- needs to be rectified asap)
- G) Put antivibration pad under pump if there is enough wiggle room to do so
- H) Collect the spare parts sitting on top of the holding tank & store them in an easy-to-access bin to keep them clean
Steps E through F are priority at the moment to stop the leaking. From there I will have to talk to my well guy to find out what parts I need & see about getting stuff fixed up. Anything before that first shutoff valve will be his area of expertise/skill. After that, I can handle things. I will have to temporarily use a reducing fitting to connect after the valve. I need to get my phoneline fixed before I can make calls though. I know I need to order the steel pipe parts before the prices go up again. The price on the pipe I wanted already tripled & it's out of stock now.
So, some questions:
- Since the current straight line going to the pump intake is about 4 to 6 inches, would it be OK to use a 4", 5", or 6" pipe instead of 8"?
- If the pipe is that short, should I go with a PVC fip x socket elbow on the end or should I spend more $ to get the stainless steel street elbow & then go to PVC?
- Is there a standard size outlet on holding tanks? (1-1/4" or 1-1/2"?) It's an old one. It's not easy to get close enough to examine the fitting.
- If the pipes coming out of the pump are galvanized steel instead of stainless steel, would it hurt to use a galvanized steel pipe instead of stainless steel at the intake?
- What sort of sealant should I use on the threads? Would I do teflon tape for PVC to steel & the rectorseal 5 for where the steel threads in to the pump? Or would I use rectorseal on steel to PVC too? Or would rectorseal be a problem if the steel pipe ever needs to be removed from the pump?
- Any other suggestions other than to stop procrastinating & get it done?
Here is a photo I took of the pipe going to the intake.
Here's another shot- you can see the pressure tank blocking the view a little
Here's where it comes out of the holding tank
And here's a crappy sketch of the suction side from the holding tank. The pipe going to the inlet is spraying water so I will need to patch it asap. I tried flex tape but it didn't take.
Editing to add that I moved the box & looked more closely- the bit coming out of the holding tank looks to be 1-1/2" with a 1-1/4" fitting inside & then reduces to 3/4". Not sure if that means the opening is 1-1/2" or if it is 1-1/4" & has a sleeve or something to go around. I also discovered that the shutoff does not work. I turned it off for several minutes and the leak didn't even slow-- unless it's water backflowing into the pump...
