Cutting a long story short...

I have a bare room with no plumbing which im going to convert to a bathroom and another which is a small bathroom at the moment.

Im proposing to connect a Booster pump that supplies the Hot and Cold to the current small bathroom to boost the output to the Manual Mixer shower to go in there, but i need to get a supply to the other bathroom too.

I could use the feeds to the smaller bathroom from the booster pump and direct it to the new bathroom and drop it down from the loft to supply the new bathroom.

But my worry is, will the pump be ok?

Would it be better to use 2 pums, one for eac bathroom???

Any advice?

Lets hope offical PF Plumber Tiff got time to help you inbetween his "Tea and Hob Nobs" sessions.

vroooom ptssssh

have you tested the shower off the main water pressure to note that it isnt satisfactory and that you will NEED the pump?

CosRush

The system is gravity fed, and in all my other previous houses ive always used a booster pump and have been very impressed with the performance.

The biggest problem is the head of pressure created by having the plumbing in the loft dropping down into each bathroom, where the storage tank is only 6 inches above......

Hence why the booster pump overcomes this.

My question really is about the best layout and or pump choices....

Rob-ZetecS

i beleive you should use two pumps as if both bathrooms in use at same time would cause poor flow.

but because of this you will need two cold feeds from tank and two hw draw offs from cylinder

CosRush

thats exactly what i thought.

Ive been looking at pumps though, and there are some heavy duty ones which list in the spec they are designed for multiple showers/outlets....

Not sure if this would be better or to stick with 2 pumps, as the cost isn't really alot between the 2.

*edited to remove Crap spelling*

TIFF

You will not need to pump the cold as it is mains feed.

As for pumping the hot, you will need to be careful, as if both bathrooms are being used or hot water is being drawn off, you will run the Hot water tank in the roof dry VERY quickly unless you get a much bigger one.

Rob-ZetecS

well im not a plumber i do gas so dont really know much about pumps etc but for ease of installation the one pump would be alot better however you'll need correct pipe sizes this pump MAY require 28mm pipe work and youve probably only got 22mm but i may be wrong ?

CosRush

The storage tank in the loft is cold water, the Hot water cylinder in is my airing cupboard.

The pump would be supplied cold water from the storage tank at Gravity along with the hot take off from the cylinder...

CosRush

The plumbing for both is going to fitted new.

Ive obviously not explained the layout very well...im not suprised

One room has some plumbing which is being replaced, the other room has no plumbing at all....

Rob-ZetecS

im assuming the cold to your shower is gravity at the moment?

CosRush

There isn't a shower at the moment.....

TIFF

The tank in the roof supplys the water that goes into the Hot water cylinder in your airing cupboard. Now once hot water is getting drawn from the cylinder, the cold water from above will be replacing it, Therefore putting COLD water into the HOT water cylinder and causing it to cool down. You then have the danger of pumping more water through the hot taps than is going into the Tank in the roof, this will result in no hot water.

Your cold main should be around the 5bar mark where it comes into the house, that will be enough to run a few bathrooms easily

Rob-ZetecS

god help the man who tries to work in your house!

CosRush

Thanks for the replies fella's...

Im just off to bath the kids, so when i come back i'll try and explain this better

CosRush

I did say 'the Manual Mixer shower to go in there'

CosRush

Tiff,
I understand exactly what you're saying, so what would you recommend is the best plan of action.

In simplist terms, there are 2 rooms with no plumbing.

1 room requires a Shower (not electric)

the other room a bath sink and shower........

I need to drop all plumbing from the loft as i do not want to dig up the floor.

Im assuming that with the hot outlet from the hot tank feeding back up into te loft across and then down into each of the 2 rooms, there would be insufficient head pressure to flow a decent amount through the bath taps as well as a shower???

Ive had this before and used a booster pump connected to a direct feed from the cold tank at gravity and then the hot from the hot tank also at gravity, these 2 outlets from the pump then ran up into the loft, across and droppped down into the bathroom.
I had no problems and it was easy to install, but this time i have 2 bathrooms....

TIFF

Pump the 2 showers with 1 good Aqualiesur pump, they are upto the job.

Uprate the tank in the roof (60 gallon) and get it as high as possible, this will allow plenty of water and enough head to supply the cold side of the shower

CosRush

Tiff,

Like this???

TIFF

Thats the Puppy

PMSL@ the drawing too

CosRush

Tiff,

Any particular Aqualiesur model pump you'd recommend???

drawing had to be quick....would you prefered it if i'd tiled the walls

TIFF

If you are going to run the 2 showers then go for the Aquaforce 3. It will be up to the job

CosRush

Thanks Tiff and everybody else for the input...

Im off now to find the cheapest price for a new pump and a 60lt tank..........

TIFF

60 GALLON

CosRush

ooops

yes Gallon

RSrussell

I don't care what they say about Tiff, his a top bloke and a good plumber

CosRush

Tiff,

Does you're knowledge extend to Heating systems as well???

if so, i have another Q you might be able to help with...

TIFF

Shoot mate, the bill is still open

CosRush

My central heating is a microbore system, with the manifold in a cupboard along with the heating circ. pump.

I need to move 2 radiators so wonder how the pipework can be done.

there are a couple of spare conn's on the manifold.
Is it possible to connect to these and route up againinto the loft and drop down in box sections to supply to rads in the rooms? didn't know if there would be any issues with the pipework going vertical up into the loft.........

I know its done with normal 15mm pipe but never seen it with microbore/manifold.

If i can connect to the manifold, can you connect more than one rad to a connection or not???

TIFF

TBH mate, the microbore pipe is shit and wont hold/flow the heat to the rads if they are on a long run. Usually max 5m in Microbore.

You would be better of running 15mm pipe to the rads, or as close to the rads as possible mate. It is not worth putting it in and finding it not working.

HTH

CosRush

no probs putting the 15mm stuff in, but how would i connect it to the manifold?

adaptor?

could i connect the new rads in series off the connection?

TIFF

Just connect it with a reducer as close to the manifold as possible, or connect to the pipes that supply the manifold

CosRush

Cheers Fella

Pint of 'Tap Washers' on its way to you....

Seriously though, Big Thanks.

TIFF

No problem mate
