Thread: Q: for plumbers

I connected my house outlets to mains pressure and used fusiotherm piping - best stuff available , as I was sick of shit pressure now its AWESOME.

Want decent pressure

Same here at work. Cant even wash your car with the hose. Got room for a 2000 or even 1000 litre tank to put someplace where it wont be an eyesore ?
Put mains in the top on a ballcock. Fit a powerfull water pump on the botton side (so flooded suction) small air pressure tank and electronic controller
then replace your tap washers and stand back !! Sometimes its the only fix and costs a little but once done its done. Unless on a slope no power may
mean no water so doesnt hurt to have a garden tap before the pump so you can get some simply by gravity. Then in the big quake you ll also have a three or four day water supply
dependant on tank size ??
Smallest tank you can get to turn the water over quickly without letting the pump run dry although the good un Chink pumps have run dry protection.
Tank in the shade to keep temp down a bit.
hey even 500 litres may do it dependant on water usage per day. Watch your neighbours faces when you hose them down from your front lawn ... 25 or 32mm from pump to house seeing you re pulling it too bits..

Thats one solution. Sure there may be others ...

Neighbours got the same problem? Looks likely to be council supply

Need to find out

Did think about putting a small pneupress tank in

This is tank height. As you can see not a lot of drop

If you re running on that height gravity feed a pneu tank by itself I reckon wont help it ll just fill to the pressure available IE that height of gravity and
things will remain the same. Only way to increase pressure if thats all you have is to put in a pump. Only reason to have a reserve tank is if you re boosting their supply
you dont want to come home to find damaged pump cos they turned everyones water off for 1/2 hr whilst dicking around with the supply cos they usually dont tell you.

Pnuepress with a pump yes
We run small units on the ship to boost pressure to areas too far away from the main CW system
Wouldnt be very big due to where it would be fitted and the damn things are worth a fortune

Might just tell the mrs to stop whinging about it LOL

My garden hose takes ,must be 4 or 5 min to fill the dog bucket .

It sucks

If it sucked would it not empty the bucket ??

lol.
There is absolutely no such thing as suction....only the absence of pressure.

Big gum on shared driveway im pretty sure has strangled my alkathen supply pipe, pressure but no flow. Would mean digging up drive to fix and that aint happening.

Cant be right it felt like suction ??? Ha ha Sorry VC just bein a smart bastard...

Ok - so did some poking around today

The gas HW cylinder (old) is fed by a NEFA PR v/v, (been fitted where the header used to be)
Can this be cranked up a little?

I cant find where the mains water enters the house.
The closest outside tap to the rd, is attached to the block of the garage - on the backside there is no pipework - its inside the block

hmmm

You can get a pressure relief vv that fits on the roof overflow but watch the pressure as a low pressure tank may go bang.
The little in line pumps work well have put a couple into some old ladies houses hooked to the shower. Problem is the quality of the chink pumps

That water supply is probably on telecom wireless?

For my house yes the outside tap next to where the incomer is is mains while the house inside was all low pressure, its now all high pressure.



My house is 1968 so its possible yours is the same layout. NB It also acts as a handy drain point if you need to work on the plumbing so I'd suspect its common. Any other taps outside could be either but mains would make the most sense, but having seen the abortions under ppls houses anything is possible.



Yes put a dead head gauge on it, must depend on where in Wellington, my pressure is 90~100psi. (6bar plus) if you have 3bar (45psi) incoming that is a problem.

I cant see the council would put a restrictor in (never heard of it), more likely they damaged the incoming pipe putting in the new valve. Its probably 3/4 inch (20mm) but 1/2inch (15mm) is possible. You shouldnt see a big variation between no flow and full flow a few psi (like 5) at most if you do say the gauge drops 50% there is a damaged pipe somewhere. If its 45psi doubt the council will do much.

If you are putting in a gas unit that needs mains you should be able to find a cut in point before the tank. If possible though convert the house all to mains but that probably means a new hot water cylinder about $1k ish for a stainless steel unit...I see brand new peter cox 10 year stainless steel waranteed units on Trademe quite often. if you think you might do solar heating then put a 300litre one in and not a 180litre thats about $1600.

Oh and the NR valve, I'd expect it to have a filter, might be blocked but unlikely.
