Fortic cylinder

[barronbathrooms]

Evening all! Went to look at a bathroom today for one of my landlords. In a ground floor flat direct fortic cylinder about 600m off floor pressure really poor. Is there a way to increase flow rate. Thought about a pump but obviously the tank above is really small so may not be able to cope with demand(bath, whb and sink) anyone any ideas!

Whats incoming mains pressure and flow like? Direct unvented cylinder?

The only way your likely to improve the supply is spend lots of money.
The fly in the ointment is that there us a landlord involved.
Best just fit a triton wall mounted shower pump to appease the tenant.

Changing system not an option(landlord tight as ducks nether region) to be honest don't think incoming was to good 12 lt per min tops.

Suggested shower but still doesn't solve hot water. It's quicker to fill sink by boiling a kettle!

Can you raise tank any higher ?

one thing that helps is avoid mixer taps and taps that dont work well on low pressures.

 

[dave1]

Or lower the tap ;-)

 

[jtsplumbing]

Can you still get full-flow taps for these low pres systems ??

 

[AWheating]

and remove the iso valves or fit full bores.

Nothing you can do mate, landlord is too tight to spend Christmas, and tenant won't improve a rented property.
Walk away.

If the correct taps are fitted with copper tails remove the hw outlet from cylinder and check for a build up of crap, I've found quite a few blocked here, also check gate valve, but as you know pressure will never be great on these

I have seen this before pal and they had a pump (no markings on it tho) on the H/W draw off and worked ok. Asked about on here some time ago if anyone knew or seen it before for future ref but to no avail. BUT there is something somewhere out there!

Thanks for replies.

Never seen this Grundfos, so would it pump the down service to the cylinder or suck from it ? Wouldn't it cavitate like crazy sucking from the cylinder, is it regenerative ?

 

[chris watkins]

I was not suggesting it would work on the Fortic but it is only a small pump to auto- boost hot or cold supplies it has very small head / pressure, centrifuge & very unlikely to cavitate unless HW temp very high.
It may be an option?

 

[Mickyplumb]

Good idea. Have you installed one ?

 

[chris watkins]

No sorry

 

[Mickyplumb]

No sorry

Thanks for pointing it out though. Looks like a bit of a life saver with all the high pressure taps on the market these days that people want only to find they have a gravity system. Every LPM helps !!

 

[barronbathrooms]

That's an interest piece of kit Chris

It has been out a while, always good to tuck these kind of products away in the old brain just in case you get stuck. It looked good for giving HW systems a bit of a boost say when outlets getting close to tanks & fully auto as well. Don't know how much though ??
